Arelli drank 2 3 liter of water Monday before going jogging. She drank 5 7 liter of water after her jog. How much water did Arel
bearhunter [10]

We have been that Arelli drank 2/3 liter of water Monday before going jogging. She drank 5/7 liter of water after her jog. We are asked to find the amount of water that Arelli drink altogether.

To find the amount of water that Arelli drink altogether, we will add amounts of water drank before going to jogging and after the jogging.

\text{Amount of water that Arelli drink altogether}=\frac{2}{3}+\frac{5}{7}

Let us make a common denominator.

\text{Amount of water that Arelli drink altogether}=\frac{2\cdot 7}{3\cdot 7}+\frac{5\cdot 3}{7\cdot 3}

\text{Amount of water that Arelli drink altogether}=\frac{14}{21}+\frac{15}{21}

Now we will combine numerators.

\text{Amount of water that Arelli drink altogether}=\frac{14+15}{21}

\text{Amount of water that Arelli drink altogether}=\frac{29}{21}

\text{Amount of water that Arelli drink altogether}=1\frac{8}{21}

Therefore, Arelli drank 1\frac{8}{21} liters of water altogether.

Write an equation for the line parallel to y= -7x+15 that contains p(9,-6)
NISA [10]
The slope of the line we seek must me the same as the slope of the given line because THE LINES ARE PARALLEL.

The two lines never meet.

The slope of the given line is -7.

See it?

Plug -7 and the given point into the point-slope formula.

y - (-6) = -7(x - 9)

Solve for y.

y + 6 = -7x + 63

y = -7x + 63 - 6

y = -7x + 57

A line has a slope of 1 and passes through the point (10, 13). What is its equation in slope-intercept form?
icang [17]

y-y1=m(x-x1)

y-13=1(x-10)

y-13=x-10

y=x-10+13

y=x+3

Hope this helps!
