Write an equation of a line parallel to y = 5x + 4 that passes through (-1, 2)

s344n2d4d5 [400]

Answer:

$y=5x+7$

Step-by-step explanation:

step 1

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are equal

The equation of the given line is $y=5x+4$

The slope of the given line is $m=5$

The slope of the line parallel to the given line is also $m=5$

step 2

Find the equation of the line parallel to the given line

The equation of the line in point slope form is

$y-y1=m(x-x1)$

we have

$m=5$

$point\ (-1,2)$

substitute

$y-2=5(x+1)$

step 3

Convert to slope intercept form

Isolate the variable y

$y-2=5x+5$

$y=5x+5+2$

$y=5x+7$

At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls

ioda

Answer:

$Day\ 3 = 1\frac{3}{12}$

Step-by-step explanation:

Given

$Total = 2ft$

$Day\ 1 = \frac{1}{6}$

$Day\ 2 = \frac{7}{12}$

Required

Determine the amount of snow on day 3

This can be calculated using:

$Day\ 1 + Day\ 2 + Day\ 3 = Total$

Substitute values for the known parameters

$\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2$

Collect Like Terms

$Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}$

Take LCM

$Day\ 3 = \frac{24 - 2 - 7}{12}$

$Day\ 3 = \frac{15}{12}$

Express as mixed number

$Day\ 3 = 1\frac{3}{12}$

A family spends 20% of its monthly income on fuel. If they spend $324 a month on fuel, which is their monthly income?

nasty-shy [4]

Your answer is $1620.

To solve this, first look at what we're given. $324 is spent a month on fuel, and fuel is 20% of their income. Therefore, $324 is 20% of the family's income per month.

Now, to solve this, we're looking for 100% of the family's income. 20% is 1/5 of 100%, so therefore $324 is 1/5 of the family's full income.

To get 100%, then multiply 20% by 5 to get 100%, and therefore multiply $324 by 5 to get the full income.

$324 * 5 = 1620, or your answer.

Good luck!
