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:
-2
Step-by-step explanation:
The equation of a line in slope intercept form is
y = mx +b where m is the slope and b is the y intercept
y = -2x+4
The slope is -2 and the y intercept is 4

Answer:
The correct answer is 288.
Step-by-step explanation:
A person has to order a new car.
He has a choice of 9 colors.
Other parameters include air conditioning, heated seats, anti-lock brakes, power windows, CD player.
Each of these parameters he have two options each.
Therefore the number of different ways can a new car be ordered in terms of these options is given by 9× 2 × 2 × 2 × 2 × 2 = 288.
The person have 288 ways of choosing which kind of car is he going to order for himself.
