Step-by-step explanation:
Answer:
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
The ordered pairs are: (100, 135) and (500, 375)
The first number is the number of minutes of usage and the second number is the charge of the month.
The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6
Step-by-step explanation:
Answer:
(x^2 – 1) – 5(x – 1)
Step-by-step explanation:
p(x) = x^2 – 1 and q(x)=5(x-1)
(p – q)(x) = x^2 – 1 -5(x-1)
Distribute
= x^2 - 1 -5x +5
= x^2 -5x +4
