Answer:
7x+3
Step-by-step explanation:
The only like terms are 5x and 2x
5+2=7
Ew. Composition of functions. Ok, f(g(x)) is what that fancy notation means. So, you would take g(x) & substitute that into wherever x is in f(x).
So we get something crazy like
f(x)= 4 - (.5x - 2)^2
Now, we foil out the squared quantity:
f(x)= 4 - (.25x^2 - x - x + 4)
Can you believe they call that simplification?
f(x)= 4 - .25x^2 + 2x -4
Almost there...
f(x)= -.25x^2 + 2x
Hope this helps!
Answer:
Brackets always means multiply, you multiply the power and the 4 with the number power outside
That gives you 16v^18
Step-by-step explanation:
➖➖➖➖➖➖
10x^2 - 4x = 0
2x ( 5x - 2 ) = 0
x = [ 0 + 2 / 5 ]
x = 0 , 2/5 // ✔️
