Write an equation for the line parallel to the line 5/8x−7/6y =2 through the point (7,−1).

LiRa [457]

$y = - \frac{28}{48x - 15} - \frac{125}{321}$ is the answer.

Step-by-step explanation:

For this question,

• First, find the slope of the line parallel to the line 5/8x−7/6y=2 :-

$m = - \frac{28}{ - 15 + 48x}$

•Second, find the equation of the line,

$y = - \frac{28}{48x - 15} - \frac{125}{321}$

-1 3/5 divided by (-2/3) write as mixed number

hichkok12 [17]

Step-by-step explanation:

$- 1 \frac{3}{5} \div \frac{ - 2}{3}$

Convert the mixed numbers above to improper fractions. Thus:

$\frac{ - 8}{5} \div \frac{ - 2}{3}$

In order to simplify the fractions above, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that -2/3 to -3/2. Hence,

$\frac{ - 8}{5} \times \frac{ - 3}{2}$

$\frac{ - 8 \times - 3}{5 \times 2}$

$= \frac{24}{10}$

$= 2 \frac{4}{10}$

$= 2 \frac{2}{5}$

Line j is parallel to line k. Find the m

Rufina [12.5K]

Answer:

- 8.14 = m = slope

Step-by-step explanation:

We know from the diagram that 8x-7 + 5x+18 = 180 so x = 13

so 8x -7 = 97

slope = tan 97 = -8.14
