Answer: x=-1/2
Step-by-step explanation:
8x=-4
divide by 8 on both sides
x=-1/2
Answer:
22.5°
Step-by-step explanation:
The triangle is an equal 1/8 slice of the octagon. If another triangle were placed right next to it, it would have the same angle. so to find out the angle, we just have to divide it by 2.
45 ÷ 2 = 22.5
Answer: The vertex is (-3, 2)
The equation y = -4(x + 3)^2 + 2 can be written as y = -4(x - (-3))^2 + 2
I rewrote x+3 as x - (-3)
Compare y = -4(x - (-3))^2 + 2 with the general template y = a(x-h)^2 + k
Note how
a = -4
h = -3
k = 2
So the vertex is (h,k) = (-3, 2)
⇒To get the difference we subtract.
⇒To get the sum we add.
Goodluck!!
Answer:
8
Percentile
How I solved it:
60% of 20 is 12 and therefore 20 - 12 = 8 or 40%
