Answer:
4
Step-by-step explanation:
We know the other side of the rectangle is 18.
So 18=10+2x
subtract 10
8=2x
divide by 2
x=4
Cross mutiply. 42*10= 420. 14*g= 14g
14g= 420
divide by 14 for both sides
14g/14= 420/14
g= 30
Check answer by using substitution method
42/30. Divide by 3 . 42/3= 14 , 30/3= 10
14/10 and 14/10 equal to each other by dividing 2.
14/2= 7 , 10/2= 5
7/5= 7/5
Answer: g= 30
Answer:
C
Step-by-step explanation:
Since the vertex is 2,1, that's the only equation that works for it. The 2 has to be the opposite, so -2, and the 1 stays 1.
First, find the value of g(x) at x=4: it's 3.
Next, use this result, 3, as the input to f(x): f(3) = 1
So f(g(4)) = 1.
