Answer:

12i^2+38i-40

Step-by-step explanation:

In this problem, you have to FOIL.

Which means that first you multiply the first term "8" in (8+2i) by the terms in (-5+6i)

so...

8 * -5

8*6i

And you get:

-40 + 48i

Then You multiply the second term "2i" by the terms in (-5+6i)

so...

2i*-5

2i*6i

And you get:

-10 +12i^2

Then you add like terms to get: 12i^2 +38i-40

Sliva [168]

Answer: The slope is 3/2

Step-by-step explanation:

To find the slope, you need to find the difference between the y coordinates and  divide it by the difference in the x coordinates.

The y coordinates are  -4 and 5

The x coordinates are  -4 and 2

-4 -5 = - 9

-4 - 2 = -6

-9/-6 =  3/2

I need help solving this problem
Ludmilka [50]
G(f(2)) means work out whatever f(2) is then plug this into g(x).

So f(2) is 3 because we just find the x-value 2 in the left hand column and read across. This is 3.

So then we find g(3) by finding the x-value 3 in the left hand column and read across. This is 10.

So g(f(2)) = 10
