X=Juliana's age
r=Rich's age
(x+2)+(x*3)+5=R
You can solve it from there
F(x) is another way to say “y” so you could also write, y=2(x+6)-4, and it’s asking what does x equal if y is 6, so you substitute 6 for y.
6=2(x+6)-4
6=2x+12-4
6=2x+8
-2=2x
-1=x
It has a ratio of 1:4, meaning for every x, you'd get 4 from your y
Answer:
64
Step-by-step explanation:
2x × 4y
x=2 and y=4
Put x as 2, and y as 4.
2(2) × 4(4)
4 × 16
= 64
