<h3>Answer:  2</h3>

Work Shown:

g(x) = x^2 - x

g(2) = 2^2 - 2 ... replace every x with 2

g(2) = 4 - 2

g(2) = 2

In this case, we won't use f(x)

Answer:

  • Jacob: 4
  • his mother: 39

Step-by-step explanation:

Let J and M represent the current ages of Jacob and his Mother.

<u>currently</u>:

  M = 3 +9J

<u>in 11 years</u>:

  M+11 = 5 +3(J+11)

Using the first equation to substitute for M in the second, we have ...

  (3 +9J) +11 = 5 +3(J +11) . . . . . substitute for M

  9J +14 = 3J +38 . . . . . . simplify

  6J + 24 . . . . . . . . . . subtract 3J+14

  J = 4 . . . . . . . . . . divide by 6

  M = 3 +9(4) = 39

Jacob is 4 and his mother is 39.

Find the simplified product
tekilochka [14]

Answer:

The answer is -30x^{2} \sqrt{2x}, or the first option.

The last option isn't correct for this answer, even though it is correct mathematically. This is because it wants the fully simplified version, so the 5o squared would turn into a 5 and a 2, with the 5 multiplying the -6, and the 2 remaining underneath the square root.
