5-2(y+1)=21

Distribute
5-2y-2= 21

Combine like terms
3-2y=21

Subtract 3 from both sides
-2y= 18

Divide both sides by -2
y= -9

Final answer: y=-9

Please answerrrr Graph g(x), where f(x) = 4x − 2 and g(x) = f(x + 1). a line labeled g of x that passes through points 0, negati
Mrrafil [7]

Answer:

a line labeled g of x that passes through points negative 1, negative 2 and 0, 2

Step-by-step explanation:

we have

f(x)=4x-2

g(x)=f(x+1)

To determine g(x), substitute the variable x by (x+1) in the function f(x)

so

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

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

f(x+1)=4x+2

g(x)=f(x+1)

g(x)=4x+2

therefore

a line labeled g of x that passes through points negative 1, negative 2 and 0, 2
