Because your gonna elminate the loners and soon your going to substitute them for numbers
Part A)
The table doesn't represent y as a function of x.
Why? <span>One reason is that 1 or 3 is the first element in more than one ordered pair.
Part B)
f(x) = 10x + 20
f(120)= 10*120 + 20 = 1200 + 20 = 1220
</span><span>f(120) represents cost of boating for 120 hours.</span><span>
</span>
6h + 5h - 3j = 11h - 3j (all u can do is combine like terms...if they're not like terms, they cannot be combined)
Answer:
Concept: Binomial Multiplication
- (x-1)(x-9)
- x^2-9x-x+9
- x^2-10x+9
The correct question is
<span>Michael sold 2/3 of his CDs and purchased 16 more. If Michael has 25 CDs now, how many CDs did he have to begin with?
Let
x--------------> numbers of CDs Michael have to begin
if Michael sold (2/3)x-----------> </span><span>are pending to sell (1/3)x
we know that
(1/3)x+16=25--------> </span>(1/3)x=25-16-------> (1/3)x=9---------> x=27
the answer is 27 CDs
