b = -c/x - a x

Step-by-step explanation:

Solve for b:

c + b x + a x^2 = 0

Subtract c + a x^2 from both sides:

b x = -c - a x^2

Divide both sides by x:

b = -c/x - a x

B=-2

Step-by-step explanation:

Put the point (0,1) in the equation you will get:

1=c, so now equation looks like

y=ax^2+bx+1.

Put now 2nd point (1,2) you get

2=a+b+1, i.e,

a+b=1(1)

Now put 3th point (2,9) you have;

9=4a+2b+1, i.e

4=2a+b(2)

Now (2)-(1) we have

a=3, so b=-2.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
