Answer:

-22

Step-by-step explanation:

The function y=400-22x is a linear equation in the form y=mx + b. Although they put "mx" after "b" so the equation doesn't start with a negative.

"m" is rate of change, or the slope if graphed.

The negative means "y" decreases as "x" increases. On a graph, it decreases left to right.

Answer:

5−x²+2xy−y²

Step-by-step explanation:

5 - (x-y)²

Rewrite

(x−y)² as (x−y)(x−y) so

5−((x−y)(x−y))

Expand (x−y)(x−y) using the FOIL Method

Apply the distributive property.

5−(x(x−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−yx−y(−y))

Simplify and combine like terms

Simplify each term

5−(x²−xy−yx+y²)

Subtract yx from −xy

5−(x²−2xy+y²)

Apply the distributive property

5−x²−(−2xy)−y²

Multiply −2 by −1

5−x²+2xy−y²

Solve for x. Your answer must be simplified. -36 + X < 8

KIM [24]

First, you add 36 to both sides to get rid of -36. Then, the right side turns to 44 when add 8 and 36 together. Finally, your final answer is x<44

If f(x)=3^x+10x and g(x)=4x-2, find (f+g)(x)

Vikentia [17]

Hi there!

First we need to remember the following.
$(f + g)(x) = f(x) + g(x)$

Now substitute both of the formulas.
$(f + g)(x) = ({3}^{x} + 10x)+ (4x - 2)$

Work out the parenthesis.
$(f + g)(x) = {3}^{x} + 10x + 4x - 2$

And finally collect terms.
$(f + g)(x) = {3}^{x} + 14x - 2$

~ Hope this helps you!
