-7.
5x-3 = -15
-15-4\4= -16
-16 + 9 = -7
The player took a total of 70 shots and missed about 28 shots.

Percentage</h3>
Percentage is used in expressing a fraction number or decimal in fraction of 100. It is expressed using the '%' sign.
Given a total shot of 100, since the player took 70% of the shot, hence:
Total shot taken by the player = 70% of 100 = 0.7 * 100 = 70 shots.
Total shot shot missed = (100% - 60%) of 70 = 40% of 70 = 0.4 * 70 = 28 shots.
The player took a total of 70 shots and missed about 28 shots.

I can't see how any of those formulas show exponential decay. (Did you type those correctly?)
The formula that will show the remaining amount correctly is:
ending amount = Bgng Amount / 2^n
where "n" is the number of haf-lives.
So, for example if half life = 4 hours and if we want to calculate the amount after 9 hours (that's 2.25 half-lives) then:
ending amount = Bgng Amount / 2^n
ending amount = 50 / (2^(9/4))
ending amount = 50 / 2^2.25
ending amount =
50 / <span><span><span>4.75682846

Answer:
20 hours
Step-by-step explanation:
use this linear equation
y = 9.25x + 50
plug in 235 for y and solve for x
235 = 9.25x + 50
185 = 9.25x
20 = x
so he worked for 20 hours
hope this helped <3
You cannot factor it, so there is no simplification. The Constants "4" and "9" do not share a common factor, therefore, you cannot simplify it. However, if it was a number such as "8" replacing "9", then you can simplify by doing:
4(x^2 - 2) = 4x^2-9
