I believe it's the second answer, where "the test contains 10 3-point questions and 14 5-point questions."
Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
<em>we translate word problem to equation.</em>
<em />
<em>8219.5 IS 85% of TOTAL</em>
<em />
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
<em>8219.5 = 0.85 * Total</em>
<em>Hence, total = [let total be 7]</em>
<em>8219.5 = 0.85 * t</em>
<em>t = 8219.5/0.85 = </em><em>9670 feet</em>
An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....
y=x+5 subtract 5 from both sides
y-5=x now switch labels
y=x-5
So if f(x)=x+5
f^-1(x)=x-5
