q=50-0.4d, where q is the number of quarters and d is the number of dimes in a pile of coins worth 12.50. If the input is 1 what is the output

answer: i guess 5 units?

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

i dont know what you want me to answer for this but im guessing 2: 11?
