Identify the solution of the system -2x-4y=1<br> 12y=-6x-3
RoseWind [281]
-2x - 4y = 1
<u>12y</u> = <u>-6x - 3</u>
 12         12
   y = -0.5x - 0.25

-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
<u>     - 1  - 1</u> 
       <u>0x</u> = <u>0</u>
        0     0
         x = 0
-2(0) - 4y = 1
0 - 4y = 1
<u>-4y</u> = <u>1</u>
 -4    -4
   y = -0.25
(x, y) = (0,-0.25)

Solve for z. –z + 4= -4
slega [8]

Answer:

-z+4=-4

Step-by-step explanation:

First, you want to move the positive four to the other side to isolate the variable.

-z=-8

You cannot have a negative variable, so divide both sides by 1.

-z/1=-8/1

Your answer would be:

Z=8

Hope this helps!!

Julie and Kristen are the partners in a local sporting goods shop. They needed $51,000 to start the business. They invested in t
exis [7]
5:12 means there are 17 parts
Percentages are calculated by dividing the part by the total, and multiplying by 100
Julie put in 5 out of 17 parts so:
\frac{5}{17}×100=29.4%
Kristen owns the rest of the business \frac{12}{17}×100=70.6%

The amount of money doesn't make a difference, as the percentage will always be the same.
