|x| = -2
Because the absolute value of a number cannot be a negative number, this equation has no solution.
What you need to do is plug each x value into the equation to find out the corresponding y value.
for example, when x=-2, y=(-2)²+3(-2)+2=4-6+2=0
the outputs are 0, 0, 2, 6, 12
So, the population will always be 50 percent of the previous population counted.
4,500×1.50^x=y
4,500 is the population that it starts with, while 1.50 is telling that it is increasing by 50%. X is the number of years.
We are trying to find it in 88 years, so we should replace x with 4. Here is the reason, it doubles every 22 years and we are looking 88 years.
4,500×1.50^4= 22,781.25
There can't be .25 of a person, so the answer would be 22,781.
Hello
there is a base charge of 10 (+10)
and each ticket is multiplied by 0.25 (0.25t)
10+0.25t
hope this helped :)
