Write an equation perpendicular to x-3y=3 passes through (5,-9)

kherson [118]

3y=x-3
y=1/3x-1
Perpendicular slope: -3
y=-3x+b
Plug in the coordinates in the equation:
-9=-3(5)+b
-9=-15+b
4=b
Equation: y=-3x+4
Also, when finding the perpendicular slope you take the reciprocal of the original slope and make it negative if it is positive and make it positive if it’s negative.

A chemist needs 2,220 ml of potassium chloride to complete an experiment. She has 2 L. How many more liters does she need?

DerKrebs [107]

Answer:

0.220 L

One liter is 1000 mL, so 2,220 mL is 2.220 L. Subtracting the 2 L on hand gives the additional amount required:

2.220 L - 2 L = 0.220 L
