Answer:
The 'm' stands for slope and the 'b' stands for the y-intercept, which is where the line crosses the y-axis.
The distance between the building and the ladder is 34.876 foot.
<h3>What is a Right Triangle?</h3>
A triangle in which one of the angle measure is equal to 90 degree is called a right triangle.
The ladder forms a right triangle with the building and the ground,
The length of the triangle is 40 foot
The angle made by the ladder is 29.32 degree
By using Trigonometric Ratios
cos 29.32 = Base / Hypotenuse
cos 29.32 = Base / 40
0.8718 × 40 = Base
Base = 34.876 foot
Base is the distance between the building and the ladder.
Base of the ladder = 34.876 foot

The equation that show the relationship between Anna earning and time worked is y = 8.5h.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where m is the rate of change, b is the y intercept and y, x are variables.
Let y represent Anna earnings for working h hours.
Since she charges $8.50 per hour to babysit. Hence:
y = 8.5h
The equation that show the relationship between Anna earning and time worked is y = 8.5h.

Answer:
-7 is your answer
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.
4 + y = -3
Subtract 4 from both sides
4 (-4) + y = -3 (-4)
y = -3 - 4
y = -7
-7, or (D) is your answer
