Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The parabola vertex point is always (h, k) in y = (x-h)^2 + k
All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
Answer:
18
Step-by-step explanation:
x-5=(x+8)/2
x-5=x/2+4
add 5
x=x/2+9
subtract x/2
x/2=9
times 2
x=18
0.70 is the answer because 0.70=70 tenths.
We know that a = b and c = 30
Since b + 30 = 90, we know b = 60.
That means a = 60
a = 60
b = 60
c = 30
