4x – 2y = -8
y = 2x + 4
Answers
Answer:
Set any x and then compute y as 2x + 4. The pair solves the equations.
Step-by-step explanation:
4x - 2y = -8
4x = 2y - 8
2x = y - 4
y = 2x + 4
2x + 4 = y
2x = y - 4
Both equations are the same, so any pair of x and y for which 2x = y - 4 works.
Set any y and then compute x as (y - 4)/2
Alternatively
2x = y - 4
2x + 4 = y
Set any x and then compute y as 2x + 4.

What is an equation of the line that passes through the point (-6,-2)(−6,−2) and is parallel to the line 3x-2y=23x−2y=2
Answers
Answer:
y = 3/2x + 7
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is 3x - 2y = 2. First, let's put this into standard form.
3x - 2y = 2
Add 2y to both sides to make y positive.
3x = 2y + 2
Subtract 2 from both sides to isolate y.
3x - 2 = 2y
Isolate y further by dividing both sides by 2.
3/2x - 1 = y or y = 3/2x - 1
This is now your first line. Its slope is 3/2. A line parallel to this one will also have a slope of 3/2.
Plug this value (3/2) into your standard point-slope equation of y = mx + b.
y = 3/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-6, -2). Plug in the x and y values into the x and y of the standard equation.
-2 = 3/2(-6) + b
To find b, multiply the slope and the input of x (-6)
-2 = -9 + b
Now, add 9 to both sides to isolate b.
7 = b
Plug this into your standard equation.
y = 3/2x + 7
This equation is parallel to your given equation (y = 3/2x - 1) and contains point (-6, -2)
Hope this helps!
What is the result when we simplify the expression ( 1 + 1 /x ) ( 1 − 2/x + 1 ) ( 1 + 2/ x − 1 ) ?
Answers
Step-by-step explanation:
Let y be 1/x. Then 2y = 2/x.
We wish to simplify (1 + y)(2 - 2y)(2y).
(1 + y)(2 - 2y)(2y)
= 4y(1 + y)(1 - y)
= 4y(1 - y²)
= 4y - y³
= 4/x - 1/x³.
P.S. Writing it as (4x² - 1)/x³ is fine.

A carnival is selling red tickets for rides and yellow tickets for games. The red tickets are $1.25 each and the yellow tickets are $0.75 each. The total number of tickets sold was 1,032 and the total sales was $979. Let r represent the number of red tickets sold and y represent the number of yellow tickets sold. Which pair of linear equations can be used to find the number of red tickets sold?
{ r + y = 979 0.75 r + 1.25 y = 1,032
{ r + y = 1,032 0.75 r + 1.25 y = 979
{ r + y = 979 1.25 r + 0.75 y = 1,032
{ r + y = 1,032 1.25 r + 0.75 y = 979
