Step-by-step explanation:
2x²+3x-2=0
(2x-1)(x+2)
x+2=0
x=-2 (no, because x must be >0)
2x-1=0
2x=1
x=½ (yes, because x>0)
B. 5
Each row across (left to right) adds up to 43
Answer:
Step-by-step explanation:
- 2x − y > 2
- 2x - y + y - 2 > 2 + y - 2
- 2x - 2 > y
- y < 2x - 2
Solution is the points below the line y = 2x - 2
<u>Correct option is:</u>
Answer:
24
Step-by-step explanation:
if 12 cars are half of his collection, his entire collection is 12(2) which equals 24
P(picking one defective) = 3/10
P(picking a 2nd defective) = 2/9
P(1 and 2 defective) = 3/10 x 2/9 = 6/90 = 0.066
Second method using combination:
³C₂ / ¹⁰C₂ = 1/15 = 0.066
