Answer:
percentage change=25% .
Step-by-step explanation:
Given : $15.60 to $11.70 .
To find: What is the percent change .
Solution: We have given that $15.60 to $11.70 .
Change = final value - initial value .
Change = $15.60 - $11.70
=$3.9
percentage change = 
= 
= 
.
On dividing both number by 3
percentage change=
.
percentage change=
.
percentage change=25% .
Therefore, percentage change=25% .
Answer:
y=-5
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are equal and bisect each other
so
step 1
Find the value of x
substitute the given values
solve for x
Multiply by 2 both sides
step 2
Find the value of y
we have
substitute
substitute the value of x
Answer:
540 is the answer i think
Answer:
A
Step-by-step explanation:
I think a) would be the answer. I proceeded by elimination: the domaine of the function goes from 3 and continues to infinity, so that leaves with a) and b) as possible answers. Both have the same range and both of their functions reflect over the x axis, so we have to compare the two answer by looking at the position of the function in the graph. The function is in the first quadrant (top right corner), so the position of the function has to be at our right, which leads us to a).
