You do keep, change, and flip when dividing fractions.

Keep 4/6, change the division sign into times, and flip 4/12 into 12/5.

4/6 x 12/4 =

Just multiply across.

(4 x 12)/(6 x 4) = 48 / 24 = 2.

The answer is 2.

Plz! I need this to be answered! Solve − 3/8 c ≥ 9

ExtremeBDS [4]

$-\dfrac{3}{8}c \geq 9$

First we need to multiply all the inequality by 8 to get rid of the denominator

$-\dfrac{3}{8}c \geq 9|\times 8\\-3c\geq 72$

Now we need to divide all inequality by -3

$-3c\geq 72|\div(-3)$

When dividing or multiplying an inequality by a negative number the inequality sign changes, so

$c\leq -24$

Answer: c ≤ -24

Solve for the roots in the equation below. In your final answer, include each of the necessary steps and calculations. Hint: Use

QveST [7]

$\bf 27\implies 3^3\\\\
i^3\implies i\cdot i\cdot i\implies i^2\cdot i\implies -1\cdot i\implies -i\\\\
-----------------------------\\\\
x^3-27i=0\implies x^3+3^3(-i)=0\implies x^3+(3^3i^3)=0
\\\\\\
x^3+(3i)^3=0\\\\
-----------------------------\\\\
\textit{difference of cubes}
\\ \quad \\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3\\\\
-----------------------------\\\\$

$\bf (x+3i)[x^2-3ix+(3i)^2]=0\implies 
\begin{cases}
x+3i=0\implies \boxed{x=-3i}\\\\
x^2-3ix+(3i)^2=0
\end{cases}
\\\\\\
\textit{now, for the second one, we'd need the quadratic formula}
\\\\\\
x^2-3ix+(3i)^2=0\implies x^2-3ix+(3^2i^2)=0
$

$\bf x^2-3ix+(-9)=0\implies x^2-3ix-9=0
\\\\\\
\textit{quadratic formula}\\\\
x= \cfrac{ - {{ b}} \pm \sqrt { {{ b}}^2 -4{{ a}}{{ c}}}}{2{{ a}}}\implies x=\cfrac{3i\pm\sqrt{(-3i)^2-4(1)(-9)}}{2(1)}
\\\\\\
x=\cfrac{3i\pm\sqrt{(-3)^2i^2+36}}{2}\implies x=\cfrac{3i\pm\sqrt{-9+36}}{2}
\\\\\\
x=\cfrac{3i\pm\sqrt{27}}{2}\implies \boxed{x=\cfrac{3i\pm 3\sqrt{3}}{2}}$

X = {(2, 3), (2, 4), (2, 5), (2, 6)} The domain of x is

mina [271]

Answer: Domain: {2}

Step-by-step explanation:

1. By definition, the domain is the input value, this means that it is the x-value of a function.

2. Therefore, keeping the definition above on mind, you have that the domain of x is the x-value of each ordered pair.

3. Then, given x = {(2, 3), (2, 4), (2, 5), (2, 6)}, you can see that x-value of each ordered pair is 2. Therefore, you can conclude that the domain of x is:

Domain:{2}
