Answer:
- 3/x-1
Step-by-step explanation:
E^2x -2e^x -8=0 => e<span>^(2x) -2e^x -8=0
Temporarily replace e^x with y.
Then (y)^2 - 2y - 8 = 0. Factors are (y-4) and (y+2).
Roots are y = 4 and y= -2.
Now remembering that we temporarily replaced e^x with y, we let
y=4 = e^x. We need to solve for x. Taking the natural log of both sides, we get:
ln 4 = x (answer)
We have to discard the other root (y= -2), because we cannot take the ln of a negative number.

Answer:
y=mx+b
Step-by-step explanation:
b is wherever the line intersects the y axis.
m is the slope, rise/run. hope this helps! please mark brainliest!
3 feet= 1 yard
16*3= 48 feet.
47.52/48= 0.99
It will cost Brian $0.99 per foot.
Find the unit rate.
49.50/50= 0.99
No, it wouldn't. It would be the <em>same price
0.99=0.99 It doesn't matter which one Brian chose. </em>
I hope this helps!

PQS = 40 because if you look at the image above it half equals 20 and 20+20=40
