how do i write 4x+5y=20 in slope intercept form

Answer:

Step-by-step explanation:

You worked 16 hours and 45 minutes

5 1/2 = 5 hours and 30 minutes

6 3/4 = 6 hours and 45 minutes

4 1/2 = 4 hours and 30 minutes

Add the hour and minutes.

5 hours 30 min + 4 hours 30 min = 10 hours

10 hours + 6 hours 45 min = 16 hours and 45 minutes

The solution to the following equations is given below;

y - 6 = 12

y = 12 + 6

y = 18

-5 + k = 1

k = 1 + 5

k = 6

-2g = -14

g = -14/-2

g = 7

y - 4 = 12

y = 12 + 4

y = 16

12 + u = -12

u = -12 - 12

u = -24

f - 7 = 10

f = 10 + 7

f = 17

8t = 42

t = 42/8

t = 5.25

-9 + z = 18

z = 18 + 9

z = 27

7 + w = 14

w = 14 - 7

w = 7

13 - 5 = 12

8 ≠ 12

D - 2 = -10

D = -10 + 2

D = -8

a. Central angle: Angle BAC

b. A major arc is: Arc BEC

c. A minor arc is: Arc BC

d. Measure of arc BEC in circle A = 260°

e. Measure of arc BC = 100°

According to the central angle theorem the measure of central angle (i.e. angle BAC in circle A) is the same as the measure of the intercepted arc (i.e. arc BC in circle A).

Referring to the image given, a central angle (i.e. angle BAC) is formed by two radii of a circle (i.e. AB and AC in circle A), where the vertex of the angle (i.e. vertex A in circle A) is at the center of the circle.

An arc that is bigger than a semicircle (half a circle) or with a measure greater than 180 degrees is called a major arc of a circle.  

An arc that is smaller than a semicircle (half a circle) or with a measure less than 180 degrees is called a minor arc of a circle.  

a. Central angle in circle A is: ∠BAC

b. Major arc in circle A is: Arc BEC

c. Minor arc in circle A is: Arc BC.

d. Based on the central angle theorem, we have:

Measure of arc BEC in circle A = 360 - 100

Measure of arc BEC in circle A = 260°

e. m∠BAC = 100° [given]

Based on the central angle theorem, we have:

The graph of the parabola can be seen in the image below.

We need to find some points on the parabola, and then draw a curve that connects them.

On the graph you already have the x-intercepts, so you already have two points.

Now let's get another point which is the vertex.

For our parabola:

[tex]y = -x^2 + 10x - 24[/tex]

The vertex is at:

[tex]x = -10/(2*-1) = 5[/tex]

Evaluating in x = 5 we get:

In this question we must make use of rigid transformations to find the location of new points, rigid transformations are transformations used in geometric loci such that Euclidean distance is conserved. In this case, we need to use a kind of rigid transformation known as dilation, which is defined below:

P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]      (1)

Where:

Part A - If we know that O(x, y) = (0, 0), R(x, y) = (- 2, 7) and k = 3, then the coordinates of point R' are:

R'(x, y) = (0, 0) + 3 · [(- 2, 7) - (0, 0)]

R'(x, y) = (- 6, 21)

Part B - If we know that O(x, y) = (- 2, 7), T(x, y) = (4, - 1) and k = 1/2, then the coordinates of point T' are:

T'(x, y) = (- 2, 7) + (1 / 2) · [(4, - 1) - (- 2, 7)]

T'(x, y) = (- 2, 7) + (1 / 2) · (6, - 8)

The number -3 written as a logarithm with a base of 2 is log₂(0.125) or log₂(1/8)

As a general rule, logarithms are mathematical expressions that are written in the form log(x) or ln(x), for natural logarithms

The number is given as:

x = -3

The base of the logarithm is given as:

Base = 2

To rewrite the given number as a base of 2, we take the exponent of the number where the base is 2

This is represented as:

Number =2^-3

Apply the power rule of indices

Number =1/2^3

Evaluate the exponent

Number = 1/8

Evaluate the quotient

The upper estimate and lower estimate become R5 = 16 and L5 = −64

According to the statement

we have given that the some values of the increasing function f and we have to find the lower estimate and upper estimate values.

So, For this purpose, we know that the

the values of x is 10 14 18 22 26 30

And the values of f(x) is −14 −8 −1  1  4  7

So,

Δx = 4 because

L5 = 4(−12 − 6 − 2 + 1 + 3) = −64,

And

R5 = 4(−6 − 2 + 1 + 3 + 8) = 16.

And from these functions we see that the

The function being increasing, the Riemann sum with left endpoint L5 = −64 is a lower estimate,

The quartic equation behind the graph is y = - 2 · x⁴ + 4 · x³ + 6 · x² - 8 · x - 8.

Quartic functions are fourth grade polynomials and according to the fundamental theorem of algebra, such kind of expressions have at least two real roots and at most four real roots. The graph of the picture shows a polynomial with two roots of multiplicity 2: x₁ = - 1, x₂ = 2.

y = a · (x + 1)² · (x - 2)²      (1)

Where a is the leading coefficient.

If we know that (x, y) = (0, 4), then the leading coefficient of the polynomial is:

4 = a · (0 + 1) · (0 - 2)

4 = - 2 · a

a = - 2

Then, the quartic equation is equal to:

y = - 2 · (x + 1)² · (x - 2)²

y = - 2 · (x² + 2 · x + 1) · (x² - 4 · x + 4)

y = - 2 · [(x² + 2 · x + 1) · x² + (x² + 2 · x + 1) · (- 4 · x) + (x² + 2 · x + 1) · 4]

y = - 2 · (x⁴ + 2 · x³ + x² - 4 · x³ - 8 · x² - 4 · x + 4 · x² + 8 · x + 4)

y = - 2 · (x⁴ - 2 · x³ - 3 · x² + 4 · x + 4)

Step-by-step explanation:

Slope = Rise/Run = (7-3)/(9-2) = 4/7

Answer:

4/7

Step-by-step explanation:

The formula to find the slope is: (change in y)/(change in x)

Or also: Rise/Run

The change in y is: 3 --> 7 which is +4

The change in x is: 2 --> 9 which is +7

So the (change in y)/(change in x) will be 4/7.

Since 4/7 cannot be simplified further, that is our final answer.
