<span>A system has two linear equations in two variables. The graphs of the equations have the same slope but different y-intercepts. How many solutions does the system have?

A. 0</span>
They have no solutions because these two lines are parallel. They have the same slope. However, two parallel lines have no solutions because they never intersect.
Hope this helps.
Answer:
The price per t-shirts is $8.5.
Step-by-step explanation:
Let us assume the price per t- shirt = $m
The cost of 75 t-shirts = $637.50
Now, the total cost for 75 t-shirts = 75 x ( cost of 1 t-shirt)
⇒ $637.50 = 75 x ( m)
⇒ m = $637.50 / 75
or, m = 8.5
Hence, the price per t-shirts is $8.5.
The expressions that are equivalent to 64^1 would be 4^3, 8^2, and 2^6! :)
