Carla earns $13 an hour cleaning house. How much will she earn if she works from 8:00 to 2:00?

Answer:

Yes

Step-by-step explanation:

The two angles that are both acute (B and C in this case) add up to 90 degrees. That's because a right triangle has 1 angle that = 90 and every triangle has 180 degrees.

<B + <C + 90 = 180

<B + <C = 180 - 90

<B + <C = 90

Equation

2x + 15 + 5x - 2 = 90       Collect like terms

Solution

7x + 13 = 90                      Subtract 13 from both sides

7x = 90 - 13                       Subtract

7x = 77                               Divide by 7

x = 77/7                              Divide

x = 11                                  Substitute

<B

<B  = 2x + 15

<B = 2*11 + 15

<B = 37  which makes your answer right

B. Is correct

37°

Answer:

The Slope is -5/2

Y-intercept is -25

The equation is y=(-5/2)x-25

Step-by-step explanation:

Choose a first point and a second point

Remember points are (x,y)

Use (y₂ - y₁)/(x₂ - x₁)

y-intercept: The initial value of a linear relationship, the place that a linear equation crosses the y axis, represented by the letter b, the point (0,b).

Linear Relationship -the equation that represents a straight line often represented by y=mx+b where m is the slope and b is the y-intercept.
