Answer:
43. <u>(2) $2.00</u>
Step-by-step explanation:
<u>Question 43</u>
- Let cheese pizza be c and mushroom pizza be m
- 3c + 4m = 12.50
- 3c + 2m = 8.50
Subtract Equation 2 from Equation 1.
- 3c + 4m - 3c - 2m = 12.50 - 8.50
- 2m = 4.00
- m = $2.00
- <u>(2) $2.00</u>

<h3>Given</h3>
<h3>Find</h3>
- write the linear function f(x)
<h3>Solution</h3>
A linear function is the equation of a line. Here, you are given two points on the line, one of which is the y-intercept, and asked to write the equation. It can work reasonably well to use the 2-point form of the equation of a line.
For points (x1, y1) and (x2, y2), the equation of the line through them can be written as
... y = (y2 -y1)/(x2 -x1)·(x -x1) + y1
When it is possible to use x1 = 0, this is simplified somewhat, so we choose
... (x1, y1) = (0, -5) . . . . . . from f(0) = -5
... (x2, y2) = (5, -1) . . . . . .from f(5) = -1
Putting these values in the above formula, we get ...
... y = (-1 -(-5))/(5 - 0)·(x -0) -5
... y = 4/5x -5 . . . . . simplified
This can be put in the desired functional form using f(x) instead of y:
... f(x) = 4/5x -5
