Factor and find the zeros: 3x^2+33x= -30

Add 30 to both sides: 3x^2+33x+30=0

Divide both sides by 3: x^2+11x+10=0

Factor / Complete the square: (x+10)(x+1)=0

Zero Product Property Rule: x+10=0 and x+1=0, x=-10 and x=-1

So the zeroes of the quadratic are -10 and -1

Hope this helped!

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

do i do it on a graph?
