Linear equation is an algebraic equation that is a representation of the straight line. Linear equations are composed of variables and constants. These equations are of first-order, that is, the highest power of any of the involved variables i.e. 1. It can also be considered as a polynomial of degree 1. Linear equations containing only one variable are called homogeneous equations. The corresponding variable is called the homogeneous variables.

For instance,

300 / 2 = 150 dollars.

150 /1.64 = 91.46 British pounds

150 /1.32 =113.64 Euros

113.64 - 91.46 =22.18 ≅ 22

Thus Kathy has 22 more Euros than British pounds.

The account be worth in 7 months is 375.725 .

Amount (A) is the total money paid back at the end of the time period for which it was borrowed. The total amount formula in case of simple interest can also be written as: A = P(1 + RT)

Here, A = Total amount after the given time period.

Given that,

P = $350, R = 1.05%, T = 7 month

The simple interest equation uses "t" as years, but is just cycles, using an APR rate.

now, if we never mind "t" as years and just use it as an interest cycle, then we can say the rate is 1.05% and the period is 7 cycles.

A = P(1 + RT)

   = 350(1+1.05%×7)

   = 350(1+0.0105×7)

The maximum value of P = x + 6y subject to the constraints is 9

The objective function is given as:

P = x + 6y

The constraints are given as:

2x + 4y ≤ 10

x + 9y ≤ 12

x≥0 y≥0

Rewrite 2x + 4y ≤ 10 and x + 9y ≤ 12 as equations

2x + 4y = 10

x + 9y = 12

Divide 2x + 4y = 10  through by 2

x + 2y = 5

Subtract x + 2y = 5 from x + 9y = 12

x - x + 9y - 2y = 12 - 5

Evaluate the difference

7y = 7

Divide by 7

y = 1

Substitute y = 1 in x + 2y = 5

x + 2(1) = 5

Solve for x

x = 3

So, we have

(x, y) = (3, 1)

Substitute (x, y) = (3, 1) in P = x + 6y

Answer:

Given,

y=x³ ,0≤x≤2

We have to find the surface area of the surface by rotating the curve about the x axis.

For rotation about the x axis, the surface area formula is given by-

s=2π∫ᵇₐ y√1+(y)² dx

y=x³

y'=3x²

By rotating the curve y=x³ about the x axis in the interval [0,2]

s=2π∫₀²(x³)√1+(3x²)² dx

let u=1+9x⁴

du=36x³dx

dx/36x³

Substituting u and du in the integral,

s= 2π∫₀²(x³)√u du/36x³

s= 2π∫₀²√u du

s= 2π/36.2/3[u.3/2]₀²

s= π/27[(145)³/²-(1)³/²]

s= π/27 [1746.03-1]

s= π/27 [1745.03]

s= 64.67π

Answer:

is 54, 45, 36, 27, 18

Step-by-step explanation:

Recursive formulas give us two pieces of information:

1. The first term of the sequence

2. The pattern rule to get any term from the term that comes before it

In the formula given,

n is any term number

f(n) is the nth term

This means

f(1) is the first term

f(f-1) is the term before the nth term

To find the first five numbers in this arithmetic sequence, we know the formula has given us these two pieces of information:

1. The first term is 54

2. The rule to get any term from its previous term is -9

So, we know the sequence for this formula is 54, 45, 36, 27, 18 because starting off with 54, then minus 9 from every sum gives us the following equations

54-9=45

45-9=36

The distributions of data can be characterized along three aspects or dimensions, namely location, spread, and shape. The spread (variance, range, interquartile range) aspects represent variation of the data or the spread of the data distributions.

About the Distribution of Data:

The idea of a distribution is fundamental to illustrating any output from a production process. Any manufacturing process output will not always produce the same value when it is measured, leading to distributions.

The measured values will naturally disperse around a central tendency value. A distribution is the name given to this dispersion around a core value. It is characterized by 3 aspects - location, spread, and shape.

Mean or median represent the location of the distribution numerically. Most common numerical measures that represent the spread are variance, range, and interquartile range. Skewness or kurtosis tell about the shape of the distribution.

Answer:

$9600 saving / year

Step-by-step explanation:

1/5 of $21000 = 21000 / 5 = $4200 / month on rent

3/7 of $21000 = (21000 / 7) x 3 = $9000 / month on food (shocking right :) food is expensive)

1/3 of $21000 = 21000 / 3 = $7000 on other expenses / month

total savings/month = salary/month - rent/month - food/month - other expenses/month

total savings/month = 21000 - 4200 - 9000 - 7000

total savings/month = $800

BUT the question asks for savings per year. therefore, we must multiply the savings per month by total months per year (12)

800 x 12 = $9600

the person's total savings per year, with a salary of $21000 per month, is equal to $9600 per year

The polynomial cannot be factored in because it exists prime. Since 112 exists not a perfect square number so we cannot estimate the factors of the given equation.

In a quadratic equation ax² + bx + c = 0

when (b² - 4ac) exists a perfect square only then we can factorize the equation.

In the given equation x² - 8x - 12 we have to determine the value of

b² - 4ac

From the equation, we get b = -8 and c = -12

b²- 4ac = (-8)² - 4(1)(-12)

Step-by-step explanation:

the solution of the system of linear equations is:

x = 6/11

y = -4/11

Here we have the system of equations:

To solve the system, we can see that y is already isolated in both sides, then we get:

(-5/2)*x + 1 = 3x - 2

Now we can solve this for x:

(-5/2)*x + 1 = 3x - 2

2 + 1 = 3x + (5/2)*x

3 = (6/2)*x + (5/2)*x

3 = (11/2)*x

(2/11)*3 = x

6/11 = x

To get the value of y, we evaluate any of the lines in x = 6/11

y = 3*(6/11) - 2 = 18/11 - 2 = 18/11 - 22/11 = -4/11

Answer:

You can find either x or y by applying the Theorem which states that sum of opposite angles of a cyclic quadrilateral is 180°

Step-by-step explanation:

The above is a cyclic quadrilateral.

A Cyclic quadrilateral is having all the vertices of a quadrilateral ( four sided figure) inside a circle, that is a quadrilateral inscribed in a circle.

To find either x or y, we should note:

The sum of opposite angles of a cyclic quadrilateral is 180° or Angles in opposite segment are supplementary.

Therefore,

2x + 2x + 4= 180

4x = 180 - 4

4x = 176

x = 44°

To find y

3y + 8 + y = 180°

4y = 180 - 8

4y = 172

y = 43°

Therefore, you can find either x or y by applying the Theorem which states that sum of opposite angles of a cyclic quadrilateral is 180°

Answer:

x = 4

Step-by-step explanation:
1.Distribute

2. Subtract 2 from both sides
3. Simplify
4. Divide both sides by same factor

5. Simplify
x = 4

Answer: 4

Step-by-step explanation:

We have to try getting x by itself to solve for it. Since we have two sides that are equal to each other, we can add, subtract, multiply, and divide anything on both sides to try to isolate x.

[tex]2(x+1)=10[/tex]

We can first divide the left side and the right side by 2. This would remove the 2 being multiplied on the outside.

[tex]\frac{2(x+1)}{2}=\frac{10}{2}\\x+1=10\div 2\\x+1=5[/tex]

Now, we have a + 1 on the left side that we need to remove to get x by itself. If we are adding something, we can remove that by subtracting the same thing. Hence, we can subtract 1 from both sides to remove the + 1.

[tex]x+1=5\\x+1-1=5-1\\x+0=4\\x=4[/tex]

After all that simplifying, we get that x equals 4.
