<h3>
Answer: D) h(x) = (1/4)x</h3>
This is the same as h(x) = x/4
In decimal form, it would be h(x) = 0.25x
=============================================
Explanation:
Inverses undo the original function. The original function tells us to take any input (x) and multiply by 4 to get the output y = f(x) = 4x
To get the inverse, we reverse the operation applied here. The opposite of multiplication is division. So we'll divide by 4 instead of multiply by 4. This is why the answer is x/4 or (1/4)x
-----------
Another approach is to do the following: Replace f(x) with y. Swap x and y. Solve for y
f(x) = 4x
y = 4x
x = 4y
4y = x
y = x/4
h(x) = x/4
We end up with the same result as before.
-----------
Extra info:
For any real number x, the following two equations are true
h( f(x) ) = x
f( h(x) ) = x
Im mot sure of the answer
Answer:
3p - 19
Step-by-step explanation:
8 + 3(p - 9)
Distribute;
8 + 3p - 27
Collect like terms;
-19 + 3p
The table of the relative frequencies show that <u>70% of 8th graders</u> want the water slides.
There is an association between grade level and field trip choice with the higher grades preferring Water slides more than roller skating.
9th graders would prefer waterslides if the trend continues.
<h3>What does the frequency table show?</h3>
The percentage of 8th graders who want to go to water slides is:
= 0.14 / 0.20 x 100%
= 70%
As the grades increase, less people want to go roller skating which means that should this trend continue, 9th graders would prefer water slides.
