Solve the system of equations by using substitution.
x+8y=-2
x-3y=20

(14, -2)

Step-by-step explanation:

To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:

Now we know what x equals. Let's substitute this into the second equation:

We can then simplify:

Given equation

Combine y terms

Add 2

Divide by -11

So, we now know the value of y = -2.

To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:

Substitute for y

Distribute 8

Add 16

So, we now know the value of x = 14.

Therefore, we know a solution to the system of equations is (14, -2).

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
