Answer:
x=3; y=3
Step-by-step explanation:
y = -1/2 x + 9/2
so if we multiply by 2 on both sides
2y = -x + 9
and we know that y = 3x-6
so we get
2(3x-6)=-x+9
6x-12 = - x + 9
7x = 21
x = 3
y = 3 * 3 - 6
y=3

x=3, y=3
You put them in the equation and they should work.

Answer:
a) 4 months
b) $600
Step-by-step explanation:
1. x - number of months the total amount paid to be the same for both stores.
2. That same amount for store A: 
3. That same amount for store B: 
4. Since it's the same amount for both stores we can make an equation:
5. To find that same amount, we can use either side of above equation:
Answer:
This is called a sample.
In statistics, we take a random 'sample' of people so that we can estimate values for the entire population!
So, say for example you want to find out what percent of students in your school are girls. You take a sample, like this again, of 30 students, and 3/10 are girls, then you can apply it to the rest of the population.
Hope this helps!
