Answer:
D. 31
Step-by-step explanation:
First we need to find what the value of f(2) is, so we are going to substitute x for 2 in f():
f(2)=4(2)^3-10
= 4(8)-10
= 32-10
= 22
And then we substitute 22 for x in g()
g(22)= (3(22)-4)/2
= (66 -4)/2
= 62/2
= 31
the numbers are 6 and 13
let x be one of the numbers then the other is 2x + 1
their sum increased by 7 = 26
x + 2x + 1 + 7 = 26
3x + 8 = 26
subtract 8 from both sides
3x = 26 - 8 = 18
divide both sides by 3
x = = 6
the numbers are 6 and (2 × 6) + 1 = 12 + 1 = 13
