Parallel lines are lines that exist in the same plane and never cross. In order to not cross, their slopes must be the same.
The line given is in slope-intercept form
y = mx + b
Where m is the slope and b is the y-intercept. Therefore the slope of the line y = 5x - 5 is 5.
Any line with a slope of 5 will be parallel.
For example, y = 5x + 1
Answer:
the last one

Answer:
$9.75
Step-by-step explanation:
I divided $78 by 8 people and that is how I got this answer.
You know 1 is not a root because the sum of the coeffcients of the equation is 14, not zero.
It is fairly easy to try 3 by synthetic division (see attachment), which tells you that 3 is a root and the remaining quadratic factor is x²-3x-5. The quadratic formula tells you the roots of that factor are
... x = (-b±√(b²-4ac))/(2a) = (3±√29)/2
The appropriate choices are
... C. (3-√29)/2
... D. (3+√29)/2
... F. 3
_____
The quadratic formula tells you the solution to
... ax²+bx+c=0
is x = (-b±√(b²-4ac))/(2a)
We have a=1, b=-3, c=-5.
Answer:
500
Step-by-step explanation:
Subtract 450 from both sides 25c=12500 so c=500
