Answer:

After 15 days they'll both have $10

Explanation:

100 (Xavier's total)- 6x (6 dollars every day) = 160 (Zach's total amount) -10x (10 dollars every day)

100-6x=160-10x\\

+10x on both sides

100+4x=160

-100 on both sides

4x=60

/4 on both sides

x=15

Answer choices:<br><br> y = x<br> y = 1/4x - 2<br> y = -x + 7/4<br> y = 7/4x - 2
kumpel [21]

Answer:

all in all it's y=x

Step-by-step explanation:

A (4,1); B (0,-2)

G=delta y

--------

delta x

1-(-2)

-------

4-0

3/4=G

3/4=y-1/x-4

4 (y-1)=3 (x-4)

4y-4=3x-12

4y=3x+4-12

y=3/4x-3

Find an equation of the line parallel to x=5y-9 and passing through (2,-4). Express in standard form.
Anon25 [30]

Answer:

x - 5y = 22

Step-by-step explanation:

Step 1:  rewrite the equation of the given line in to slope-intercept form by solving for y

 x = 5y - 9    

     -5y = -x - 9               (subtract 5y and x from both sides)

        y = x/5 + 9/5           (divide both side by -5)

Step 2:  Our line is parallel to this line, so it has the same slope, but a different  y-intercept, so set up the equation...

  y = x/5 + b      

We are given a  point (x, y) of (2, -4), so plug that in and solve for b.  

 -4 = 2/5 + b

            -4 - 2/5 = b      (subtract 2/5 from both sides to isolate b)  

                   -20/5 - 2/5 = b

 

                         -22/5 = b      (simplify)

So the equation of our line is  y = x/5 - 22/5

Step 3:  Standard form is ax + by = c, where a is a positive integer

subtract x/5 from both sides...

-x/5 + y = - 22/5

multiply by -5 so x becomes a positive integer

x - 5y = 22
