Does this table represent a function ? Why or why not

Answer:

C. No, because one x value corresponds to two different y values.

Step-by-step explanation:

We are given a table having value of x and y such that it forms a function.

Now, we know that a 'function' is a mapping from domain to the co-domain such that every value of the domain is mapped to a unique value of the co-domain.

According to our table, we can see that corresponding to the point x = 5, there are two different values y = 2 and y = 5.

So, this table does not represents a function.

Hence, option C is correct.

Example 4
Vesnalui [34]

Answer: Part a: b represents the base fee charged for the "house call" job

m is the hourly rate.

x is the number of hours at the job.

y represents the total cost for the job.

Part b:. The y-intercept is 65

The equation follows y=mx+b

Y= 42x + 65

Part c:. $275

Step-by-step explanation:

The difference between the two total costs, (Camilla 191 - Connor 107)

= $84. That is the rise. The run is the difference in time, 2 hours. 84/2 = 42.

m= 42

42 from 107 to find b, the base fee, 65 This is the y-intercept.

The equation is y= 42x + 65

Quick check using Camilla's bill: 191 = (42)(3) + 65

191 = 126 + 65 True!

Part C:

To find the total cost of the plumber's 5 hour job,

Y = 42(5) + 65

Y= 210 + 65

Y= $275

Simplify the expression below -3(10x + 4y) + 6(6x − 2y)
iren [92.7K]

Answer:

6x - 24y

Explanation:

Expand -3(10x + 4y): -30x - 12y

= \bold{-30x-12y+6\left(6x-2y\right)}

Simplify \bold{-30x-12y+6\left(6x-2y\right): \ 6x-24y}

= 6x - 24y

mestny [16]
C.  The Triangle Inequality Theorem States that any two sides of a triangle must be greater than the third side. It cannot be A because 35+40= 75, which is not greater than 75. It cannot be B because 40+30= 70, which is not greater than 75. It cannot be D because 35+40= 75, which is not greater than 80. It is C because 40+30= 70, which is greater than 65.
