Answer:
$43.20
Step-by-step explanation:
A swimsuit that originally cost $90 before any discount is on sale for 20% off.
X = price of swimsuit
X = 90
20% off = 90 * 0.8 = 72
The swimsuit is then put on clearance for an additional 40 % off the sale price.
72 * 0.6 = 43.2
what is the final price?
$43.20
The answer is the first option: it has the same domain as the function f(x) = - √(-x).
The domain is the set of x-values for which the function is defined.
The square root function is defined only for zero and positve values.
- x is positive when x negative.
So the domain for - √(-x) and √(-x) are the same: x less than or equal to zero.
16/20 = 8(2)/10(2) = 8/10. 8/10 can also be further reduced to 4/5.
