What the answer for 1/4 x 12

coldgirl [10]

Treat 12 as 12/1 that means 12 divided into 1 part
1/4 times 12/1

multiply the top and the bottom becuase

$\frac{x}{y}$ times $\frac{z}{t}$ = $\frac{x times z}{y times t}$ so

1/4 times 12/1=(1 times 12)/(4 times 1)=12/4=3/1=3

Answer:

f(-5) = 4(-5) + 1 = -20 + 1 = -19

f(-1) = 4(-1) + 1 = -4 + 1 = -3

f(2) = 4(2) + 1 = 8 + 1 = 9

f(3) = 4(3) + 1 = 12 + 1 = 13

f(5) = 4(5) + 1 = 20 + 1 = 21
