What you have so far is correct.

Problem 7 is a function because none of the x values repeat. Each x input goes to exactly one y output. The y values can repeat. If the y values repeat, then we don't have a one-to-one function.

In contrast, problem 8 is not a function. We have x = 1 go to y = 8 and y = 6 at the same time. This is one example showing we don't have one output for a given input.

the ratio of the measure of the three sides of a triangle 9:6:5. its perimeter is 100 inches. find the measure of each side.

aniked [119]

Answer:

45 in, 30 in and 25 in

Step-by-step explanation:

Add the parts of the ratio : 9 + 6 + 5 = 20 parts

Divide the perimeter by 20 to find one part of the ratio.

$\frac{100}{20}$ = 5 ← 1 part of the ratio

9 parts = 9 × 5 = 45

6 parts = 6 × 5 = 30

5 parts = 5 × 5 = 25

45 inches, 30 inches and 25 inches are the measures of each side
