Which of the following is the correct input-output table for the function? Y=6x+5

Answers

Answer:

The answer is table b.

Step-by-step explanation:

To solve this question,  you can mentally calculate each value of each table, until you come to a wrong one. When you do, move on. To give an example:

Table a:

x input value: 1

y output value: 12

y true output value: 11

I did this by substituting the value of x in the equation given, so:

y = 6(1) + 5 = 11

Simply do this in your mind for each value, and you'll get your answer if every value in the table is correct!

Please only answer if you can help!!

Nick poured 3/4 fluid ounce of vineger into each ten 1-fluid -ounce test tubes test tubes to use in an experiment for Science Night each circle represent 1 fluid ounce how many fluid ounces did nick pour

Answers

Answer:

7.5 fluid ounces

Step-by-step explanation:

Fraction of fluid ounce poured into each test tube

Number of test tubes filled = 10

The number of fluid ounces poured is the product of the amount poured into each test tube and the number of test tubes filled

Therefore, total amount poured :

(3/4 fluid ounces) * 10

0.75 * 10

= 7.5 fluid ounces

Answer:

[tex]x=44[/tex]

m∠1=118°

m∠2=62°

Step-by-step explanation:

Part A: They are supplementary angles, so

[tex]2x+30+62=180[/tex]

Simplify like terms,

[tex]2x+92=180[/tex]

We subtract 92,

[tex]2x=88[/tex]

Divide by 2,

[tex]x=44[/tex]

Part B:

[tex]m[/tex]∠[tex]1=2x+30[/tex] because ∠2 is vertical to 2x+30.

Plug in 44 for x,

[tex]m[/tex]∠[tex]1=2(44)+30[/tex]

Simplify,

[tex]m[/tex]∠[tex]1=118[/tex]

[tex]m[/tex]∠[tex]2=62[/tex]° because it is a vertical angle to the 62° angle.

Answer:

Solution given:

2x+30+62=180°[linear pair]

2x=180-92°

x=88/2=44°

Now,

<1=2x+30=2×44+30=118°[vertically opposite angle]

<2=62°[vertically opposite angle]

[vertically opposite angle]

Answers

Answer: −(3x−2)(x+6)

Step-by-step explanation:

We know it's factored because...

−(3x−2)(x+6)

If we multiply, then we get what we started with.

-3x * x = -3x^2

2 * x = 2x

-3x * 6 = -18x

2 * 6 = 12

-3x^2 - 18x + 2x + 12

-3x^2 - 16x + 12
