To graph a line, first, we need to plot out values. Let’s find a few: if y is 2, -x would be 2-6, and x would be 4. If y is -2, x would be 8.
Now, all you have to do is put a few more of those points on a line graph and connect them.
Good luck!

Step 3 :
10y3 - 5y2 - 10x + 4
Simplify ————————————————————
2y - 1
Checking for a perfect cube :
3.1 10y3 - 5y2 - 10x + 4 is not a perfect cube
Final result :
10y3 - 5y2 - 10x + 4

2y - 1
System of Equations
For the problem to solve we'll use the following variables:
x = number of the early bird tickets sold
y = number of the regular tickets sold
Haley sold a total of 20 tickets, thus:
x + y = 20 [1]
Early bird tickets cost $10 and regular tickets cost $15, thus the total money collected is:
10x + 15y = 225
Dividing by 5:
2x + 3y = 45 [2]
We have to solve the system of equations [1] and [2].
Multiply [1] by -2:
-2x - 2y = -40 [3]
Add [3] to [2]:
-2x - 2y +2x + 3y = -40 + 45
Simplifying:
y = 5
Substituting in [1]:
x + 5 = 20
Subtracting 5:
x = 20 - 5
x = 15
Solution: Hayley sold 15 early bird tickets and 5 regular-priced tickets
The order pair solution is (15,5)
Answer:
Step-by-step explanation:
m+2/2 = 1/2
m=0.5
so
2m+4=5 is the correct answer
