HELP ON #2 PLEASEEE!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

ok so i think it is H

Step-by-step explanation:

Answer:

H, would be your answer.

Step-by-step explanation:

Solving the equation in the question...

3t - 8 = 4

3t - 8 + 8 = 4 + 8

3t / 3 = 12 / 3

t = 4

So, none of the equations once solved should equal 4, to not be equivelent.

F) 3t = 12

3t / 3 = 12 / 2

t = 4

T is 4 so this is not the right answer

G) t = 4

T is 4 so this is not the right answer

H) t - 8 = 1.33(4/3 in decimal form)

t - 8 + 8 = 1.33 + 8

t = 9.33

T does not equal 4 so this is the correct answer.

J) t = 8/3 + 4/3

t = 12/3

t = 4

In this option T is still 4 so this is not the correct answer.

So, therefore your answer would be H, because it is the only one that does not equal 4.

Hope this helps!

Find the domain and range of the following graph.

Answers

Remember that the domain is the set of all the x terms.

So in the graph shown here, notice that the x terms seem to be increasing in both a positive and negative direction and there seems to be no limit to how large or how small the x terms can get. So the x terms can be all positive and negative numbers, including decimals and fractions.

In other words, the x terms can be All Real Numbers.

So the domain is equal to the set of all real numbers or R.

The range is the set of all the y terms.

Notice that all the y terms are less than or equal to 9.

So the range is {y: y ≤ 9}.
