Of course not.
' f(x) ' is the description of a function,and ' g(x) ' is the description of
a function. There are an infinite number of different possible functions,
so f(x) and g(x) are usually not the same one.
f(x) is equal to g(x) for any 'x' only when the two descriptions are the
same function. Otherwise f(x) is equal to g(x) only at the points where
their graphs intersect.
Answer:
See the step by step for explanation and answer
Step-by-step explanation:
The first function is a sin function with an amplitude of 2, and a period of 4pi. The -1 moves it down from its original position 1 unit. There is no phase shift here. The normal period of a sin function is 2pi, which means that one revoution of the graph (one Up-down-up to put it in simplest terms) starts at 0 and ends at 2pi. The x/2 means that the value to consider for the period change is 1/2. The formula to solve for a period change is 2pi/that value (most books call it b). So we have 2pi/(1/2), which algebraically solves to 4pi. That means that one up-down-up of the function starts at 0 and ends at 4pi.
That second function doesn't have a b value, so its period is still 2pi. The -5, however, moves the whole graph down 5 units from the original position (which is 4 units below the first graph). The second function also has an amplitude of 2. I hope this helps a bit!
Answer:
102 and 109
Step-by-step explanation:
create an equation to solve:
(x-7) + x = 225
2x -7 = 225
<u> +7 +7</u><u> </u><u> </u> add 7 to both sides
<u>2x</u> = <u>218</u>
2 2 divide both sides by 2
x = 109
<u>109 is the first number</u>
then you solve for the other number
x-7= ?
109 - 7 = 102
<u>102 is the 2nd number</u>
Answer:
#6 is 17 days
Step-by-step explanation:
This is how I answered it
1) 2750 = 550 + 125x
2) subtract 550 from each side
2750-550=2200
so the left over equation is:
2200 = 125x
3) divide each side by 125 to get x by itself
2200÷125= 17.6
4) you are left with: x = 17 days

The question you to divide 50 by 6.
It is the only way to get the number of times 6 goes into 50.
50/6=8 Remainder 2
