thus $\bf a+\cfrac{1}{a}=\cfrac{61}{30}$

solve for "a"

Write the slope-intercept form of an equation that passes

Hunter-Best [27]

Answer:

$y = \frac{4}{3}x-5$

Step-by-step explanation:

As the line is perpendicular to $y=-\frac{3}{4} x + 2$ , we know that the slope of the line is $\frac{4}{3}$ . As it passes through $(3, - 1)$ , we know that it should be $y = \frac{4}{3}x-5$ .

How to solve this equation

mariarad [96]

$\bf \sqrt{5x+19}-4=3x-15
\\\\
\sqrt{5x+19}=3x-15+4\\\\ \sqrt{5x+19}=3x-11\leftarrow \textit{square both sides}
\\\\
(\sqrt{5x+19})^2=(3x-11)^2
\\\\
5x+19=(3x-11)^2\qquad 
\begin{cases}
(3x-11)^2\to (3x-11)(3x-11)\\
 --------------\\
\textit{or use FOIL to expand it}
\end{cases}$

then solve for "x"

In one hour, 17 cars drive through an intersection. Two-fifths of the 17 cars fail to come to a complete stop at the stop sign.

Rasek [7]

Answer:

Step-by-step explanation:

When you have a number (17) and want to know some fraction (2/5) of that number, you should multiply the number by the fraction.

17 * (2/5)

= (17*2)/5

= 34/5

= 6.8

You can then round this number up --> about 7 cars.
