Answer:
The slope is 5/2 and the y intercept is -1
Step-by-step explanation:
To find the slope and the y intercept, we will write the equation in slope intercept form, y =mx+b where m is the slope and b is the y intercept
5x -2y =2
Add 2y to each side
5x-2y+2y =2 +2y
5x = 2+2y
Subtract 2 from each side
5x-2 = 2y+2-2
5x-2 =2y
Divide each side by 2
5x/2 -2/2 = 2y/2
5/2x -1 = y
y = 5/2x -1
The slope is 5/2 and the y intercept is -1
Answer: here's the answers to the problems
6) 17
8) 2.5
X is -8
To solve the problem you have to get X by itself. So you would multiply every number in the equation by 4. Which will give you -X + 12 = 20
Now you have to subtract 12 on both sides of the equal side giving you -X = 8 since the positive twelve cancels out.
Finally you divide by negative 1 since X can NOT be a negative!
Your final answer should be X = -8
I hope that helped and you know what to do now...
Answer:
171
Step-by-step explanation:
Step 1: Let "x" and "y" be the variables
Let x = the number of adult tickets sold
Let y = the number of child tickets sold
Step 2: Add the variables and subtract the "x" variable
x + y = 486 y = 486 - x
Step 3: Add the given amounts by the variables next to it to equal the total
5.50x + 4y = 2416.50
5.50x + 4(486 - x) = 2416.50
5.50x + 1944 - 4x = 2416.50
Step 4: Subtracting the result from the number of tickets the booth sold
1.5x = 472.5
x = 315
y = 486 - 315 = 171
Therefore, there are 171 tickets of each type sold.
This is not solvable there is no given total in my opinion
