The equation and steps are...

First, find the slope of the original equation.  In this case, the slope is -8.  You know that perpendicular lines have slopes that are negative reciprocals, so the negative reciprocal of -8 is 1/8.


Now, use this new slope and the given point to find the y-intercept:

 y = mx + b

4 = (?)(2) + b

4 = ? + b

15/4 = b

 

Use the new slope and y-intercept to write the new linear equation:

 Answer:

y = 1/8x + 15/4


Sorry if i'm wrong

Kyle gave 2/7 of his money to his wife and spent 3/5 of the remainder. If he had $300 left, how much money did he have at first?
weqwewe [10]

<u>Answer: </u>

Kyle gave 2/7th  of his money to his wife and spent 3/5 of the remainder. If he had $300 left, the money had by Kyle at first is $1050

<u>Solution: </u>

Step 1:

Consider “x” as the money which Kyle had initially.  

From question, Kyle gave 2/7th of his money to his wife. So the remaining money left with Kyle is given as,

= 1 - \frac{2}{7}

= \frac{7 - 2}{7} = \frac{5}{7} ----- eqn 1

Now the remaining money left with Kyle is 5/7th.Given that Kyle spent 3/5 of the remaining money.  

Now the remaining money left with Kyle is given as  

= 1 - \frac{3}{5} = \frac{5 - 3}{5} = \frac{2}{5}

Now kyle is left with $300, which is 2/5th of the initial money x .

We get equation as  

\frac{2}{5} x=300

2x = 1500

x = 750

Now Kyle is left with 750$ which is 5/7th of the initial amount x.( by using eqn 1)

We get equation as

\frac{5}{7} x = 750

5x = 5250

x = 1050

So the amount had by Kyle at first is $1050
