Answer:
A. 
Step-by-step explanation:
The equation in slope-intercept form,
, can be created to be used in finding Jack's pay. We need to find the slope (m) and the y-intercept (b) of the linear function.
Using two points (1, 18), and (1.5, 23), find the slope (m):
Slope (m) = 
Find b, by substituting x = 1, f(x) = 18, and m = 10 into
.


Subtract 10 from each side



Substitute m = 10 and b = 8 into
.
✅Thus, the linear function that can be used to find Jack's pay would be:

Answer:
(x - 43)(x + 3)
Step-by-step explanation:
consider the factors of the constant term (- 129) which sum to give the coefficient of the x- term (- 40)
the factors are - 43 and + 3 , since
- 43 × + 3 = - 129 and - 43 + 3 = - 40 , then
x² - 40x - 129 = (x - 43)(x + 3) ← in factored form
