which graft shows the solution set for 2x+3>-9

This is the same as writing y = sqrt(4(x+5)) - 1

===============================================

Explanation:

The given graph appears to be a square root function.

The marked points on the curve are:

Reflect those points over the line y = x. This will have us swap the x and y coordinates.

Recall the process of reflecting over y = x means we're looking at the inverse. The inverse of a square root function is a quadratic.

----------

Let's find the quadratic curve that passes through (1,-4), (3,-1) and (5,4).

Plug the coordinates of each point into the template y = ax^2+bx+c.

For instance, plug in x = 1 and y = -4 to get...

y = ax^2+bx+c

-4 = a*1^2+b*1+c

-4 = a+b+c

Do the same for (3,-1) and you should get the equation -1 = 9a+3b+c

Repeat for (5,4) and you should get 4 = 25a+5b+c

We have this system of equations

Use substitution, elimination, or a matrix to solve that system. I'll skip steps, but you should get (a,b,c) = (1/4, 1/2, -19/4) as the solution to that system.

In other words

a = 1/4, b = 1/2, c = -19/4

We go from y = ax^2+bx+c to y = (1/4)x^2+(1/2)x-19/4

----------

Next we complete the square

y = (1/4)x^2+(1/2)x-19/4

y = (1/4)( x^2+2x )-19/4

y = (1/4)( x^2+2x+0 )-19/4

y = (1/4)( x^2+2x+1-1 )-19/4

y = (1/4)( (x^2+2x+1)-1 )-19/4

y = (1/4)( (x+1)^2-1 )-19/4

y = (1/4)(x+1)^2- 1/4 - 19/4

y = (1/4)(x+1)^2 + (-1-19)/4

y = (1/4)(x+1)^2 - 20/4

y = (1/4)(x+1)^2 - 5

The equation is in vertex form with (-1,-5) as the vertex. It's the lowest point on this parabola. Placing it into vertex form allows us to find the inverse fairly quickly.

----------

The last batch of steps is to find the inverse.

Swap x and y. Then solve for y.

y = (1/4)(x+1)^2 - 5

x = (1/4)(y+1)^2 - 5

x+5 = (1/4)(y+1)^2

(1/4)(y+1)^2 = x+5

(y+1)^2 = 4(x+5)

y+1 = sqrt(4(x+5))

y = sqrt(4(x+5)) - 1

I'll let the student check each point to confirm they are on the curve y = sqrt(4(x+5)) - 1.

You can also use a tool like GeoGebra to verify the answer.

Answer:

x = - 1

Step-by-step explanation:

P = [tex]\frac{x-2}{x+1}[/tex]

the denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.

x + 1 = 0 ( subtract 1 from both sides )

x = - 1

P is undefined when x = - 1

Answer:

(x-2)^2 + (y+3)^2 = 5.1^2

Step-by-step explanation:

The equation of a circle is (x-h)^2 + (y-k)^2 = r^2, where h and k are the x and y values of the center of the circle respectively and r stands for the radius.

The center is given to us, at (2, -3) so we can plug that in:

(x-(2))^2 + (y- (-3))^2 = r^2

Simplify:

(x-2)^2 + (y+3)^2 = r^2

We can also solve for the radius by getting another point given to us: (3,2).

Using the pythagorean theorem, we can find how far the two points are away from each other:

a^2 + b^2 = c^2

1^2 + 5^2 = c^2
1 + 25 = c^2

26 = c^2

c ~ 5.1

Plug the radius we solved for in for r:
(x-2)^2 + (y+3)^2 = 5.1^2

The domain of the function y = 3 tan(2/3x) is all real numbers except for x = (3n + ³/₂)π., where n is an integer.

The function is given as: y = 3 tan(2/3x)

The function above is defined for all values of x except where the tangent function is undefined. The tangent function is undefined at angles where the cosine is zero. In this case, the cosine is zero when 2/3x is equal to an odd multiple of π/2.

So we set (2/3)x equal to (2n + 1)π/2, where n is an integer:

(2/3)x = (2n + 1)π/2.

To solve for x, we multiply both sides by 3/2:

x = (3/2)(2n + 1)π/2.

x = (3n + ³/₂)π.

Therefore, the function is undefined when x is equal to (3n + 3/2)π, where n is an integer.

The forecasted level of output for the 15th year would be 14/15000.

To forecast the level of output for the 15th year, we need to analyze the given information about the firm's total production of cars at the end of ten years of operation and its production during the first year.

According to the information provided, the firm's total production of cars at the end of ten years of operation is 14/1500. However, the production of logo cars during the first year is not specified. We need this information to accurately forecast the level of output for the 15th year.

If we assume that the production of logo cars during the first year is constant throughout the ten-year period, we can use the given information to estimate the average annual production. Since we have 14/1500 as the total production over ten years, we can calculate the average annual production as (14/1500) / 10.

(14/1500) / 10 = 14/15000

Therefore, the estimated average annual production is 14/15000.

Now, to forecast the level of output for the 15th year, we can assume that the average annual production remains constant. Therefore, the forecasted production for the 15th year would be the same as the average annual production.

Hence, the forecasted level of output for the 15th year would be 14/15000.

Answer:

To determine the first term of the geometric progression, let's assume it is 'a'. From the given information, we know that:

Second Term = a + 50

(n + 1)th Term = a + 56

We also have the formula for the nth term of a geometric sequence:

nth term = a * r^(n-1)

where 'r' is the common ratio between consecutive terms. Since the difference between consecutive terms remains constant, i.e., 50 for the second term and 56 for the (n + 1)th term, we can set up the equation:

a + 50 = a * r^1

a + 56 = a * r^2

Solve the equations simultaneously:

a + 50 = a * r^1 => a - 50/r = 0

a + 56 = a * r^2 => a - 56/r = 0

Adding the two equations, we get:

2a - (50/r + 56/r) = 0

2a - (50 + 56)/r = 0

Simplifying the equation further, we obtain:

2a - (106/r) = 0

Now, solve for 'a':

2a - (106/r) = 0

2a = (106/r)

=> 2a = 106/r

The value of 'a' depends on the value of 'r', so we cannot determine its exact value without knowing 'r'. However, once we know 'r', we can calculate the value of 'a'.

The equation of the linear relationship in slope-intercept form is y = 2x - 8. Option A is the correct answer.

To determine the equation of the linear relationship in slope-intercept form based on the table, we need to find the slope and y-intercept.

By observing the table, we can calculate the slope by selecting any two points. Let's choose the points (0, -8) and (4, 0).

Slope (m) = (change in y) / (change in x)

= (0 - (-8)) / (4 - 0)

= 8 / 4

= 2

Now that we have the slope, we can find the y-intercept by substituting the values of one point and the slope into the equation y = mx + b and solving for b.

Using the point (0, -8):

-8 = 2(0) + b

b = -8

Answer: $227,226.51

Step-by-step explanation:

First, we need to convert the period to weeks.

9 1/2 years = 9.5 years

1 year = 52 weeks

9.5 years = 494 weeks

Next, we can use the formula for the future value of an annuity:

FV = (PMT x (((1 + r/n)^(n*t)) - 1)) / (r/n)

where:

PMT = payment amount per period

r = annual interest rate

n = number of compounding periods per year

t = number of years

Plugging in the given values:

PMT = $300

r = 0.055 (5.5% expressed as a decimal)

n = 52 (compounded weekly)

t = 9.5 years = 494 weeks

FV = ($300 x (((1 + 0.055/52)^(52*494)) - 1)) / (0.055/52)

FV = $227,226.51

Therefore, the future value of the annuity is approximately $227,226.51.

To create a box from a flat piece of metal, you typically cut equal-sized squares from each corner, then fold up the sides. This effectively reduces the size of the base of the final box by twice the length of the side of the squares.

The original size of the piece of tin is 40 cm x 70 cm. Let's represent the length of the side of the squares cut from the corners as x (in cm). After the squares are removed, the size of the base of the box will be (40 - 2x) cm by (70 - 2x) cm.

The problem states that the base area of the box is 1984 cm^2. Thus, we can set up the following equation:

(40 - 2x) * (70 - 2x) = 1984.

Expanding this equation gives:

2800 - 140x - 80x + 4x^2 = 1984,

4x^2 - 220x + 2800 = 1984,

4x^2 - 220x + 816 = 0.

Dividing through by 4 gives:

x^2 - 55x + 204 = 0.

This quadratic equation can be solved using the quadratic formula, x = [ -b ± sqrt(b^2 - 4ac) ] / 2a. Here, a = 1, b = -55, and c = 204.

The discriminant, b^2 - 4ac = (-55)^2 - 4*1*204 = 3025 - 816 = 2209.

The square root of 2209 is 47.

Therefore, the solutions for x are:

x = [55 ± 47] / 2

x = 51, 4.

Since the length of the sides of the squares (x) must be less than half the length of the shorter side of the original tin piece (which is 40 cm / 2 = 20 cm), the valid solution is x = 4 cm. Thus, each square cut from the corners is 4 cm on a side.

b. The vertical shift of the graph of G(x) compared to the graph of F(x) is an upward shift of 1 unit, while there is no horizontal shift between the two graphs.

In the functions G(x) = 2^(-x) and F(x) = 2^x:

Vertical Shift:

The vertical shift refers to the movement of a graph up or down along the y-axis. In this case, comparing G(x) = 2^(-x) to F(x) = 2^x, there is a vertical shift present.

The graph of F(x) = 2^x has its vertex (the lowest point of the graph) at the point (0, 1) on the coordinate plane.

The graph of G(x) = 2^(-x) is obtained by reflecting the graph of F(x) about the x-axis. This reflection results in a vertical shift of the graph. The graph of G(x) will have its vertex (the highest point of the graph) at the point (0, 1).

Therefore, the vertical shift of the graph of G(x) compared to the graph of F(x) is an upward shift of 1 unit.

Horizontal Shift:

The horizontal shift refers to the movement of a graph left or right along the x-axis. In this case, comparing G(x) = 2^(-x) to F(x) = 2^x, there is no horizontal shift present.

Both G(x) = 2^(-x) and F(x) = 2^x have their graphs centered at the y-axis, passing through the point (0, 1). Therefore, there is no horizontal shift between the two functions.

Typically, when making a batch, there is a specific ratio of water to flour. Let's assume the ratio is 1:2, meaning for every 1 pound of flour, we need 2 pounds of water.

For a double batch, we need to multiply the amount of flour by 2:
