The points (30, 50). (-10, 30) and (-20, s) all lie on the same line. What is the value of s? Show your work.

s = 25

Step-by-step explanation:

First we go from point (30, 50) to point (-10, 30).

Change in x: -10 - 30 = -40

Change in y: 30 - 50 = -20

Since a change in x of -40 results in a change in y of -20, we divide both changes by 4 to get:

a change of -10 in x results in a change of -5 in y.

Now we go from point (-10, 30) to point (-20, s).

The change in x is -20 - (-10) = -10

The corresponding chang ein y must be -5.

y = 30 - 5 = 25

s = 25

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
