X=4
(X+20)/2 = 3x
Multiply everything by 2 to cancel out the 2; therefore, (x+20)= 6x
Now solve for x,
20= 6x-x
20= 5x
Divide everything by 5 to solve for x,
20\5 = 5x/5
4=x
So here you want to show all values greater than the parabola shown. The following parabola can be found by looking at the x intercepts. Here you have x=-3 and x=2. So your parabola can be defined as y=(x+3)(x-2) because when you make those two equal to zero you get x=-3 and x=2. And so then you go ahead and do the FOIL method for both of them when you multiply and you get
y=x²-2x+3x-6 which is
y=x²+x-6
Because the parabola is shaded above, it indicates that all the values greater than y are shaded and it’s with a solid line, therefore your answer for this inequality would be choice B. I hope this helps!!
Answer:
Step-by-step explanation:
Let's first understand what percentage of the population actually exists after the decrease.
<h3>100% - 35% = 65% of the population.</h3>
We'll now convert 65% into a decimal. We can convert percentages into decimals by dividing the percentage by 100.
<h3>0.65 / 100 of the population.</h3>
We'll now make an equation.
<h2>0.65x = 29,900</h2><h2>x = 46,000.</h2><h3>Keep in mind that x, in the equation, is to represent the previous population. When you multiply it by 0.65, you're representing 65% of x which is also equal to 29,900. When you multiply the equation by (100/65) on each side, you find out the previous population is 46,000.</h3><h2>If you have issues or difficulties, feel free to contact me.</h2>
Here is a simple way we can do this.
We have six blanks.
__ __ __ __ __ __
Now, we have 13 possible options to fill in blank number one.
13 __ __ __ __ __
Now we have 12 possible options to fill in blank number two because one person has already been chosen.
13 12 __ __ __ __
Now we have 11 possible options for blank number three.
13 12 11 __ __ __
Now we have 10 possible options for blank number four.
13 12 11 10 __ __
And so forth until we get:
13 12 11 10 9 8
Now we just have to multiply the numbers all together.
13 * 12 * 11 * 10 * 9 * 8
is equal to:
1235520 ways.
