Which ordered pies could be points on a line parallel to the line that contains (3,4)and(-2,2) check all that apply
svlad2 [7]
  • Slope formula: \frac{y_2-y_1}{x_2-x_1}

So lines that are parallel will have the same slope. So the answer we are looking for will have the same slope as the line containing points (3,4) and (-2,2). Use the slope formula to determine which of these points have the same slope.

<h3>Original Line:</h3>

\frac{4-2}{3-(-2)}=\frac{2}{5}

<u><em>Lines that are parallel to this line will have a slope of 2/5</em></u>

<h3>Option A:</h3>

\frac{-5-(-3)}{-2-(-7)}=-\frac{2}{5}

<h3>Option B:</h3>

\frac{1-(-1)}{-1-(-6)}=\frac{2}{5}

<h3>Option C:</h3>

\frac{5-0}{2-0}=\frac{5}{2}

<h3>Option D:</h3>

\frac{2-0}{8-3}=\frac{2}{5}

<h2><u>Results:</u></h2>

Since the only options that had a slope of 2/5 was options B and D, <u>B and D are your answers.</u>

Suppose water flows from a shower at a rate of 0.35 cubic feet per minute. do you use more water by taking a 15-minute shower or
timurjin [86]

Unit conversion is a way of converting some common units into another without changing their real value. The option in which more water will be used is by filling a bathtub.

<h3>Units conversion</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given water flows from a shower at a rate of 0.35 cubic feet per minute. Therefore, the water that will be used in the shower,

Water used in Shower = 0.35 × 15 = 5.25 cubic feets

Water used in bathtub = 0.5 yards³ = 13.5 cubic feets

Hence, the option in which more water will be used is by filling a bathtub.
