Answer:
x = -1/4
Step-by-step explanation:
3/x = -4 - 8
3/x = -12
x= -3/12
x= -1/4
Answer:
A. vertex, (3, 0); y-intercept 4.5
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex
(
h
,
k
)
.
(
3
,
0
)
To find the x-intercept, substitute in 0 for y and solve for x
. To find the y-intercept, substitute in 0 for x and solve for y
.
x-intercept(s):
(
3
,
0
)
y-intercept(s):
(
0
,
4.5
)
Calculate Δ = b^2 -4ac => Δ = 169 => k1 = 3/2; k2 = -5 => 2k^2 + 7k - 15 = 2*(k -3/2)(k+5) = (2k - 3)(k+5);
Answer:
If we know that 2 angles are complements of each other, then they add up to 90 degrees. Knowing this, if we know that the complement of an angle X has an angle value that is 3 times greater, we can write that as such: X + 3X = 90 => 4X = 90. We solve for X to get: 22.5 degrees.
