Answer:
61.2 degrees
Step-by-step explanation:
You want to isolate x on one side of the equation and the numbers on the other side
3x + 2x + 27 = 180
3x + 2x +27 - 27 = 180-27
5x = 153
x = 153/5
x = 30.6
<DOC = 2x
2x = 30.6 x 2
61.2 degrees
Answer:
2.4 i am pretty sure
Step-by-step explanation:
you just have to work backwards
Hi
(6x-5) (2x-1) = 12x²-6x-10x+5 = 12x²-16x +5
Answer:
The equation you are given is a quadratic. The standard form of a quadratic is y = a(x-h)2 + k where (h,k) is the vertex of the graph, which is a parabola. Vertically moving the graph 4 units upward means that you are moving k +4 units.
y = a(x-h)2 + k standard form
y = 5x2 - 4 original equation
y = 5(x-0)2 - 4 re-written in standard form
h = 0 k = -4
Four (4) units up is k + 4--->-4 + 4 = 0.
Therefore, f(x) = 5x2 + 0--->f(x) = 5x2.
