Answer: (4,1) and (8,2)
Step-by-step explanation: i did rise over run and it was fairly easy since the slope is a basic line that does have fractions or decimals
Step-by-step explanation:
We reflect We triangle across both axis so the x and y values will both switch.
Our triangle is originally in the second quadrant but then go to the 4the after we reflect it.
Second Quadrant are

<em><u>original </u></em><em><u>price </u></em><em><u>=</u></em><em><u> </u></em><em><u>final </u></em><em><u>price</u></em><em><u>+</u></em><em><u> </u></em><em><u>decrease</u></em><em><u> </u></em><em><u>percent</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>final </u></em><em><u>price</u></em>
original price = $90 +80% ×$90
original price = $90+80/100 ×$90
original price= $90+$72
original price= $162
Answer:
C.
Step-by-step explanation:
x is bisecting the baseline (cutting it in 2 halves of 6).
the third angle in the main overall triangle is 60 degrees.
remember, all angles in a triangle always add up to 180 degrees.
so, 180 - 60 - 60 = 60.
that means that all 3 angles are of equal size (60). and that means that all 3 sides must have the same length.
=> y = 12
and now using Pythagoras to calculate the height (x) of the triangle :
y² = x² + 6² (remember, this side is only half the baseline)
12² = x² + 6²
144 = x² + 36
x² = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)
