Number 7 please! I need help badly
melamori03 [73]

Answer:

A computer costs $225 and a printer $150.

Step-by-step explanation:

Let c be the cost of a computer and p the cost of a printer, then:

3c + p   = 825

4c + 2p = 1200

Multiply the first equation by -2:

-6c - 2p = -1650

Add this to the second equation:

-2c = -450

c = 225.

Now substitute  c = 225 in the first equation:

3*225 + p = 825

p = 825 - 675 =  150.

Determine if the following system of equations has no solutions, infinitely many
DochEvi [55]

Answer:

There is one solution

Step-by-step explanation:

2x + y = -1

8x + 3y = -2

Multiply the first equation by -4

-8x -4y = 4

Then add the equations together to eliminate x

-8x -4y = 4

8x + 3y = -2

--------------------

   -y = 2

Multiply by -1

y =-2

Now find x

2x+y =-1

2x+-2 =-1

Add 2 to each side

2x-2+2=-1+2

2x=1

Divide by 2

x = 1/2
