Is this for a online final if it is I can’t help
Good for them ! They worked with things that are related to math
and arithmetic, they had some fun, and they learned something.
Much better than just fishing for answers on some boring website.
Answer:
c = -3
Step-by-step explanation:
Call the unknown c
c(x-3) +2x = -(x-5) +4
Distribute the negative sign
c(x-3) +2x = -x+5+4
Combine like terms
c(x-3) +2x = -x +9
Subtract 2x from each side
c(x-3) +2x-2x = -x-2x +9
c(x-3) = -3x+9
Factor a -3 from the right side
c(x-3) = -3(x-3)
Divide by (x-3)
c = -3
The right and left hand side need to be equal for there to be infinite solutions, so c = -3
None of these equations fit this line. The line is y = -1/4x
In order to find this, use the slope formula and two points. Two points that are on the line are (0, 0) and (4, -1).
m(slope) = (y2 - y1)/(x2 - x1)
m = (-1 - 0)/(4 - 0)
m = -1/4
