Simplify the expressions (x-2) (3x-4)

Answers

This expression can be simplified using the FOIL method of multiplication (first, outer, inner, last).

First: x · 3x = 3x²
Outer: x · -4 = -4x
Inner: -2 · 3x = -6x
Last: -2 · -4 = 8

Combine all these terms, and it leaves you with your final answer:
3x² - 10x + 8

Given the graphs of f(x) = X - 8 and g(x) = -4x + 2, find the solution to this system of equations: Y - X = -8 and 4x + y = 2 A) (0, 2) B) (0.-8) C) (2, -6) D)

Answers

Answer

The Answer is C) 2, -6

Step-by-step explanation:

Look at the graph as you can see there is only one solution to that graph and on the line intersected there is one point which that would be 2, -6.

Note: Understand that when asking about the point or something else look for the lines intersected each other then you could find your answer. If there is only one line then it is infinite solutions but if the lines don't intersect then it is a no solution.

What are the domain and range of the relation {(–5, 5), (–3, 2), (0, 3), (3, 2)}?

Answers

domain is th set of number you input
range is the set of number you get from inputing the domain
normally domain is x and range is y
(x,y)

domain is all 1st number
range is all 2nd numbers

doman={-5,-3,0,3}
range={5,2,3} (if it repeats, don't list)
