Answer:
32
Step-by-step explanation:
I hope that those brackets mean the absolute value, which means that you will make both 26 and 19 positive, then adding which gives you 45 and then subtract 13, giving you 32.
Answer:
(3,3)
(-5,19)
Step-by-step explanation:
y= x^2 - 6
y=-2x + 9
Set the two equations equal to each other y=y
x^2 - 6 =-2x + 9
Add 2x to each side
x^2 +2x- 6 =-2x+2x + 9
x^2 +2x- 6 = 9
Subtract 9 from each side
x^2 +2x- 6-9 =9- 9
x^2 +2x- 15 =0
Factor the left hand side
What 2 numbers multiply to -15 and add to 2
-3 *5 = -15
-3+5 = 2
(x-3) (x+5) =0
Using the zero product property
x-3 =0 x+5 =0
x=3 x=-5
Now we find y for each x
x=3
y=-2(3) + 9 = -6+9 =3
(3,3)
x=-5
y=-2(-5) + 9 = 10+9 =19
(-5,19)
