Answer: y ≥ -2 Interval Notation: [-2, ∞)
<u>Step-by-step explanation:</u>
If the domain is x ≥ 0, then plug x=0 into the given equation to find the y ≥ value.
Range: y ≥ 2(0) - 2
y ≥ 0 - 2
y ≥ -2
Answer:
it's E
Step-by-step explanation:
(5x+y)²
You expand the bracket
it gives;
(5x + y)(5x+y)
Now, multiply 5x by 5x=25x²
multiply 5x by y= 5xy
multiply y by 5x=5xy
multiply y by y=y²
Bringing into an equation it gives;
25x²+5xy+5xy+y²
=25x²+10xy+y²
2/3 is not equivalent to 1/3
2/6 is equivalent to 1/3
Answer: 1, -1
Step-by-step explanation: This is a difference of squares when factored,
(x+1)(x-1)
Let's check using FOIL(First, outside, inside, last)
x * x =x^2
1 *x =x
x * (-1) =-x
1* -1 =-1
so x^2 +x -x -1
=x^2 -1
For the 180 turn multiply the x/y by -1
4,-3 = -4,3
for the 90 turn you switch the x and the y and multiply by -1
4,-3 = 3,-4
