Answer:

Part 1) 3 --------> $3\frac{3}{7}$ ÷ $1\frac{1}{7}$

Part 2) -3 -------> $-2\frac{2}{5}$ ÷ $\frac{4}{5}$

Part 3) 2 --------> $-12.2$ ÷ $-6.1$

Part 4) -2 -------> $-16$ ÷ $8$

Step-by-step explanation:

Part 1) we have

$3\frac{3}{7}$ ÷ $1\frac{1}{7}$

Convert mixed number to an improper fraction

$3\frac{3}{7}=\frac{3*7+3}{7}=\frac{24}{7}$

$1\frac{1}{7}=\frac{1*7+1}{7}=\frac{8}{7}$

Substitute

The quotient is equal to

$(\frac{24}{7})/(\frac{8}{7})=\frac{24}{8}=3$

Part 2)

we have

$-2\frac{2}{5}$ ÷ $\frac{4}{5}$

Convert mixed number to an improper fraction

$-2\frac{2}{5}=-\frac{2*5+2}{5}=-\frac{12}{5}$

Substitute

The quotient is equal to

$(-\frac{12}{5})/(\frac{4}{5})=-\frac{12}{4}=-3$

Part 3) we have

$-12.2$ ÷ $-6.1$

Convert decimal number to an improper fraction

$-12.2=(-12.2)*\frac{10}{10}=-\frac{122}{10}$

$-6.1=(-6.1)*\frac{10}{10}=-\frac{61}{10}$

Substitute

The quotient is equal to

$(-\frac{122}{10})/(-\frac{61}{10})=\frac{122}{61}=2$

Part 4) we have

$-16$ ÷ $8$

Remember that

$-16=-8*2$

Substitute

The quotient is equal to

$(-8*2)/(8)=-2$

Write a quadratic function with zeros -3 and 6.<br> Answer is in standard form.

Sergeu [11.5K]

1. Write the factors
(x+3)(x-6) = 0

2. Multiply the factors to get the answer in standard form
x^2 + 3x - 6x - 18 = 0

3. Simplify
x^2 - 3x - 18 = 0
