Answer:

Step-by-step explanation:
The given expression is : 
We need to simplify the above expression.
We know that, 
or

So, the simplified form of the given expression is
. Hence, the correct option is (A).
Answer:
a = 8
Step-by-step explanation:
x-1 = 0
x = 1
let x³ + ax² -x -8 be p(x)
hence, p(1) = (1)³ + a(1)² -1 -8 = 0 (since, x-1 is a factor)
= 1 + a - 1-8
= a - 8 = 0
therefore, a = 8
Answer:
x=-4, y=2. (-4, 2).
Step-by-step explanation:
5x+6y=-8
-2x+8y=24
-----------------
2(5x+6y)=2(-8)
5(-2x+8y)=5(24)
-----------------------
10x+12y=-16
-10x+40y=120
---------------------
52y=104
y=104/52
y=2
5x+6(2)=-8
5x+12=-8
5x=-8-12
5x=-20
x=-20/5
x=-4
Answer:
Value = 500000 × (1.1^n)
$1,296,871
Step-by-step explanation:
a = 500000
r = 550000 ÷ 500000 = 1.1
1st term is the initial year:
n years after that is the "n+1"th term
Value = 500000 × (1.1^n)
n = 10
500000(1.1¹⁰)
1,296,871.23005
