Serhud [2]

Answer:

Nina sold 24 Amazebars  Plz Mark Brainliest

Step-by-step explanation:

  Cost:

80 x 0.40 = 32

180x 0.30 = 54

40 x 0 = 0

Total = 86

Income

80 x 2.25 = 180

180 x 2.25 = 405

X x 2.25 = 2.25x

Total = 585 + 2.25x

How many did she sell:

553 = 585 - 86 + 2.25x

553 = 499 + 2.25x

553 - 499 = 2.25x

54 = 2.25x

54/2.25 = x

24 = x

Find the value of n so that the line perpendicular to y = (-1/4)x-1 passes through the points (n, 3) and (4,11).
Tresset [83]

Answer:

2

Step-by-step explanation:

You'll need to find the reciprocal of m. -1/4 is your is your m and when you find the reciprocal you flip the number to 4/1 or 4 and change the negative to a positive. Then graph (4,11), you don't need to worry about your y intercept, b, or -1. On your graph go down 4 and over one to the left because it's positive the line should be going like " / "  <-- that. Keep going down until your y is three and whatever your x is, is your answer. Ex: (4,11) (3,7) (<u>2</u>,3). Hopefully, you understand :)
