No you do not. I think I will help.
Answer:
x=-2, y=8. (-2, 8).
Step-by-step explanation:
8x+5y=24
y=-4x
----------------
8x+5(-4x)=24
8x-20x=24
-12x=24
x=24/-12
x=-2
y=-4(-2)=8
Answer:
they are congruent.
Step-by-step explanation:
just move A down to -1 and and you can see they are the same.
Ik one for sure is a horizontal asmym which is 3
Answer:
y = 3/4( x+5)( x+4) ( x-1)
Step-by-step explanation:
The formula for the polynomial is
y = c( x- a1)( x- a2) ( x-a3) where c is a constant and a1,a2,a3 are the zeros
We have zeros -5,-4 and 1
y = c( x- -5)( x- -4) ( x-1)
y = c( x+5)( x+4) ( x-1)
We have a y intercept of -15
That means x=0 and y = -15
-15 = c ( 0+5)( 0+4) ( 0-1)
-15 = c( 5) ( 4) (-1)
-15 = c( -20)
Divide each side by -20
-15/-20 = c
3/4 =c
The equation is
y = 3/4( x+5)( x+4) ( x-1)
