Answer:
y = x for x ≥ 0 and y = - x for x < 0
Step-by-step explanation:
The absolute value function is written as y = |x| and it is defined as following
|x| = x when, x ≥ 0 and |x| = - x when, x < 0.
Therefore, the equations for the domain of x ≥ 0 is y = x
and the equation for the domain of x < 0 is y = - x (Answer)
A. The value of n can be any positive integer resulting in the same factor
Given
--- the right expression
Required
Possible values of n
Expand
Factorize
Factor out
<em>From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible</em>
<em></em>
The above also shows that n can take any positive value.
<em>Hence: (a) is correct</em>
So interest rate is 8% per annum
Principal amount = $3,006
Amount at end = $3,967.92
Time = 4yrs
interest money = ($3967.92 - $3006)
also equal to = 4 * (x/100) * $3,006
Where x is the interest rate per annum
So, 4 * (x/100) * $3,006 = ($3967.92 - $3006)
x = 8%

Oliver has 6 cupcakes
Lily has 2 cupcakes
Multiply 2 by 3 because Oliver has 3 times Lily
2 times 3 equals 6
