Sum is 17 and their difference is 3

The numbers are 10 and 7

Step-by-step explanation:

I will assume you mean 2 numbers

x+y = 17

x-y =3

Add these two equations together

x+y = 17

x-y =3

2x = 20

Divide by 2 numbers

2x/2 = 20/2

x = 10

Now we need to find  y

x+y =17

10 +y =17

Subtract 10 from each side

10-10+y =17-10

y =7

The numbers are 10 and 7

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
