Step-by-step explanation:
Algebra
= 4(x + 2)
= 4 × (x + 2)
= 4 × x + 4 × 2
= 4x + 8
Answer:
If i'm thinking correctly, the correct answer should be G.
Step-by-step explanation:
We have that
y = 2x + 8
for x=1-----------> y=2*1+8=10
for x=2-----------> y=2*2+8=12
for x=3-----------> y=2*3+8=14
.
.
.
the equation y = 2x + 8 ----------- > defines y as a function of x, because <span>for each x there is only one value of y</span>.
the answer is
yes, the equation y = 2x + 8 defines y as a function of x
