Another way to do it is
2x-y=17
x-y=10, x=10+y
substitute x=10+y for x in 2x-y=17 and get
2(10+y)-y=17
20+2y-y=17
20+y=17
subtract 20 from both sides
y=-3
subsitute y=-3 into equation x-y=10
x-(-3)=10
x+3=10
subtract 3 from both sides
x=7
or subsitute into 2x-y=17
2x-(-3)=17
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by two
x=7
A statistical question can be used to illustrate a population or a sample
All the TV screens in the state of Oregon represents the population
<h3>How to determine the population</h3>
The statistical question is given as:
"What is the average cost of a 48 inch screen TV in the state of Oregon?"
From the above question, we have the following parameters:
- All TV screens
- 48 inch screen TV
All the TV screens in the state of Oregon represents the population of the distribution, while the 48-inch screen TV represents the sample

No. Since you can only draw from the corners to get triangles, you will end up with two right triangles because of the corners. If it is a right triangle, it can obviously not be obtuse.
