9(-7b-6)
-63b-54
What I did was multiply 9 by -7b to gt -63b. Then, I multiplied 9 by -6 to get -54. :) hope this helps
The given functions are

Evaluate the functions.
1. Because 7/4 > 1 and the exponent is positive,
the function does not decay.
2.Because 4/5 < 1 and the exponent is negative,
the function does not decay.
3. Because 8/7 > 1 and the exponent is negative,
the function decays.
4. Because 9/2 > 1 and the exponent is positive,
the function does not decay.
A composite plot the functions verifies the answer.
Answer:
the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!
She will also need the minimum value, the median, the upper quartile and the lower quartile.
The box will be drawn from the upper quartile to the lower quartile, with a vertical line at the median. The whiskers will go from the box to the highest and lowest values.
