Answer:
16 I guess
Step-by-step explanation:
2*2 is 4
Then 4 times 4 is 16.
Answer:
B) x - 4
Step-by-step explanation:
In this question, you have to simplify the expression to get your answer.
Solve:
1/2(2x - 8)
Use the distributive property.
1/2(2x) + 1/2(-8)
x + 1/2(-8)
x - 4
Your answer would be B) x - 4
They are inverses if f( (g(x)) = x
f((g(x)) = (1/2) (2x + 4) - 2 = x + 2 - 2 = x
so this proves that g(x) is the inverse of f(x)
the other inverse g((f(x)) should also be = x
Answer:
y = 2x + 4
Step-by-step explanation:
Two points on this line are (-2, 0) and (0, 4). Going from the first to the second, x increases by 2 (this is the 'run') and y increases by 4 ('rise').
Thus, the slope of this line is m = rise / run = 4/2 = 2
Using the slope-intercept formula, we get y = mx + b = 2x + b
Let x = -2 and y = 0 to find b: 0 = 2(-2) + b, so b = 4, and the desired equation is then:
y = 2x + 4
