10 1/2
how I got that:
so the whole number stays the same
5/10
simplifies to
1/2
:-)
Answer:
the scale factor is 6
Step-by-step explanation:
25x² + 4y² + 50x - 24y - 39 = 0
25x² + 50x + 4y² - 24y - 39 = 0
25x² + 50x - 39 = 0 4y² - 24y - 39 = 0
x = <u>-b + √b² - 4ac</u> y<u> </u>= <u>-b + √b² - 4ac</u>
2a 2a
x = <u>-50 + √(-50)² - 4(25)(-39)</u> y =<u> -(-24) + √-(-24)² - 4(4)(-39)</u>
2(25) 2(4)
x = <u>-50 + √2500 + 3900</u> y = <u>24 + √-576 + 624</u>
50 8
x = <u>-50 + √6400</u> y =<u> 24 + √48
</u> 50 8
x = <u>-50 + 80 </u> y =<u> 24 + √16 × 3</u>
50 8
x = <u>-50 + 80</u> y = <u>24 + √16 √3
</u> 50<u> </u> 8 <u>
</u>x<u> </u>= -<u>50 + 80 </u> y = <u>24 + 4 √3</u>
50 8
x = <u>-50 + 80</u><u> </u> <u /> y = <u>24 + 4 √3 </u>
50 8
x =<u> -50 + 80</u> x = <u>-50 - 80</u> y = <u>24 + 4 √3</u> y = <u>24 - 4 √3</u>
50 50 8 8
x = <u>30</u> x = -<u>130</u> y = <u>28 √3</u> y = <u>20 √3</u>
50 50 8 8
x = <u>3</u> x = <u>-13</u> y = <u>28 √3</u> y = <u>20 √3</u>
5 5 8 8
(x, y) = (<u>3</u>, <u>26 √3</u>) (x, y) = (<u>-13</u>, <u>20 √3 </u>)
