Your new line has to have the same slope as the green line for them to be parallel, so start off with y=-3/4x+b.
Plug in (2,4) into the new line so 2 for x and 4 for y
It should look like 4=-3/4(2)+b
-3/4x2 is -1.5
Then add 1.5 to both sides and you should get 5.5=b
Your new line is y=-3/4x+5.5 and (0,5.5) is a point on the line
After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9
2-9= -7
therefore, f(x)= -7
if x=1, then the f(x) must be Y
<u><em>therefore, your answer should be y= -7</em></u>
Answer:
0.8
Step-by-step explanation:
The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...
factor = (year 1 population)/(year 0 population) = 320/400
factor = 0.8
Answer: x=7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−(12+4x)=−40
−4x+−12=−40(Distribute)
−4x−12=−40
Step 2: Add 12 to both sides.
−4x−12+12=−40+12
−4x=−28
Step 3: Divide both sides by -4.
−4x
−4
=
−28
−4
