It can give you a pretty good idea of how many degrees everything is. for example if something was 13degrees, you would be able to make an estimate because you know how much one degree is.
Answer:
(3,4)
Step-by-step explanation:
first you're going to solve the equation -2x
your equation should now be: 
next you're going to substitute the given value of -2x into the equation 
so your equation should now be: 
next you're going to solve the equation for y
equation should now be: y=4
than you're going to substitute the given value of y into the equation
×
then you're going to solve the equation for x
your equation should now be: x=3
then the possible solution of the system is the order pair: (x,y)=(3,4)
H=-9/2
Divide both sides of the equation by -36
Any expression divided by itself equals 1
Answer: x= 8 x= -4
