Let f(x) = -3x + 2 and g(x) - 4x + 6. Find (f•g)(-5).
mezya [45]

Answer:

(f•g)(-5) = -238

Step-by-step explanation:

We have that:

f(x) = -3x + 2

g(x) = 4x + 6

Find (f•g)(-5).

First we find (f.g)(x)

So

f(x)*g(x) = (-3x + 2)*(4x + 6) = -12x² -10x + 12

When x = -5

-12(-5)² - 10(-5) + 12 = -238

(f•g)(-5) = -238

Melissa has three different positive integers. She adds their reciprocals together and gets a sum of $1$. What is the product of
Whitepunk [10]

If the three integers are a,b,c, then we have

\dfrac1a+\dfrac1b+\dfrac1c=1

We can combine the fractions on the left side:

\dfrac{bc}{abc}+\dfrac{ac}{abc}+\dfrac{ab}{abc}=\dfrac{bc+ac+ab}{abc}=1

\implies abc=bc+ac+ab
