I don't understand what you want solved for here...could you please tell me?
Answer:
Step-by-step explanation:
Discrete variables are those that can take only a finite number of values. This is not so for speed of an airplane. as it changes from time to time
This is hard to write... I hope this makes sense to you...
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero.
To do this, we will multiply -3 to (x=3y=31)
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73
Answer:
linear
Step-by-step explanation:
Step-by-step explanation:
40=6x+12
we know the total of everything is 40, so out that on one side.
1. Let the number be X
Therefore, six times the sum=6x
and twelve
so, 6x+12
put that together,
6x+12=40
