Step-by-step explanation:
METHOD 1:
METHOD 2:
METHOD 3:
G(-2) means "evaluate the equation at -2"; it's asking you to swap out the "x" in the equation and sub in -2.
g(x) = x² + 3x - 2 ... plug in -2
g(-2) = (-2)² + 3(-2) - 2 ... simplify
g(-2) = 4 + (-6) - 2 ... add/subtract
g(-2) = -4
Answer:
C. x + 5 = (x + 5) − 5, which has no solution
Step-by-step explanation:
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = ( x + 5 ) -5
