Solve each inequality and graph it’s solution. Help pls
1 answer:
1) 0 > 3x - 3 - 6
-3 - 6 = -9
0>3x - 9
+9
9 > 3x
/3
x < 3
You should place an open circle on 3 with the arrow going left
<-----o
2) 4x + 1 - 1 ≥ - 8
1 - 1 = 0
4x ≥ - 8
Divide each side by 4
x ≥ -2
You should place a closed circle on the -2 with the arrow going right
----->
3) -1 ≤ 2n + 4 - 5
4 - 5 = -1
-1 ≤ 2n - 1
+1
0 ≤ 2n
Divide by 2
n ≥ 0
You should place a closed circle on the 0 with the arrow going right
---->
4) -6 > 5n + 5 + 4
5 + 4 = 9
-6 > 5n + 9
Subtract 9 from each side
-15 > 5n
Divide each side by 5
n < -3
You should place an open circle on the -3 with the arrow going left
<------o
5) 0 ≤ 2n + 3n
2n + 3n = 5n
0 ≤ 5n
Divide each side by 5
n ≥ 0
You should place a closed circle on the 0 with the arrow going right
------>
6) 2p - 4p ≤ -2
2p - 4p = -2p
-2p ≤ -2
Divide each side by -2
p ≥ 1
You should place a closed circle on the 1 with the arrow going right
o----->

Answer:
1004.8 in³
Step-by-step explanation:
d = 2r => r = d/2 = 16in/2 = 8 inches
V = Ab×h
= π·r²×h
= 3.14·(8in)²×5in
= 1004
Answer:
No, i dont agree as 1/3 in percentage is 33%
