Answer:

15 & 23

Step-by-step explanation:

I used an insert and check kind of method. Basically you insert numbers and check if they work for both equations. the equations are as follow:

X + Y = 38

X - Y = 8

I inserted various combinations of numbers and we'll use one as reference.

I used 16 and 22. 16 and 22 correctly fits the requirements of the first equation but when we do 22 - 16 we see that it equals 6. this is 2 off from the second equation. Using this info I ask myself, was the answer close or far from the answer needed.

Hope this answered any questions. please comment on this if you need any othern have a nice day!

Answer:

Since the sum is 38, y must be 15. And indeed the difference between 23 and 15 is 8, so it's correct.

The median is a halfway point in the set of data.

List the numbers in order from smallest to largest:

111, 129, 144, 149, 152, 162, 166, 171

Because there are an even number of values in the data set, find the two middle numbers, add them together and then divide by 2:

Median = ( 149 + 152 ) /2

Median = 150.5

How could you use coordinate geometry to prove that segment BC is congruent to segment AD?
liberstina [14]

Answer:

  Prove the lengths are the same

Step-by-step explanation:

When we say segments are congruent, we mean their lengths are the same.

__

Let's see if they are congruent.

  AD = √((3-(-3))² +(2-2)²) = 6

  BC = √((6-0)² +(6-6)²) = 6

AD ≅ BC . . . . their lengths are the same
