Hello!

You can solve this algebraically

-15 = 22x + 7

Subtract 7 from both sides

-22 = 22x

Divide both sides by 22

-1 = x

The answer is A) x = -1

Hope this helps!

The sum of 2 numbers is 25. Their difference is 7. Find the numbers. Let x=1st number and y=2nd number
Alex Ar [27]

Answer:

x= 16 and y = 9

Step-by-step explanation:

1 st equation ; x+y = 25

2 nd equation ; x- y = 7

from 1 st equation

x = 25 - y

now putting value of x in 2 nd equation

x- y = 7

25 - y-y = 7

25 -2y =7

25-7 = 2y

18 = 2y

18/2 = y

y = 9

again

putting value of y in 1 st equation

x = 25-y

x = 25-9

x= 16

20x = -157

x = -157/20

x = -7 - 17/20

Which linear function represents the line given by the point-slope equation y-8=
Nina [5.8K]

Answer:

f(x)=x+4

Step-by-step explanation:

we have

y-8=(x-4)

This is the equation of the line in point slope form

where

The slope is m=1

The point is (4,8)

Convert to slope intercept form

Isolate the variable y

Adds 8 both sides

y-8+8=x-4+8

Combine like terms

y=x+4

Convert to function notation

f(x)=x+4
