For<br> x &lt; -2<br> f(x) =<br> -3x - 3<br> 6x – 28<br> for<br> Find f(5)
Lemur [1.5K]

Answer:

f(5) = 2

Step-by-step explanation:

To evaluate f(5), that is when x = 5 in the interval x ≥ 5

then

f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so

f(5) = 2

Sarah cut off 1/8 of a 48 inch piece of ribbon. Jane cut off 1/9 of a 36 inch piece of ribbon. They compared their cut pieces. W
Otrada [13]

Answer:

Sarah's, 2 inches.

Step-by-step explanation:

Given:

Sarah cut off 1/8 of a 48 inch piece of ribbon.

Jane cut off 1/9 of a 36 inch piece of ribbon.

Question asked:

Whose piece is longer ?

How much longer ?

Solution:

As Sarah cut off 1/8 of a 48 inch piece of ribbon, means she has cut piece of size:

\frac{1}{8} \ of \ 48\\\frac{1}{8} \times48 = \frac{48}{8} = 6\ inches

As Jane cut off 1/9 of a 36 inch piece of ribbon, means she has cut piece of size:

\frac{1}{9} \ of \ 36\\\frac{1}{9} \times36 = \frac{36}{9}  = 4 \ inches

As Sarah has 6 inches piece of ribbon and Jane has 4 inches piece of ribbon so Sarah's piece longer.

Now, to find it is how much longer we will subtract Jane's piece of ribbon from Sarah's piece of ribbon,

6 inches - 4 inches = 2 inches.

And hence,  Sarah's piece of ribbon is 2 inches longer than Jane's  piece of ribbon .

Find the missing factor x^2-11x+18=(x-2)( )
tia_tia [17]
I'd use synthetic div. here, with 2 as my divisor:

      ________________
2   /   1    -11    18
                  2   -18
     ----------------------------
         1     -9      0

Note that the coefficients of the missing factor are given here and are 1 and -9.  Thus, (x-9) is the missing factor.
