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
Answer:
A. 13, 10, 16
Step-by-step explanation:
If three sides of triangle have measures a, b and c, then
Check all options:
A. a=13, b=10, c=16
Thus,
This option is true
B. a=1, b=2, c=3
Then
but 
must be greater than c, so
this option is false
C. a=5.2, b=11, c=4.9
Then
but 
must be greater than b, so
this option is false
D. a=208, b=9, c=219
Then
but must be greater than c, so
this option is false
Answer:

You can do Guess and Check(but the smart way). You first get 102 and 12. Then, you can minus 3 from each one of them, getting 99 and 9, also being 11 times the other, so then the answer would be 180 - 99 or 90 - 9, equaling 81
