Answer:
Refer to picture for number line
Step-by-step explanation:
To solve this inequality, we want to isolate the variable. We can do this my getting like terms onto one side
[add both sides by 7]
[add both sides by 3x/2]
[multiply both sides by 2]
[add]
[divide both sides by 15]
[simplify]
Now that we have out inequality, we want to graph it. Since we know that , that means we have an open circle. Since x is less than, the arrow would be pointing left.
nCp = n! / (p!)*(n-p)!
so 12C8 = 12! / (8!)*(4!)
= 11880 / 24
= 495
ans is C
Answer: 24.75 m3
Step-by-step explanation: time everything all together
Answer:
x - 2 => x = 2
x² + 3ax - 2a
=> 2² + 3 × a × 2 - 2 × a
=> 4 + 6a - 2a
=> 4 + 4a
=> 4 ( 1 + a )
★ 1 + a = 0
a = -1
