Step-by-step explanation:

(3x² / 2 )° = 96° [ being corresponding angles ]

3x² = 192°

x² = 192/3

x² = 64

x² = (<u>+</u> 8) ²

Therefore x = +8 and -8

Hope it helps. :)

What is the slope of a line perpendicular to the line whose equation x+y=3. Fully simplify your answer
Tasya [4]

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

x + y =3\implies y=-x+3\implies y=\stackrel{\stackrel{m}{\downarrow }}{-1}x+3 \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} \\\\[-0.35em] ~\dotfill

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

Jorge has $138.22 in his savings account. He deposits $10.75 every week and withdraws $31.68 every four weeks. What will his bal
spayn [35]

Answer:

Pretty sure the answer is $160.86

Step-by-step explanation:

you start off by multiplying 10.75 x 8 because that's how much he'll deposit at the end of an 8 week spand.

adding 86+138.22= 224.22

then you subtract 31.68 two times from that as he withdraws 2 times in the 8 weeks, giving you the answer of 160.86.

hope this helps xx have a good day :)
