Answer:

1) $= 10 \frac{2}{5} = \frac{52}{5}$

2) $= \frac{252}{25} = 10 \frac{2}{25}$

Step-by-step explanation:

$6 \frac{4}{5} + 3 \frac{3}{5} \\ (6 + 3) + ( \frac{4}{5} + \frac{3}{5} ) \\ 9 + \frac{7}{5} = 9 + 1 \frac{2}{5} \\ 9 + 1 + \frac{2}{5} = 10 + \frac{2}{5}$

$\boxed{\green{= 10 \frac{2}{5} = \frac{52}{5}}}$

•◇•◇•◇•◇•◇•◇•◇•◇•◇•◇•

$2 \frac{4}{5} \times 9 \frac{2}{5} \\ \frac{14}{5} \times 9 \times \frac{2}{5 }$

$\boxed{\green{ = \frac{252}{25} = 10 \frac{2}{25}}}$

Is the function continuous at x = -17

Pavlova-9 [17]

For a function to be continuous at an x-value, say -17, you need to make sure two things line up:

The limit from the left equals the limit from the right.

$\lim_{x \to -17^{-}} f(x) = \lim_{x \to -17^{+}} f(x)$

This limit equals the functions value.

$\lim_{x \to -17} f(x) = f(-17)$

The left hand limit involves the first piece, f(x) = 20x + 1:

$\begin{aligned} \lim_{x \to -17^{-}} f(x) &= \lim_{x \to -17^{-}} (20x+1)\\[0.5em]&= 20(-17)+1\\[0.5em]&= -339\endaligned}$

The right hand limit invovles the second piece, f(x) = -10x^2:

$\begin{aligned} \lim_{x \to -17^{+}} f(x) &= \lim_{x \to -17^{+}} (-10x^2)\\[0.5em]&= -10\cdot (-17)^2\\[0.5em]&= -2890\endaligned}$

Since the two one-sided limits don't match, the function is not continuous at x=-17.
