The values have being matched to the variables that they represent here:
- x-variable: the number of hours Sam works at the airport
- y variable: the amount in dollars that Sam has after paying back Daniel
- 12: amount in dollars that Sam earns per hour.
- 40: the amount in dollars Sam owes Daniel
<h3>How to solve for the equation.</h3>
The equation of this form y = 12x-40
The variable y has been said to be the amount sam has after Daniel has been paid.
X is the amount that has to be multiplied by what he earns in dollars by the hour.
40 dollars is the amount that he owes which is going to be subtracted from what he earns by the hour.

Answer:
is equation of height of rocket.
Option D is correct.
Step-by-step explanation:
Given: A rocket is launched with speed 85 ft/s from a height 28 feet.
Launching a rocket follows the path of parabola. The equation of rocket should be parabolic.
Parabolic equation of rocket is
Formula: 
g ⇒ acceleration due to gravity (-32 ft/s)
v ⇒ Initial velocity (
)
h ⇒ Initial height (
)
h(t) ⇒ function of height at any time t
Substitute the given values into formula
D is correct.
Answer:
-2, C
Step-by-step explanation:
Use the formula: (y2-y1)/(x2-x1)
Substitute the numbers:
(4-(-4)) / (3-7)
=8 / -4
= -2
The slope is -2, or C
