The sum of two numbers is 56, and their difference is 10. What are the numbers? ОА.
33 and 23
OB.
30 and 26
OC.
20 and 36
OD
20 and 30

Let the two numbers be 'm' and 'n'

Now we can get,

1) m + n = 56

2) m - n = 10

m + n = 56

n = 56 - m

m - n = 10

By substituting n = 56 - m we get,

m - (56 - m) = 10

56 - m - m = 10

56 - 2m = 10

-2m = 10 - 56

-2m = -46

m = - 46/-2

Now, we will find 'n' by the equation 1 ,

n = 56 - m

n = 56 - 23

33 + 23 = 56

33 - 23 = 10

Hence, verified

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
