5x + 2 > 7x - 1
In this scenario, we are solving the inequality.
What this means is that we would need to get x on one side in order to figure out what x is.
Solve:
5x + 2 > 7x - 1
Subtract 7x from both sides
-2x + 2 > -1
Subtract 2 on both sides
-2x > -3
Divide both sides by -2. Flip the inequality since you're dividing by a negative
x < 3/2
In interval notation it would be:
( -∞ , 3/2) or ( -∞ , 1.5)
Answer:
x = 1.5
Step-by-step explanation:
5x + 2 > 7x - 1
5x -7x = -1 -2 (move the terms to the same side, but change the sign on the term being transferred)
-2x = -3 (divide by -2 on both sides)
x = 1.5

If it says that all you have to do is write the first on top and the 2nd on the bottom
2,5, 6, 8, 14
Answer:
4.
Step-by-step explanation:
First work out the mean:
Mean = (2 + 5 + 6 + 8 + 14) / 5
= 35/5 = 7.
Now subtract the mean form each of the values:
2 - 7 = -5
5 - 7 = -2
6 - 7 = -1
8 - 7 = 1
7 - 14 = -7.
The squares of these are 25, 4, 1, 1, 49
Their sum = 25 + 4 + 1 + 1 + 49 = 80
Now divide this by 5 = 16.
Standard deviation is √16 = 4.
A. 4x - 2
B. 4x + 7
C. 4x+ 12
D.5x - 2
Answer:
The volume of the prism is 3 times the volume of the cone
Step-by-step explanation:
step 1
we know that
The area of the prism is given by the formula
----> equation A
where
B is the area of the circular base
h is the height of the prism
step 2
The area of the cone is given by the formula
----> equation B
where
B is the area of the circular base
h is the height of the cone
In this problem we have that they have the same height and same base area
so
substitute equation A in equation B
solve for V_p
therefore
The volume of the prism is 3 times the volume of the cone
