Answer:
193650
Step-by-step explanation:
Since the cost must be no more than 387$, you can substitute that number instead of y to get 387 = 0.002x - 0.30. you can add 0.30 to both sides to get 387.3 = 0.002x
Then you can divide both sides by 0.002 to get 387.3/0.002 = 193650
Answer:
Option C
x²+ 2x -24=0
x²+6x-4x-24= 0
x(x+6) -4(x+6) = 0
(x+6)(x-4) = 0
x= -6 and 4
Therefore, for x = 4 and -6 , the above given equation is true.
Step-by-step explanation:
percentage
current number/total number * 100
150/400*100 is 37.5%
<h3>The medians does'nt support the conclusion</h3>
<em><u>Solution:</u></em>
Given that,
Robin's scores: 99, 108, 102, 107, 119
Order the number from least to greatest
99, 102, 107, 108, 119
Median is the middle value of data set
Median is 107
Evelyn's scores: 125, 137, 138, 145, 145
Order the number from least to greatest
125, 137, 138, 145, 145
Medain is 138
The median of Evelyn's scores is greater than the median of Robin's
Therefore, the medians does'nt support the conclusion.
Answer:
Step-by-step explanation:
Given g (x) =
and
, we are to find 
First we need to get 

Hence 
Also given f(x) = x and g(x) = 1/x, we are to find 


For the pair of function f(x) = 2/x and g(x) = 2/x
f(g(x)) = f(2/x)
f(2/x) = 2/(2/x)
f(2/x) = 2*x/2
f(2/x) = x
Hence f(g(x)) = x
For the pair of function f(x) = x-2/3 and g(x) = 2-3x
f(g(x)) = f(2-3x)
f(2-3x) = (2-3x-2)/3
f(2-3x) = -3x/3
f(2-3x) = -x
f(g(x)) = -x for the pair of function
For the pair of function f(x) = x/2 - 2 and g(x) = x/2 + 2
f(g(x)) = f(x/2 + 2)
f(x/2 + 2) = f((x+4)/2)
f((x+4)/2) = [(x+4)/2]/2 - 2
f((x+4)/2) = (x+4)/4 - 2
find the LCM
f((x+4)/2) = [(x+4)-8]/4
f((x+4)/2) = (x-4)/4
Hence f(g(x)) for the pair of function is (x-4)/4
