D. 74⁻⁶ (74^-6)

Step-by-step explanation:

Looking at the expression, I remember the following: 1 over an exponent (as a fraction) is the same thing as a negative exponent. None of these answers involve an exponent except for D (although A does involve a negative number). So D, which is 74⁻⁶, is the answer here.

-3x2 - 16x + 12

-3x2 - 16x + 12 =

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

-96x + 12 that’s it;)

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]

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!
