Input is domain and output is co-domain.
An expression is said to be a function if for every input, there is only one output. In table B, for every input, you get different outputs. Therefore, table B is a function.

Bobby wants to go on a school trip that will cost him $250. He comes up with an equation that represents how much he needs to sa
monitta
Yes, Bobby will have enough money if he saves for 9 weeks. You can find this through either substituting w for 9 in the equation, or solving the equation itself. 

Substituting:

25(9)+30
Substitute w for 9. 

225+30
Simplify. 

225+30=255
Solve. 

255 is greater than 250, so yes, he will have enough money saved. 


Solving the equation:

25w+30=250
Original Equation

25w=220
Subtract 30 from both sides. 

w=8.8
Divide both sides by 25. 

The number of weeks he needs is 8.8. When rounding it up, you get 9.

Solve the following system of equations. What is the x-value of the solution?
Leni [432]

Answer:

x = 1

Step-by-step explanation:

<u>Step 1:  Choose one of the equations to solve for y:</u>

x - y + 1 = 0

(-y) / -1 = (-1 - x) / -1

y = 1 + x

<u>Step 2:  Plug in y into either equation</u>

3x + 2(1 + x) = 7

3x + 2 + 2x - 2= 7 - 2

5x / 5 = 5 / 5

x = 1

Answer:  x = 1
