This question is unclear, I don't understand and it doesn't ask the question.
Y=-2+y/2 you have to subtract 4 from both sides y from both sides.
The formula for exponential growth is y=a(1+r)
. Where a is the initial value when time is 0 (100 in this case). r is the growth rate, we can see that the growth is 10%. And x is how much time has passed, we want to find out how many trucks after 9 years.
So we would plug the values in to get y=100(1+.1)
. Solving this gives us 235.79, so we would round up to 236, and our answer would be 236 trucks registered in the city in year 9.
Edit: The x and the 9 are exponents, the formatting made them look a bit weird.
Answer:9x+6
Step-by-step explanation:
If I understand the question correctly, you add 2x and 7x which equals 9x and then 1+5 equals. Which is the simplified answer. Sorry if I didnt understand the question correctly.
Answer:
8 times
Step-by-step explanation:
we have a 1/3 chance per spin to land on red
so we would expect it to land 33.3% of the time
1/3*24=8
another easy way is to divide by 3
24/3=8
