Answer:
(- 2, 4 )
Step-by-step explanation:
y = 2x + 8 → (1)
y = - 2x → (2)
substitute y = 2x + 8 into (2)
2x + 8 = - 2x ( add 2x to both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
substitute x = - 2 into (2)
y = - 2(- 2) = 4
solution is (- 2, 4 )
The radius is 8, just divide by 2
X + y = -15. Subtract x from both sides.
y = -x - 15. This is as far as we can go with the provided information.
Yes
Explanation:
2x9=18 and 1+8=9
The pattern repeats
1:5=1/5
1/5=20/100
20/100= 20%
