Answer:

1. z = 5,  2. w = 9

Step-by-step explanation:

1. 5z - 4 = 21

5z = 21 + 4

5z = 25

z = 25/5

z = 5

2. w/9 + 2 = 3

w/9 = 3 - 2

w/9 = 1

w = 1 x 9

w = 9

Interquartile Range

The interquartile range of an observation variable is the difference of its upper and lower quartiles. It is a measure of how far apart the middle portion of data spreads in value.

Interquartile Range = U pper Quartile − Lower Quartile

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Angle ABC is an exterior angle of the triangle.

Angles D and C are its remote interior angles.

m<ABC = m<D + m<C

12x - 2 = 57 + 7x - 4

Combine like terms on the right side.

12x - 2 = 7x + 53

Subtract 7x from both sides.

5x - 2 = 53

Add 2 to both sides.

5x = 55

Divide both sides by 5.

x = 11

Answer: x = 11

Answer:

According to exterior angle property, one of the exterior angles of a triangle is equal to the sum of the opposite 2 interior angles.

Thus,

12x-2= 57+7x-4

= 12x = 57-4+7x

= 12x = 53+7x

= 53= 7x-12x

= 53=-5x

= 53÷-5=x

= x= 10.6

Thus x= 10.6

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (3, - 3)

m = [tex]\frac{-3-(-5)}{3-(-1)}[/tex] = [tex]\frac{-3+5}{3+1}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

Jeanette is the friend walking at the same rate as Caroline. This is because Jeanette also takes 1/5 of an hour to walk a mile.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

It takes Caroline 1/5 of an hour to walk a mile. Four of Caroline's friends time themselves on their own walk of different lengths. Which friend is walking at the same rate as Caroline? If:

David walked 1/2 a mile in 2/5 an hour

Jeanette walked 1/2 a mile in a 1/10 an hour

Kay walked 1/5 a mile 1/2 a hour

Mark walked 1/3 a mile in 3/5 an hour

The explanation of the answer is now given as follows:

To determine which friend is walking at the same rate as Caroline, we first convert their rate to number hours it takes to walk a mile as follows:

a. David walked 1/2 a mile in 2/5 an hour

This implies that:

(1 / 2) * 2 = 2/2 = 1 mile

(2 / 5) * 2 = 4/5 of an hour

Therefore, David takes 4/5 of an hour to walk a mile.

b. Jeanette walked 1/2 a mile in a 1/10 an hour

This implies that:

(1 / 2) * 2 = 2/2 = 1 mile

(1 / 10) * 2 = 2 / 10 = 1/5 of an hour

Therefore, Jeanette takes 1/5 of an hour to walk a mile.

c. Kay walked 1/5 a mile 1/2 a hour

This implies that:

(1 / 5) * 5 = 5/5 = 1 mile

(1 / 2) * 5 = 5 / 2 = 2.5 hours

Therefore, Kay takes 2.5 hours to walk a mile.

d. Mark walked 1/3 a mile in 3/5 an hour

This implies that:

(1 / 3) * 3 = 3/3 = 1 mile

(3 / 5) * 3 = (3 * 3) / 5 = 9 / 5 = 1.8 hours

Therefore, Kay takes 1.8 hours to walk a mile.

Conclusion.

Based on the calculations above, only Jeanette is walking at the same rate as Caroline. This is because Jeanette also takes 1/5 of an hour to walk a mile.

Answer:

x = 2 and y = 7

Step-by-step explanation:

We are given two equations:

1.      8x + y = 23

2. −10x  - y = −27

By adding both equations with each other we get:

(1.+2.) -2x = -4

Which can be reduced to:

(1.+2. : (-2)) x = 2

We can insert x in Equation 1. (or 2) and get:

8*2 + y = 23

16 + y = 23         [-16 on both sides]

y = 7

Resulting in x = 2 and y = 7 as a possible solution for this system.

Answer:

Step-by-step explanation:

8x + y = 23

-10x - y = -27

-2x = -4

x = 2

8(2) + y = 23

16 + y = 23

y = 7

Answer:

it is easy just look closely

Step-by-step explanation:

Answer:

(f o g )(x) = {8, 3), (-1, 8), (2, -1)}

Step-by-step explanation:

(f o g)(x) = [f(g(x)]

g(8) = 2 and f(2) = 3  

g(-1) = 4  and f(4) = 8

g(2) = 7 and  f(7) = -1

So, (f o g )(x) = {8, 3), (-1, 8), (2, -1)}

(f ◦ g)(x) does not exist since no input in f(x) produces an output in g(x) that can be fed back into f(x).

A function is defined as the expression that set up the relationship between the dependent variable and the independent variable.

To find (f ◦ g)(x), we need to apply g(x) to each input in f(x), and then apply f(x) to the resulting outputs from g(x).

First, let's apply g(x) to each input in f(x):

g(2) = 3 (from (2,3) in f(x))

g(4) = 8 (from (4,8) in f(x))

g(7) = -1 (from (7,-1) in f(x))

Next, we apply f(x) to the resulting outputs from g(x):

f(3) = undefined (no input in f(x) produces an output of 3)

f(8) = undefined (no input in f(x) produces an output of 8)

f(-1) = undefined (no input in f(x) produces an output of -1)

Therefore, (f ◦ g)(x) does not exist since no input in f(x) produces an output in g(x) that can be fed back into f(x).

Step-by-step explanation:

Answer this by inserting a positive number between the '6x' and the '=' sign and then subtracting the same number:

x^2 + 6x + 9 - 9 = -2

Where does the "9" come from?  Take half the coefficient of x (which is 6) and square the result (obtaining 36).  Now add 36 after the "6x" and then subtract 36:

x^2 + 6x + 9 = 7

Rewrite this with a perfect square on the left side:

(x + 3)^2 = 7            Here we have successfully "completed the square."

Answer:

(2x^2+7)

Step-by-step explanation:

5x^3 * 2x^2 = 10x^5

5x^3 * 7 = 35x^3

The identity equation is; 5x³(2x² - 7)

This question will be solved with the concept of factorization which involves simplifying an algebraic equation by collecting like terms and putting it in front of a bracket with the remaining terms inside that same bracket.

The algebraic equation we are working with is;

10x⁵ - 35x³

To solve this, we will list out the factors of 10 and 35 and pick the highest common factor.

factors of 10; 1, 2, 5, 10

Factors of 35; 1, 5, 7, 35

Highest common factor is 5

Also, for the x symbol, the highest common factor is xᵃ.

Thus the factor we are bringing to the front of the bracket is 5x³

To get what will remain in the bracket, we will just divide the original terms by 5x; [tex]\frac{10x^{5} }{5x^{3}} - \frac{35x^{3}}{5x^{3}}[/tex]

This gives; 2x² - 7

Thus, The identity equation is; 5x³(2x² - 7)
