Given the function, f(x) = 9 - x :
To evaluate f(4), we must substitute 4 into the given function as an input value for x:
f(4) = 9 - 4
f(4) = 5
Therefore, f(4) = 5.
(Are you saying the king case is an additional 12% of $84? I think you should word the question a bit more clearly).
12% = 12/100 = 0.12 multiplied by $84 = $10.08 = $84 + $10.08 = $94.08
We have $94.08 so far (king case and camera price combined).
Tax is 6%, so 6/100 = 0.06 multiplied by $94.08 = $5.64
Add $5.64 to the $94.08 total we calculated.
$94.08 + $5.64 = $99.72 <=== this is our total cost plus tax.
took the test. answer is logb(y^4x^3), or A.
Answer:
Set builder notation: {a | a ≥ -21}
Interval notation: [-21, ∞)
Step-by-step explanation:
A set represents a collection of things, objects, or numbers. A set builder notation is in the form y = {x | x is an odd number between 8 and 10}, which means y contains all the odd numbers between 8 and 10.
Interval notation is a way to define a set of numbers between a lower limit and an upper limit using end-point values. for example (8, 20) means numbers between 8 and 20.
Given -3a-15≤-2a+6; solving :
-3a - 15 ≤ -2a + 6
-3a + 2a ≤ 6 + 15
-a ≤ 21
dividing through by -1:
a ≥ -21
The solution is:
Set builder notation: {a | a ≥ -21}
Interval notation: [-21, ∞)
