Answer:
y = -x +3
Step-by-step explanation:
The point-slope form can be a useful place to start.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
You require the line ...
y -(-4) = -1(x -7)
y = -x +7 -4 . . . . . . . . eliminate parentheses, add -4
y = -x +3 . . . . . . . . . slope-intercept form
Your answer should be 148! (Keep in mind that slope = change in y/ change in x.) Hope I helped!
Answer: 312 students purchased a ticket
Step-by-step explanation:
Let x represent the number of raffle tickets sold to parents.
Let y represent the number of raffle tickets sold to students.
The school sold 371 tickets. This means that
x + y = 371
x = 371 - y
The parent tickets cost $6 each and the student tickets cost $1.50 each and the school raised a total of $822. This means that
6x + 1.5y = 822 - - - - - - - -1
Substituting x = 371 - y into equation 1, it becomes
6(371 - y) + 1.5y = 822
2226 - 6y + 1.5y = 822
- 6y + 1.5y = 822 - 2226
- 4.5y = - 1404
y = -1404/-4.5
y = 312
x = 371 - y
x = 371 - 312
x = 59
Your answer is -1/2

Answer:
I don’t know about the last part but what I do know id the answer to the equation.
Answer: 1 1/3
Step-by-step explanation:
1. Remove the paranthesis
Removing the paranthesis will make it much easier to solve the equation.
We now have 4 1/6 + -2 5/6.
2. Rearrange the equation
We can’t have two symbols next to each other. We need to cross out one symbol so we can have only one. + and - = -. So let’s keep the "-" symbol.
We now have 4 1/6 - 2 5/6.
3. Solve the remaining equation
Now that we have a proper equation which we can solve, let’s do it.
We should then end up with 1 1/3.
Answer: 1 1/3
