The slope is -1

Step-by-step explanation:

We need two points on the line to find the slope

(0,4) and (4,0)

The slope is

m = (y2-y1)/(x2-x1)

   = (0-4)/(4-0)

  = -4/4

  = -1

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
