Answer:
21
Explanation:
To solve this problem, you substitute in the 5 for the x creating this equation: f(5)=6+3(5).
f(5)=15+6
f(5)=21
Answer: f(x) = -9x
Step-by-step explanation:
Remember that f(x) is the same thing as y.
y = 3x + 6x + 2y
First, combine like terms to get...
y = 9x + 2y
Then, subtract -2y from each side to get..
-y = 9x
Next, you divide by -1 and get...
y = -9x ,which is your answer
Hope this is helpful :)
So mean also translates to average so
the mean of 4 numbers is aprox
x=average
(x+x+x+x)/4=average
to increase x by 2 you add 2
x+2=average
(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2
you would have to increase the sum/total by 8 to make the numbers' averages' go up by 2
Answer:
This is incomplete, but i will answer it in a general way.
A function is something like y = f(x)
You can think in a function like a "machine", that eats an input (x) and transforms it into an output (y).
The functions have a rule: For all the possible inputs, the function can transform them into only one output.
This means that if we have for an input x1.
f(x1) = y1 and f(x1) = y2
So f(x) maps x1 into two different values, y1 and y2, then this is not a function.
Now, you want to change the point (1, 4) of a relationship in order to transform it into a function (so in the relation R we have two points with x = 1, and differet values of y). Then you need to choose the option that in the x-component does not have the same value that one of the other data points of the relation.
Answer:
Its called the common ratio.
Hope this helps!
