Answer:
She needs to get 27/30 right.
Step-by-step explanation:
Part a)
16 x - 10
f + g = 5x − 12 + 11x + 2= 16x -10
Part b)
f * g = (5x − 12)(11x + 2) = 55x^2 - 132x + 10x - 24 = 55 x^2 - 122 x - 24
<span>Part c) </span>
<span>f(g(x)) = f( 11x + 2) = 5(11x +2) - 12 = 55x + 10 - 12 = 55x-2
</span>
Answer:
<em><u>x = -0.5</u></em><em> </em>
Step-by-step explanation:
<em>You need to combine like terms</em>
x * 2 + 5x = -6
<em>Add x to 5x</em>
6x * 2 = -6
<em>Divide 2 from both sides</em>
6x = -3
<em>Divide 6 from both sides to get x alone</em>
x = -0.5
<em>Hope this helps</em>
