Find the value of this expression if x = 9.
x2 + 9
x+1

244

Step-by-step explanation:

x=9 9 x 2 =18 +9 =27 x 9 = 243 +1 = 244

x2+9= 27

9+1=10

Step-by-step explanation:

Since x=9 then simply just substitute the 9 in the x spot.

Also, remember that when a variable is alone, is automatically equals 1, unless told differently, like now.

9×2+9

9+1

it has the same slope and a different y-intercept

hope this : )
