Answer:

$125,000.12 last year

$375,000.36 this year

Step-by-step explanation:

Last year, her profits were x.

This year, the profits are three times greater, so they are 3x.

Altogether for both years, the profits are x + 3x = 4x.

The profits for both years combined are $500,000.48

4x = 500,000.48

Divide both sides by 4.

x = 500,000.48/4

x = 125,000.12

The profits last year were $125,000.12

This year, the profits were 3x = 3(125,000.12) = 375,000.36, or $375,000.36

Find the slope intercept form of the line whose slope is 2 and passes through the point (-7,10)
disa [49]

Answer:

y=2x+24

Step-by-step explanation:

Hi there!

We are given that a line has a slope of 2 and passes through (-7, 10)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the y-intercept

As we are already given the slope, we can immediately substitute it in for m

So replace m with 2 in y=mx+b

y=2x + b

Now we need to find b

As the equation passes through the point (-7, 10), we can use its values to help us find the value of b

Substitute -7 as x and 10 as y

10 = 2(-7) + b

Multiply

10 = -14 + b

Add 14 to both sides

24 = b

Substitute 24 as b into the equation

y = 2x + 24

Hope this helps!

What is the equation of the line that has a y-intercept of 5 and is parallel to
victus00 [196]

Answer:

A) 2x + 5

Step-by-step explanation:

First, turn 2x - y = 16 into 2x - 16 = y by adding the <em>y</em> on both sides and subtracting 16 from both sides.

You'll see that option A is the only option that matches the original function that we're comparing to.

Graphs will always be parallel to each other if they have the same slope, and both these functions have the same slope of 2.
