The sum of two numbers is - 10. If one number is subtracted from the other, their difference is - 8. Find the numbers.
Lera25 [3.4K]

Answer:

the sume of two numbers is 2. if one number is subtracted from the other, their difference is 8. find the numbers---->

Step-by-step explanation:

X+Y=2

X-Y=8

If you subtract X+Y with X-Y, you get 2y, and so that equals 2-8, that is -6.

2y=-6

y=(-6)/2

y=-3

-3+X=2

x=2+3

x=5 and y=-8

Check

-3+5=2

5-(-3)=8

Write the equation of the line that passes through the points<br> Y=2x+5
sattari [20]

Answer:

Parallel means that the lines never intersect. If the equation of the new line is y=ax+b , then the system

y=ax+b

y=2x+5

needs to have no solutions. Subtracting the equations gives us

(a−2)x+(b−5)=0

In order for this to ever be 0 we need either a≠2 or b=5 , so to stop this from happening, we will require both a=2 and b≠5 .

Since our line now has the form y=2x+b , and (4,5) is on the line, then the equation

5=2⋅4+b

should be true. Since this implies that b=−3 , we have that the parallel line going through (4,5) has equation

y=2x−3

What is an equation of a line that goes through point (4,-5) and is parallel to y=2x+8?

Which line is parallel to the line y = 2x -4?

What is an equation for a line parallel to y = 5 x -5 and passing through the point (4,19)?

What is an equation for the line that is parallel to y= -4x

ZABC and ZORS are supplementary angles
Sonja [21]

m<QRS = 80 degrees.

Supplementary angles = a total of 180 degrees. So if angle ABC = 100, angle QRS would = 80 degrees.

Please mark as brainliest :D
