3 To solve 2x + 9 = 21, what is the first step?
А. Dividing each side by 2
B
Dividing each side by x
С
Subtracting 21 from each side
D
Subtracting 9 from each side

D. Subtracting 9 from each side

Step-by-step explanation:

Always start with numbers without variables first before doing anything with x. And make sure one side must not equal 0 unless you're doing polynomials.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

i believe that the answer is

b. y-1=-2(x-4)

hope this !
