the system has no solution.
Option C is correct.
Step-by-step explanation:
We need to solve the system of equations by substitution
Putting value of x from eq(2) into eq(1)
As as 0≠4is not true, we cannot find the value of y so the system has no solution.
Option C is correct.

Y determines how many hours, and x gives you the whole amount.
1 cup of blueberries = 1 loaf, so 2 cups of blueberries = 2 loaves. The answer is 2
Times the bottom equation by -4 to cancel out the x’s.
Add the equations.
Solve for y.
Plug in y to find x.
a.
In order to find the common ratio, we just need to divide a term by the term that comes before it.
So using the terms 20 and -5, we have:
b.
The recursive rule can be found with the formula:
Where an is the nth term and q is the ratio. So we have:
c.
The explicit rule can be written as:
Where an is the nth term, a1 is the first term and q is the ratio. So:
