Let f (x) be a quadratic equation of the form:
Where b and c are real numbers.
So a generic procedure for completing squares is:
1) identify b
In this case b = 10
2) divide b between 2 and then square it
3) Add and subtract 
in the equation
4) Rewrite the equation as follows
The number that you must add to both sides of the equation is number 
Answer:
A. y = 6x -1
Step-by-step explanation:
take two coordinates: (-1,-7) , (2,11)
slope:
....slope(m)
equation:
y - y1 = m(x - x1)
y - 11 = 6(x-2)
y = 6x -12 + 11
y = 6x -1
Answer:
160 miles per hour
Step-by-step explanation:
640/4=160
960/6=160
Volume of a cube = l^3, where l is the side length (note that the length, width and height in a cube are equal)
Volume of cube = 6^3 = 216 m^3
I’m not extremely good at math but I think you need to make -x-y=1 into y=mx+b form and then solve your new equation!
