Two buses leave a station at the same time and travel in opposite directions. One bus travels 14 kmh slower than the other. If t

alisha [4.7K]

Answer:

106 km / hour

Step-by-step explanation:

Givens

Total time: 6 hours

Total distance: 1356 km

First bus rate: r

Second bus rate: r - 14

Formula

d = r * t

Solution

r*6 + (r - 14)*6 = 1356 Remove the brackets

6*r + 6*r - 84 = 1356 Add like terms

12r - 84 = 1356 Add 84 to both sides

12r + 84 - 84 = 1356-84 Combine

12r = 1272 Divide by 12

r = 1272/12

r = 106 km/hr

What is the slope of a line parallel to the line with equation 5x + 3y = 7?

weeeeeb [17]

Answer:

-5/3

Step-by-step explanation:

Parallel lines are lines which have the exact same slope but different y-intercepts. We can find the slope by converting to slope-intercept form, y=mx+b from standard form.

We convert by using inverse operations to isolate y.

5x+3y=7

5x-5x+3y=7-5x

0x+3y=-5x+7

3y=-5x+7

$\frac{3y}{3} =\frac{-5x+7}{3} \\y=\frac{-5}{3}x+\frac{7}{3}$ .

The slope is -5/3. SInce parallel lines have the same slope, the slope for a parallel line will be -5/3.
