Part A: This data does represent a function because no value of x is repeated.
Part B: If x = 6 for the relation f(x) = 7x - 15, then f(x) will equal 27. The function f(x) = 7x - 15 will have the greater value
Part C: If f(x) is equal to 6 then x will equal 3

For the linear system :

r+t = 20 and 5(r+t) = 150

If you sub in the first equation into the second, you will get: 100 = 150, which is incorrect

It means the system does NOT have solutions.

Answer will be the last choice

Does this graph represent a function? Why or why not?
artcher [175]

Answer:

Yes, this graph represents a function.

Functions can have a maximum of one y-value for every x-value. On a graph, this means it passes the vertical line test.

Step-by-step explanation:

The vertical line test is when a vertical line is passed though the graph. If at any point the vertical line touch more than one point on the graph, the graph is not a function. Vertical line test is also known as VLT.

Complete the solution table from left to right for the quadratic function. (I did not select an answer, that was a mistake) Than
Karo-lina-s [1.5K]

Answer: OPTION D

Step-by-step explanation:

To complete the table, you need to substitute the values of "x" given in the table into the quadratic equation y=x^{2}-x-6 to obtain the corresponding value of "y".

Then:

When x=-5 :

y=(-5)^{2}-(-5)-6

y=24

When x=-3 :

y=(-3)^{2}-(-3)-6

y=6

When x=-1 :

y=(-1)^{2}-(-1)-6

y=-4

When x=2 :

y=(2)^{2}-(2)-6

y=-4
