15 = rate * 40
rate = 15/40
rate = 0.375 * 100% = 37.5%

Answer:
0 solutions / no solutions
Step-by-step explanation:
If two lines have the same slope but different y-intercepts, it means that they are parallel.
For example, we have two lines:
y = x
y = x + 1
Both lines have the same slope of 1, but different y - intercepts. Because each equation increases the x and y at the same right (slope) but started at different points, the two equations will never touch.
It's similar to two runner who run at the same pace. If one runner started 50 meters ahead, that runner will always be ahead 50 meters (y-intercept) because they both run at the same rate.
Answer:
Solving for 
we got 
and replacing this we got:
And then the best option for this case would be:
b.csc x
Step-by-step explanation:
For this case we have the following expression given:
We know from math properties that the definition for cot is
If we use this definition we got:
Now we can use the following identity:
Solving for we got and replacing this we got:
And then the best option for this case would be:
b.csc x
