Answer:
x would equal -11 or 13
Step-by-step Explanation:
x(x - 2) - 143 = 0
x^2 - 2x - 143 = 0
-2x + x^2 = 143
-143 + (-2x) + x^2 = 0
(x - 13)(x + 11)
x - 13 = 0
Add 13 to both sides
x = 13
x + 11 = 0
Subtract 11 from both sides
x = -11
Answer:
P = -0.004Q + 149
Step-by-step explanation:
The general form of the linear equation is:

The slope of the equation (a) can be found by using the two given points (4,000; $133) and (27,000; $41)

Applying the point (4,000; $133) to the equation below yields in the linear equation for Price as a function of the number of shirts:

The linear equation is:
P = -0.004Q + 149
Answer:
