Equations:

2x+105=-3x+130

subtract 2x from both sides 

105= -5x+130

Subtract 130 from both sides

-5x= -25

isolate the variable

x=5 

Plug back in

2(5)+105= -3(5)+130

115= 115

Andrew solves 6x2=12x by using the quadratic formula. What values does he use for a, b, and c? a = (Put the number only in the b

zhenek [66]

Answer:

a=6, b=-12, and c=0

Step-by-step explanation:

The standard format for the quadratic formula is ax^2+bx+c (=0).

If we rearrange the numbers given to look like this formula, we will find the values of a, b, and c.

6x^2=12x We can move over the 12x to the other side.

6x^2-12x=0 There is no visible value of c, but since there is no term without a variable, c=0

6x^2-12x+0=0

So a=6, b=-12, and c=0
