When they ask for combining the variable terms, you take one of the variable terms and move to the other side of the equation and change its sign. From there, you cross multiply those variable terms and simplify. Once you simplify, you look at the denominator and that will be your answer.
Similarly for the constant terms, you take one of the constant terms and move to the other side of the equation and change its sign. Again, you cross multiply these two constant terms and simplify. The denominator you get after simplification will be your answer.
Answer:

Step-by-step explanation:
Answer:
24ft
Step-by-step explanation: I could be wrong because I haven't done this for a while but if you add all of the numbers together you should get 24 if I am using the right equation.
X=15
Y=3
2(15)=30
3(3)=9
30+9=39
2x + 3y = 1470
3y = -2x + 1470
y = -2/3x + 490 <== slope intercept form
=================
y = -2/3x + 490
slope = -2/3
y int = (0,490)
=================
description of graphing : Plot ur point at (0,490). Since the slope is -2/3, starting at (0,490)...go down 2 and to the right 3,then down 2 and to the right 3 and you will eventually cross the x axis at the x intercept.
The x intercept can be found by subbing in 0 for y and solving for x
y = -2/3x + 490
0 = -2/3x + 490
2/3x = 490
x = 490 * 3/2
x = 1470/2 = 735...so ur x intercept is (735,0)
therefore, your line will cross the x axis at (735,0)
========================
function notation is : f(x) = -2/3x + 490
========================
suppose his profit is 1593....
2x + 3y = 1593
3y = -2x + 1593
y = -2/3x + 531
the graphs for the two months :
similarities : they both have the same slope of -2/3
differences : they have different x and y intercepts
By the way, these are parallel lines
===================
sorry about the last one....can't see the 3rd month graph
