Find the equation of the line that is parallel to the line x + 5y = 10 and passes through the point (1, 3).

shusha [124]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange x + 5y = 10 into this form

Subtract x from both sides

5y = - x + 10 ( divide all terms by 5 )

y = - $\frac{1}{5}$ x +2 ← in slope- intercept form

with slope m = - $\frac{1}{5}$

• Parallel lines have equal slopes, hence

y = - $\frac{1}{5}$ x + c ← is the partial equation of the parallel line

To find c substitute (1, 3) into the partial equation

3 = - $\frac{1}{5}$ + c ⇒ c = $\frac{16}{5}$

y = - $\frac{1}{5}$ x + $\frac{16}{5}$ ← equation of parallel line

What is 7 7/9 divided by 4/7

e-lub [12.9K]

Answer:

4 44/49

Step-by-step explanation:

7 7/9 is 70/9

then u use 70/9 multiply by 7/4(I call it keep, change, flip method for division of fraction)

You keep the 1st fraction and because it is a mixed fraction, changing it to improper fraction is easier to solve it later on.

after that, you change the division sign to multiply sign(÷ to ×)

then you flip the 2nd fraction, which means 7/4 becomes 4/7

So overall it becomes 60/7 × 4/7 =240/49,4 44/49 as a mixed fraction.

Answer is 4 44/49
