Answer:

x= 12  y= -3

Step-by-step explanation:

Rearrange.

x+y=9

x-y=15

Get x by itself, cancel out the y's and you'll get this:

2x=24

x= 12

Plug it in.

12+y=9

Get y.

y= -3

Check your work. I hope this helped.

Solve the formula F=9/5C+32 for degrees<br> Celcuis C. show all your steps
borishaifa [10]

Start with your given equation - F=9/5C+32

Subtract 32 from both sides - F-32=(9/5) degrees C

Multiply both sides by 5 - 5(F-32)=9C

Divide both sides by 9 to isolate C - (5/9)(F-32)=C

Answer - C=(5/9)(F-32)

Need help ASAP
Tresset [83]

Answer:

upper left

Step-by-step explanation:

The generic equation for a circle centered at (h, k) with radius r is ...

(x -h)^2 +(y -k)^2 = r^2

Comparing that equation to the one you have, you can see that ...

-h = 0

-k = +3

r^2 = 9

Then you have (h, k) = (0, -3) and a radius of 3.

The circle has its center on the y-axis 3 units below the x-axis and just touches the x-axis. This is a description of the graph at upper left.
