If p(x)=3x, what is p(x+3)?

please hurry guys

3x+9

Step-by-step explanation:

since p(x) means p multiplied by x and the answer is 3x it means p=3 so 3(x+3) you multiply 3 by x which is 3x and 3 times 3 which is 9 so 3x+9

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10
