Answer:
Please check the formatting when posting. I'm assuming these are the equations:
y=x^2 - 2
y=−x
Step-by-step explanation:
We can either graph the equations or solve them. I use graphing - see the attachment. The lines intersect at (-2, 2) and (1,-1)
<u>1. Graphing</u>
See attached graph
(-2, 2) and (1,-1) are the intersection points
<u>2. Solving</u>
y=x^2 - 2 Use y=−x in this equation:
-x = x^2 - 2
0 = x^2 + x - 2
0 = (x+2)(x-1)
x = -2 and +1
(-2, 2) and (1,-1) are the intersection points
Hey there!
The opposite of the square root of 25 is -5, and this is an <u>integer and a rational number and a real number.</u>

Hope it helps and have a great day!
Answer:
part A is crosby is correct because when u see multiplying by exponents, the exponents are gonna be added.
part B is Adam is correct because when u divide numbers by exponents its gonna be subtracting the exponents
Step-by-step explanation:
hope this helps
Given:
The given equation is:
To find:
The solution for the given equation.
Solution:
We have,
On simplification, we get
Squaring both sides, we get
Divide both sides by -2.
Therefore, the correct option is B.
