Answer:
Only option C shows a function
Step-by-step explanation:
The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. This means that a vertical line made in the domain of the function can crosses the curve of the function only once. If it crosses the curve of the function more than once, then the curve is not a function.
In option A, a vertical line would cross two values, so it is not a function.
The curve of option B is a vertical line itself, so a vertical line would intersect an infinite amount of points; then it is not a function.
Option C is a function because a vertical line would only intersect the function's curve (which is a line) once.
Answer: his weekly allowance is $8
The model to solve the problem is
X/2+8=12
Step-by-step explanation:
To get Eduardo's weekly allowance
Say it is x
Now he spent half of x on clothes and earns extra $8 more to end up with $12
Therefore
x/2+8=12
x/2=12-8
x/2=4
x=8

Answer:
Option B, 1/4 (x - 5) = 13
Step-by-step explanation:
An inequality has a less than, greater than, less than or equal to, and greater than or equal to. <u>But, there are no equal signs allowed in a inequality. That makes it an expression.</u>
Answer: Option B, 1/4 (x - 5) = 13
