Answer:

x = 6

Step-by-step explanation:

Please write this as y = x^2 - 12x + 7 to indicate the exponentiation.

The coefficients of these three terms are a, b and c: 1, -12 and 7.

The equation of the axis (line) of symmetry is

-b -(-12)

x = --------- = ----------- = 6

What is y=29/5× answer

hram777 [196]

Answer: y=5+4/5

Step-by-step explanation:

1) Move all terms to the left:

y-(29/5)=0

2) Add all the numbers together, and all the variables

y-(+29/5)=0

3) Get rid of parentheses

y-29/5=0

4) Multiply all the terms by the denominator

y*5-29=0

5) Multiply elements

5y-29=0

6) Move all terms containing y to the left, all other terms to the right

5y=29

y=29/5

y=5+4/5
