Answer:
f(2)= -2
g(2)= 12
Step-by-step explanation:
To solve this we use the substitution method. Since f(2) is your variable, we will plug the x-value of 2 into each equation
f(2)= 2(2)^2-5(2)
f(2)=8-10
f(2)= -2
If the same variable is used for both equations then g(x) would be g(2) as well leaving you with
g(x) = 3x^2
g(2)= 3(2)^2
g(2)=12

Answer:
Step-by-step explanation:
First you need to get like items on the same side(put the variables on one side and the non-variables on the other). Remember anything you do on one side of the equal, you have to do on the other side, too.
5X+3=7X-1 I'm going to move the -1 first, but you don't have to as long as you keep the equation equal.
5X+3+1=7X-1+1 We know that +1-1 is zero and so is -1+1. So
5X+3+1=7X We don't need to keep that zero.
5X+4=7X Now, we want to move the 5X over.
5X-5X+4=7X-5X Simplify and get rid of the zero.
4=2X Last, we have to divide to get the 2 away from the X.
4/2=2X/2 Not everyone know that slash mean divide, :-).
2=X
