Which relation is a function​

Mathematics
1 answer:
erma4kov [3.2K]3 years ago
8 0

Answer:

Top left one on the attached, must be option A

Step-by-step explanation:

A function has to have unique input values and for each input value has to have an output value.

Analyzing the graphs we can see that only one of them is a function- top left one

All the others have repeat input values, therefore are not functions

All those points marked with red circle

How do you do this?!<br> (2w-1)/(4)=(2-w)
nikklg [1K]

Answer:

w = 3 is your answer.

Step-by-step explanation:

You want to get w by itself.

<em>(2w - 1)/(4) = 2 - w         </em><u>You will add the w on both sides.</u>

<em>(3w - 1)/(4) = 2                </em><u>You will multiply 4 on both sides.</u>

<em>3w - 1 = 8                       </em><u>You will add 1 on both sides.</u>

<em>3w = 9                            </em><u>You will divide 3 on both sides.</u>

w = 3 is your answer.

Simplify the following expression by combining like terms and factoring. 2(x-6)+4(2x+1)+3
Shkiper50 [21]

Answer:

5(2x - 1)

Step-by-step explanation:

Given

2(x - 6) + 4(2x + 1) + 3 ← distribute both parenthesis

= 2x - 12 + 8x + 4 + 3 ← collect like terms

= (2x + 8x) + (- 12 + 4 + 3)

= 10x + (- 5)

= 10x - 5 ← factor out 5 from each term

= 5(2x - 1) ← in factored form
