Which of these ordered pairs are points on the graph of y = 3x - 6?

Mathematics
1 answer:
Stells [14]3 years ago
8 0

Answer:

D

Step-by-step explanation:

Check all of the pairs to see if they match up

1 = 3(2) -6

1 = 6-6

1 ≠ 0

-3 = 3(-1) - 6

-3 = -3 - 6

-3 ≠ -9

3 = 3(-3) -6

3 = -9 -6

3 ≠ -15

12 = 3(6) -6

12 = 18 - 6

12 = 12

Last one is the only one that matches

Which of the following trigonometric fuuctions has a range of apply all real numbers? Select all that apply.
Kryger [21]

Answer:

y=tan x and y=cotx

Step-by-step explanation:

We are given functions of all trignometric ratios and asked to find out which has range of all real numbers.  Let us discuss one by one

1. y =sinx:  False because -1≤sinx≤1 always

2. y=cosx:False because -1≤cosx≤1 always

3. y = tanx:  True because tanx can take any value

4. y=cot x: True because cots x can take any value

5. y = csc x:   False because this range does not lie between -1 and 1

6. y=sec xFalse because this range does not lie between -1 and 1

For which of these sets of data would all the points be displayed on a scatterplot if the window size on a regression calculator
Ivan

Answer:

Step-by-step explanation:

Oh, this is a lot easier than you made it sound, lol.

This is the correct answer:

The table with the following:

X=6,7,9,11,13,14

Y=27,33,39,49,58,71

Lol, I didn't realize that was all this was.

Anyways, the table that matches that is correct, that's actually a bit obvious. The numbers you gave me are parameters, a limit. The numbers for x per y have to fall between those numbers listed.
