Answer:
(14 groups)
14 divided by 7 = 2
Therefore 14 is your answer
Step-by-step explanation:
lol that's all I got
All others did not satisfy the inequality simultaneously except #4 and #6
For #4:
2 < 5(1) + 2 i.e. 2 < 7 (true)
2 >= 1/2(1) + 1 i.e. 2 >= 3/2 (true)
For #6
2 < 5(2) + 2 i.e. 2 < 12 (true)
2 >= 1/2(2) + 1 i.e. 2 >= 2
Answer: y=0,5x²-x-1,5.
Step-by-step explanation:
We summarize (1) and (3):
Substitute b=-1 into (2):
From (5) subtract (4):
Substitute a=0,5 into (4):
Hense:
y=0,5x²-x-1,5.
Answer:
The answer should be 3 cubic cm
Step-by-step explanation:
First you have to get the area of the right triangle base 1/2 bh. That would be 2x3/2=3
To find volume, you plug the area in the volume formula
v=1/3 ah
v=1/3 (3)(3)
1/3(9) would be 3 cubic cm
Let's use the variable "r" to represent the investment rate of the stocks:
2r(500) + r(800) = 45
1000r + 800r = 45
1800r = 45
r = 0.025
2r = 0.05
The $500 is invested at 5%
