Answer:
x=18
QR=29
RS=29
QS=29
Step-by-step explanation: 2X-7=5x-61=x+11 solve for x since all sides are equal
Lets say that the first number is x and the second number is y.
from the question we know that:
y=-3x and x+y=-4
from there, you need to replace the y in the second equation with -3x since we know that is what y equals so we can have an equation with only one variable.
x+-3x+-4
Then you solve for x.
-2x=-4
x=2
then you find y with the fact that y=-3x
y=-6
0.735 expressed as a fraction is 3/8

The function is a constant. No matter the input the output will always be equal to 9.
Hope this helps.

The domain is the input or x value in the coordinate and the range is the output or y value of the coordinate.
