The mathematical functions (equations) are matched to their graph line respectively as follows:
- y = 960 - 78x: purple straight line.
- y = 8·3^x: violet line curve that slopes to the left.
- y = 960·(1/2)^x: green line curve that slopes to the right.
<h3>What is a linear function?</h3>
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate. Mathematically, a linear function is given by this equation:
y = mx ± c.
<h3>What is an exponential function?</h3>
An exponential function can be defined as a type of mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:
f(x) = keˣ
Next, we would match each of the mathematical functions (equations) to their graph line respectively as follows:
- y = 960 - 78x: purple straight line.
- y = 8·3^x: violet line curve that slopes to the left.
- y = 960·(1/2)^x: green line curve that slopes to the right.

This is from simple math knowledge of lines, segments and points. From the given data, pr and rs are line segments in the line ps. Thus, we add segments pr and rs together to solve for the line ps.
pr + rs = ps
4x - 2 + 3x - 5
(Add like terms) = 7x -7
(Further simplify) = 7(x-1)
Therefore, the final answer or expression of ps = 7(x-1).

Answer:
$81
Step-by-step explanation:
The garden is 4 yards = 12 feet by 3 yards = 9 feet. The area of it is the product of these dimensions, ...
(12 ft)(9 ft) = 108 ft²
The cost of fertilizer for that area will be ...
($0.75/ft²)(108 ft²) = $81.00
They will spend $81.00 to fertilize the garden.
