Perimeter of rectangle = 2(14 + 3.5) = 35cm.

Area of rectangle = 14 * 3.5 = 49cm².

Find the equation of the line which passes through the point (−2,−5) and is parallel to the line −3x+5y=−4.
leonid [27]
-3x+5y=-4
5y=3x-4
Y=3/5x-4/5


When it parallel to the line y=3/5x-4/5

It can be y=-3/5x+b

-5=6/5+b

B=-5-6/5=-25/5-6/5=-31/5

Y=-3/5x-31/5

3/5x+y=-31/5

Multiply 5

3x+5y=-31

Y=5x-1<br>2x+y=13 how to solve​
ira [324]

Answer:

x = 2, y = 9 or (2,9)

Step-by-step explanation:

Hello!

The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1

We can plug in the first equation into the second like this:

2x + y = 13 (we know y so we can plug it in)

2x + (5x - 1) = 13

2x + 5x - 1 = 13

7x - 1 = 13

Now we add 1 to both sides

7x - 1 + 1 = 13 + 1

7x = 14

x = 2

Now we plug in x to find y:

y = 5x - 1

y = 5(2) - 1

y = 10 - 1

y = 9

Help its difrrent question thx so much
irakobra [83]

Answer:

75% off

Step-by-step explanation:

I would personally say use a calculator, but whatever your instructor says.

First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.

Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.

So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
