Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1
Answer:
=−3x+42
Step-by-step explanation:
Let's simplify step-by-step.
−4(x−7)+x+14
Distribute:
=(−4)(x)+(−4)(−7)+x+14
=−4x+28+x+14
Combine Like Terms:
=−4x+28+x+14
=(−4x+x)+(28+14)
=−3x+42
The answer is a enlargement
Answer:
infinite number
Step-by-step explanation:
Carry out the multiplication indicated here:
5x + 3(x-5) = 6x + 2x -15 => 5x + 3x - 15 = 6x + 2x -15
Now combine the x terms: We get 8x - 15 = 8x - 15, or -15 = -15.
This last result is always true, so this equation has an infinite number of solutions.
