Answer:
g(x) = f(x) + 2
Step-by-step explanation:
To move the two to the other side of the equation, you have to add the two to both sides of the equation. The 2 cancels out on the g(x) side, and a 2 is added to the f(x) side.
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
Ava's mother is 36, A+3A+2(3A)=120. 12+36+72=120. A=12. The smallest number is 12.5, X+(X+4)+2x=54. 12.5+16.5+25=54 :)
You could set up the equation as X^2=4X (3), and then simplify the equation to X^2 =12X, you can divide X from both sides, leaving you with X=12
