Answer:

A

Step-by-step explanation:

To determine which point is a solution, substitute the x- coordinate into the equation and if the value obtained agrees with the y- coordinate of the point then it is a solution.

A (- 3, - 17)

y = 4(- 3) - 5 = - 12 - 5 = - 17 ← (- 3, - 17) is a solution

B (4, 7)

y = 4(4) - 5 = 16 - 5 = 11 ≠ 7 ← not a solution

C (- 2, - 18)

y = 4(- 2) - 5 = - 8 - 5 = - 13 ≠ - 18 ← not a solution

D (3, 17)

y = 4(3) - 5 = 12 - 5 = 7 ≠ 17 ← not a solution

The number of walls, w, that Joe can paint in t hours is given by the equation w=32t−1. Answer the questions below.
klio [65]

We have been given an equation w=\frac{3}{2}t-1 that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.

To solve our given problem, we will substitute w=7 in our given equation as:

7=\frac{3}{2}t-1

Let us solve for t.

7+1=\frac{3}{2}t-1+1

8=\frac{3}{2}t

8\cdot\frac{2}{3}=\frac{2}{3}\cdot\frac{3}{2}t

\frac{8\cdot2}{3}=t

\frac{16}{3}=t

Therefore, it will take \frac{16}{3} hours Joe to paint 7 walls.

Recall that two angles are complementary if the sum of their measures is 90°. Find the measures of two complementary angles if o
nirvana33 [79]

Answer:

The two angles are 69° and 21°.

Step-by-step explanation:

Write out the expression:

let x and y be two angles that are complementary and the sum of their measures is 90°

-> x° + y° = 90°

if one angle is 6º more than three times the other angle:

-> x° = 6° +3y°

Plug x = 6+3y into x° + y° = 90°

6° + 3y° + y° = 90°

Solve for y

4y° = 84°

y° = 21°

Plug y into x° + y° = 90°

x° + 21° = 90°

Solve for x°

x° = 90° - 21° = 69°
