Solve the system 2x+4y=16 5x +3y=19 then find the value of y/x
AURORKA [14]

Answer:

I would change 2x+4y=24 into x=12–2y

To do that, divide both sides by 2 and then subtract 2y on each side.

After that, substitute for x. 3x+2y=19 would become 3(12–2y)+2y=19.

Then solve.

3(12–2y)+2y=19

36–6y+2y=19

-4y+36=19

-4y=-17

y=4.25

Then, substitute y in either equation.

Either this:

3x+2y=19

3x+2(4.25)=19

3x+8.5=19

3x=10.5

x=3.5

Or:

2x+4y=24

2x+4(4.25)=24

2x+17=24

2x=7

x=3.5

Or you could solve it in the equation you created in the beginning:

x=12–2y

x=12–2(4.25)

x=12–8.5

x=3.5

The coordinates where the lines intercept are (3.5, 4.25).

Sorry for the long answer!

I need help drawing the graph of -2x+2y=-4
True [87]
Arrange in slope intercept form.....
2y = 2x -4
y = x - 2

So, the line would go up......crossing the y axis at -2.........hope this helps

The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greate
zhannawk [14.2K]

Answer:

35

Step-by-step explanation:

35 is exactly 152 but since its asking for greater then you're right it is 36.

But since it says '>' it means not equal to so it would be:

x > 35

or

x ≥ 36

Sandra uses her office fax machine to send fax at the rate of $0.10 per page. She decides to rent a fax machine for $80 a year.
Maksim231197 [3]
Part A: 
 First we define the variable to be used for the problem:
 x: the number of pages that Sandra should fax
 The inequality for rent is:
 0.06x <= 80
 Note that the price will be less than using the fax from the office, since for the same number of pages, we have:
 y = 0.10x
 Answer:
 
an inequality that can be used to calculate the number of pages that Sandra should fax in a year is:
 
0.06x <= 80

 Part B:
 0.06x <= 80
 From here we clear x:
 x <= 80 / 0.06
 x <= 1333.33333
 Nearest whole number
 x <= 1333
 Sandra can use the leased fax for 1333 pages and the cost will be:
 1333 * 0.06 = 79.98 $
 Using the office fax the cost will be:
 1333 * 0.1 = 133.3 $
  Answer:
 
By renting the sara machine, you save:
 
133.3-79.98 = 53.32 $
