Answer:
Step-by-step explanation:
y = 5x - 4
y = 6x $\Rightarrow$ x = y/6
y = 5*y/6 - 4
y = 5y/6 - 4
6y = 5y - 24
y = -24.
So, x = -4
44 students would choose computer games because 20+14+24=54 students in total 44 + 14=54
0.25x² + 8.5 - 17 = 0
1)
a = 0.25
b = 8.5
c = -17
2)
- 8.5 ± √(8.5)²-4(0.25) (-17)
------------------------------------------
2(0.25)
3)
-34 ± √1428
----------------------
2
4)
-35.894 and 35.894
The answer is g=2
6g-3.5=8.5
6g+3.5=+3.5
6g=12
6g 6g
g=2
10 x 1 =10 0 x 0 =90 grorgi6
