Which table represents a function?

Mathematics
1 answer:
aleksley [76]3 years ago
8 0

Answer:

The first table. (By that, I am referring to the table directly under the question)

Step-by-step explanation:

A function has only one y value for every x value. Thus, for example the coordinates (-5, -5) and (-5, 5) could not be a function.

Ratling [72]

Let

x--------> the number of sessions

y-------> the total payment

we know that

without membership:

y=6x --------> equation 1


with membership:

y=100+4x --------> equation 2

using a graph tool------> resolve the system of equations

see the attached figure

the solution is the point (50,300)

that means

For x=50\ sessions

the cost is \$300 in both forms

so

to justify buying the membership

x > 50\ sessions

therefore

<u>the answer is</u>

x > 50\ sessions

Somebody please explain this I have a major exam soon and I really need to know how to solve problems like this​
nevsk [136]

Answer:

y = 2x - 3

Step-by-step explanation:

Step 1: Find the slope. You find the slope by using the formula y2-y1/x2-x1. (2, 1) and (4, 5) are our points. Let's find our values.

y2= 5

y1= 1

x2 = 4

x1 = 2

Plug in the numbers into the equation. 5 - 1 is 4. 4 - 2 is 2. 4/2 is 2. There. Our slope is 2.

Step 2: Find the b value. Keep in mind that an equation in point-slope form is y = mx + b, where m = the slope, and b = the y-intercept. For this part, you will plug in one of the points as x and y to find the b value. let's use point (4, 5)

The equation then becomes 5 = 2(4) + b. As we know, 2 * 4 is 8. Subtract 8 on both sides of the equation to cancel out the right side and isolate the b variable. 5 - 8 is -3. Even if you use the other point for the equation (1 = 2(2) +b), you should get the same answer of -3.
