Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.
__
In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
Answer:
35 minutes
Step-by-step explanation:
12 minutes to 7:00 would be 6:48

therefore there are 35 minutes from 6:48 to 7:23
Answer:
B
Step-by-step explanation:
g(x)=(4-4)²
g(x) =0
and f(x)=x²
f(x)=0²
