X= 16 - 4x 3x + 4y= 8 using the system of linear equations by substitution. Help asap please

7nadin3 [17]

Answer:

x = 4.31 and y = -1.23 (to the nearest hundredth).

Step-by-step explanation:

y = 16 - 4x

3x + 4y = 8

Substitute y = 16 - 4x in the second equation:-

3x + 4(16 - 4x) = 8

3x + 64 - 16x = 8

-13x = 8 - 64 = -56

x = -56 / -1 3 = 4.308

Plugging this value into the first equation:-

y = 16 - 4(4.308)

= -1.23

What is the slope of a line perpendicular to the line whose equation is 5x - y = -7.

BARSIC [14]

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

$5x-y=-7\implies 5x-y+7=0 \\\\\\ \stackrel{\stackrel{m}{\downarrow }}{5} x+7=y\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

so a line perpendicular to that one above will have a slope of

$\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{5\implies \cfrac{5}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{5}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{5}}}$
