How many solutions are there to the system of equations? StartLayout enlarged left-brace 1st row 4 x minus 5 y = 5 2nd row negat
kkurt [141]

Answer:

Only one solution  x=\frac{5}{4},y=0

Step-by-step explanation:

4x-5y=5..............(1)\\0.08x+0.10y=0.10...........(2)

Multiply equation (2) by 50

4x-5y=5........(3)

Now from equation (1)+ equation(3)

8x=10\\x=\frac{10}{8}\\x=\frac{5}{4}

Put the value in equation (1)

5-5y=5\\5y=0\\y=0

hence only one solution exists\left(\frac{5}{4},0\right).

The regular price of a computer is $1200 and the regular price of a printer is $300. The regular price of a computer is 1200 dol
Oksanka [162]

Answer:

$1380

Step-by-step explanation:

  • The regular price of a computer is $1200
  • The regular price of a printer is $300.

The electronics store offers a 40% discount on the printer only when the computer is purchased at the regular price.

Discount on the Printer = 40% of $300 =0.4 X 300 =120

Promotional Price of the Printer = $300-120 =$180

Therefore, the total cost of the computer and the printer at the promotional price

=Regular price of a computer + Promotional Price of the Printer

=1200+180

=$1380
