Evaluate the following relation. {(14, 12), (15, −2), (12, −5), (−2,  15)} the relation is a function a. true b. false

B. false Cuz it doesn't make sense

It's true! None of the x's and y's are repeating, it may look like it, but they're not. Therefore it is a function.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
