Answer:

x = 2

Step-by-step explanation:

8x = 4x + 8

Subtract 4x from each side

8x-4x = 4x-4x + 8

4x = 8

Divide each side by 4

4x/4 = 8/4

x = 2

Answer:

= 2

Step-by-step explanation:

Subtract 4x4x from both sides.

8x-4x=88x−4x=8

2 Simplify 8x-4x8x−4x to 4x4x.

4x=84x=8

3 Divide both sides by 44.

x=\frac{8}{4}x=

4 Simplify \frac{8}{4}

to 22.

x=2x=2

Which of the following is the quotient of b and a?

vlabodo [156]

$\bf 19^{\frac{7}{4}}\cdot \sqrt[a]{19^b}=19^{\frac{5}{2}}\sqrt{19}\\\\
-----------------------------\\\\
a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-----------------------------\\\\
thus\qquad 19^{\frac{7}{4}}\cdot 19^{\frac{b}{a}}=19^{\frac{5}{2}}\cdot 19^{\frac{1}{2}}\implies 19^{\frac{7}{4}+\frac{b}{a}}=19^{\frac{5}{2}+\frac{1}{2}}
\\\\\\
$

$\bf 19^{\frac{7}{4}+\frac{b}{a}}=19^{\frac{6}{2}}\implies 19^{\frac{7}{4}+\frac{b}{a}}=19^3\impliedby 
\begin{array}{llll}
\textit{same base, thus}\\
\textit{exponents must be the same}
\end{array}
\\\\\\
\cfrac{7}{4}+\cfrac{b}{a}=3\implies \cfrac{b}{a}=3-\cfrac{7}{4}$
