Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.
Solution:
<u>Note that:</u>
<u>Using the clue above, let's solve each problem.</u>
- 10 mL = 10/1,000 L = 0.01 L
- 1.2 L = 1.2 x 1,000 mL = 1,200 mL
- 3,500 mL = 3,500/1,000 L = 3.5 L
- 4 L = 4 x 1,000 mL = 4,000 mL
- 230 mL = 230/1,000 L = 0.23 L
- 6.21 L = 6.21 x 1,000 mL = 6,210 mL
Hoped this helped!
Answer:
Step-by-step explanation:
radius = diameter / 2 = 5/2 = 2.5 in
V = radius^2 x pI x height = 2.5^2 x pi x 8 = 157.1 in^3 (round to the nearest tenth)
cups = Volume of a can / Volume of a cup = 157.1 / 14.44 = 10.9 (round to the nearest tenth)
12.5 gallons..............
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
