Answer:
15x+25 ; 70
Step-by-step explanation:
Given that,
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :
y = 15x+25
For 3 hours,
y = 15(3)+25
= 45 + 25
= 70
So, the required option is (c) " 15x+25 ; 70 ".

Step-by-step explanation:
When solving matrices, we need to get the inverse of the matrix
2 6
0 1 we need to get the inverse
The inverse is
.5 -3
0 1
This is what we have to multiply before the coefficient matrix of 2
-3
