Answer:
There is nothing, thats your answer
Step-by-step explanation:
Answer:
5x^2 +8x-4
Step-by-step explanation:
(5x - 2) * (x + 2)
We can FOIL
first: 5x*x = 5x^2
outer : 2*5x = 10x
inner: -2x
last : -2*2 = -4
Add these together
5x^2 +10x-2x-4
5x^2 +8x-4
The answer is A
Domain: (0, infinity)
Range: ( - infinity, infinity)
Answer:
<em>x </em>= -2
<em>y </em>= 0
Step-by-step explanation:
Pretty hard process, but let me explain:
First, solve for y.
Substitute -x - 2 for y in x - y = -2:
Then, simplify both sides of the equation.
x - y = -2
x - (-x - 2) = -2
After, add -2 to both sides of the equation.
2x + 2 = -2
2x + 2 + -2 = -2 + -2
Next, divided both sides by 2.
2x/2 = -4/2
After that, substitute -2 for x in y = -x - 2:
You must simplify both sides of the equation.
y = -x - 2
y = -(-2) - 2
y = 0
Sorry if this is long and confusing, but I hope this helps!!
I think the answer is 8, not sure though
