Answer:
x=8
Step-by-step explanation:
Because you are solving for x, you want to cancel out the y terms. You can do this by multiplying the entire equations by numbers that will make the y terms have equal numbers but opposite signs.
2(2x-5y=1)
5(-3x+2y=-18)
This turns into
4x-10y=2
-15x+10y=-90
The y terms cancel out, and the other terms can be added together.
-11x=-88
x=8

Solution -
A student who was skeptical about this value decided to conduct a survey by randomly sampling 36 students. On average, the sampled students slept 6.6 hours per night.
The sample mean is the average of the 36 sampled students, which is 6.6 hours. So 6.6 represents the <u><em>sample mean.</em></u>
College newspaper stated that college students get an average of 7 hrs of sleep each night.
The claimed population mean is the stated average from the newspaper article, which is 7 hrs. So 7 represents the <u><em>claimed population mean.</em></u>
Answer: 8 because 24 words divided by 4 weeks is 8.
Answer: y = -x - 3
Using the parent function/formula y = mx +b, you can use the slope formula 
to determine that the slope is negative. Then, using the answer to the slope equation (m), you can use 2 points from the table to solve the equation for b. Then just write the equation using y, x, value of m, and value of b.
