Evaluate f(x) = -4x + 7 when x = 2 and x = -2.

f(x)=-1 and 15

Step-by-step explanation:

What you do is you put -2 and 2 into the x.

f(x) = -4(-2) + 7 = -1

f(x) = -4(2) + 7 = 15

f(x)=-1 and 15 are your answers.

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
