Answer:

infinite solutions

Step-by-step explanation:

x+2y=10

6y=-3x+30

To solve for x  and y we use substitution method

LEts solve the first equation for x

x+2y=10

Subtract 2y on both sides

x=10-2y

Now plug in x in second equation

6y=-3x+30

6y=-3(10-2y)+30

6y=-30+6y+30

6y=6y

Both sides are same , so both x  and y have infinite solutions.

Harry had $32. He spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. If Harry had bou
sattari [20]

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.
