Answer:
Step-by-step explanation:
W(-4,-10) lies on third quadrant.
M(-12,0) lies on second quadrant or can say in x axis
C(8,3) lies on first quadrant.
K(11,-5) lies on fourth quadrant.
9 because like I don’t even know what I’m doing with my life
Answer:
8
Step-by-step explanation:
![\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D%20%2B%5Cfrac%7B3%7D%7B8%7D)
× 8
= 3
In algebra:
× y = 3
y = 3 ÷ ![\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D)
y = 8
In the form y=ax^2+bx+c
the x value of the vertex is -b/2a
the x intercept is where th e linecrosses the x axis or where y=0
expand
(x+4)(x+2)=x^2+6x+8
a=1
b=6
x value of vertex=-6/2(1)=-6/2=-3
sub back to find y value
(-3)^2+6(-3)+8
9-18+8
-1
y value is -1
vertex is (-3,-1)
x intercept
set to zero
0=(x+4)(x+2)
set each to zero
0=x+4
-4=x
x+2=0
x=-2
x intercept are at (-4,0) and (-2,0)
vertex is (-3,-1)
x ints are at (-4,0) and (-2,0)
