Find the missing coefficients y=ax^2-10x+c vertex :(-5,20)

Citrus2011 [14]

Remember, for $y=ax^2+bx+c$ the x value of the vertex is $\frac{-b}{2a}$

so
given
x value of vertex is -5
and
$y=ax^2-10x+c$
$\frac{-b}{2a}=\frac{-(-10)}{2a}=\frac{10}{2a}=$
$\frac{5}{a}=-5$
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1

$y=-1x^2-10x+c$
comlete the square
remember if we do
$y=a(x-h)^2+k$ (h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand

$y=-1(x-(-5))^2+20$
$y=-1(x+5)^2+20$
$y=-1(x^2+10x+25)+20$
$y=-1x^2-10x-25+20$
$y=-1x^2-10x-5$

a=-1
c=-5

hi, how is ur day! i need help on figuring out how to solve a Combine like terms to create an equivalent expression problem. can

Alenkasestr [34]

Step-by-step explanation:

to combine like terms you take things with either the same varibales or values

so 2y +4x-3y+8x+2y= 25

you combine the y's so 2-3=-1+2 =1

then x 4+8=12

so y+12x= 25

does that help?
