Consider the equation y = -2x + 5. Create a table of five ordered pairs that satisfy the equation. What is the y-intercept of th

Tatiana [17]

Answer: option d.

Step-by-step explanation:

To create a table of five ordered pairs that satisfy the equation, you need to give values to the variable "x" and substitute these into the function to find the corresponding value of "y":

For $x=-2$

$y = -2(-2) + 5=9$

For $x=-1$

$y = -2(-1) + 5=7$

For $x=0$

$y = -2(0) + 5=5$

For $x=1$

$y = -2(1) + 5=3$

For $x=2$

$y = -2(2) + 5=1$

Then, you can make the table:

x -2 -1 0 1 2

y 9 7 5 3 1

To find the x-intercept, substitute $y=0$ into the function and solve for "x". Then:

$0 = -2x + 5\\\\x=\frac{-5}{-2}\\\\x=\frac{5}2}$

This is: ( $\frac{5}{2}$ , 0)

To find the y-intercept, substitute $x=0$ into the function and solve for "y". Then:

$y= -2(0) + 5\\\\y=5$

This is: (0,5)

How many one-to-one correspondences are there between two sets with 6 elements each?

WINSTONCH [101]

Answer:

6 * 5 * 4 * 3 * 2 * 1, i.e. 6! or 720. Of course, since both sets have the same number of elements, you can't have one-to-one without being onto, aka a surjection, so “one to one correspondence” is the right term (or bijection—merci, M.
