Answers

Answer:

Step-by-step explanation:

4x=-x+10

5x=10

Then, we divide each side by 5 to get x by itself.

x=2

For each diagram, decide if y is an increase or a decrease of x. Then determine the
percentage.
A
у
B
у

Answers

Answer:

A: Decrease, y is 80% of x

B: Increase, y is 160%of x

Step-by-step explanation:

It sounds like it wants to know what percent Y is of X, so if y was 50% of x, that would mean y was half as much of x. so if x was 10 and y was 5

A:  x is 5 and y is 4  since y is less it is a decrease.  to find the percent do 100*y/x, so in this case that's 100*4/5 =80, so y is 80% of x.  and it makes sense it is less than 100% since x is less than y

B: x=5 and y=8  y is greater than x so it is an increase and will be more than 100%.  100*8/5 = 160 so y is 160% of x
