Step-by-step explanation:
8=1,2,4,8.
12=1,2,3,4,6.
18=1,2,3,6,9.
so 2 is common and lowest in everyone.
answer is 2
Answer:
x=0
Step-by-step explanation:
(1): "^-2" was replaced by "^(-2)".
rearrange the equation: x/81^(-2)/729^1-x-(9^2*x)=0
STEP
1
:
1.1 9 = 32
(9)2 = (32)2 = 34
Equation at the end of step
1
:
x
(—————— ÷ (7291)-x)-(34•x) = 0
(81-2)
STEP
2
:
2.1 729 = 36
(729)1 = (36)1 = 36
Equation at the end of step
2
:
x
(—————— ÷ 36 - x) - 34x = 0
(81-2)
STEP
3
:
3.1 81 = 34
(81)-2 = (34)(-2) = (3)(-8)
Equation at the end of step
3
:
x
(——————— ÷ 36 - x) - 34x = 0
(3)(-8)
STEP
4
:
1
Divide x by ——
38
Equation at the end of step
4
:
38x
(——— - x) - 34x = 0
36
STEP
5
:
38x
Simplify ———
36
Dividing exponents:
5.1 38 divided by 36 = 3(8 - 6) = 32
Equation at the end of step
5
:
(9x - x) - 34x = 0
STEP
6
:
Equation at the end of step 6
-73x = 0
STEP
7
:
Solving a Single Variable Equation:
7.1 Solve : -73x = 0
Multiply both sides of the equation by (-1) : 73x = 0
Divide both sides of the equation by 73:
x = 0
One solution was found :
x=0
Answer: B, D, E
Step-by-step explanation:
Statement 1 cannot be true because f(1)<0.
Statement 2 might be true.
Statement 3 cannot be true because if f is continuous, then for some value between -1 and 0, f(x) is positive by the Intermediate Value Theorem.
Statement 4 might be true.
Statement 5 might be true
