Hey there!

Okay, so when you get a problem like this, all you need to do in insert the given value into the function and solve.

For example:

As you can see, they state that <em>(a) = 27, </em>so you insert 27 in for a in the function and it will look like this:

h(27) = 3(27) + 5

Now you solve on the right side of the equal sign:

3(27) = 81 (you multiply them)

81 + 5 = 86

When you plug the value of 27 in for a in this function, your output is equal to 86.

Answer:

Option A, \frac{1}{7}

Step-by-step explanation:

<u>Step 1:  Determine the numbers that are multiples of 3</u>

8 → Not a multiple of 3

9 → Multiple of 3

14 → Not a multiple of 3

19 → Not a multiple of 3

25 → Not a multiple of 3

34 → Not a multiple of 3

38 → Not a multiple of 3

<u>Step 2:  Determine the probability of chosing a multiple of 3</u>

Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:  

\frac{(1\ multiple\ of\ 3)}{7\ total\ numbers}

\frac{1}{7}

Answer: Option A, \frac{1}{7}

Which is an equation of the line containing the points (2, 5) and (4, 4) in standard form?
Gala2k [10]

Answer:

  x +2y = 12

Step-by-step explanation:

Try the given points in the given equations and see what works.

  -2x + 5y at (2, 5) is -2(2) +5(5) = 21 ≠ 12

) +)   2x + y at (2, 5) = 2(2) +(5) = 9 ≠ 12

  x + 2y at (2, 5) = 2 +2(5) = 12 . . . . . goes through first point

  x + 2y at (4, 4) = 4 + 2(4) = 12 . . . . goes through second point

__

You know the answer at this point, so the next check is just for "completeness." It is not necessary to properly answer the question.

  -x +2y at (2, 5) = -(2) +2(5) = 8 . . . . goes through first point

  -x +2y at (4, 4) = -(4) + 4(4) = 4 ≠ 8 . . . does not go through second point
