The slope is 5 cuz y=mx+b, m referring to the slope and 5 is m in this instance
Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3 
x = -44/19
1. 4800-2000=2800
This is the distance that the balloon needs to fall to reach an altitude of 2000 feet.
2. 2800/40=70
Distance/rate=time
The answer is 70 minutes.
2 Men have to be picked from the 12 Men : 12 C 2
= (12*11)/(2*1) = 66
1 Woman have to be picked from the 12 Women : 12 C 1
= (12)/(1) = 12
Total Number of ways = 66 * 12 = 792
792 ways.
