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
