Answer:
C
Step-by-step explanation:
3/4 of 1000 is 750 and 1/5 of 750 is 150 so your answer is C
1a. The equation is x-35+x+5+x
<h3><u>
Answer:</u></h3>
Option: D
Horizontal stretching.
<h3><u>
Step-by-step explanation:</u></h3>
We have to find the effect on the graph of the function f(x)=2x when it is replaced by f(0.5 x).
We know that when a parent function f(x) is replaced by f(kx) then either the graph is stretched horizontally or shrinked horizontally.
if k>1 then the graph is shrinked horizontally.
if k<1 then the graph is stretched horizontally.
Hence here k=0.5<1 so the graph of the function is stretched horizontally.
we are given

Since, we have to solve for b

so, we will isolate b ony one side
so, we will add 60 on both sides



so,
Answer:
Maureen should have added 60 to both sides.
