Answer:
Step-by-step explanation:
<u>"The product"</u> means multiplication so we have to multiply these two values together.
When we multiply two negative numbers together <u>it results in a positive</u>.
Keeping this in mind, solve the equation.
-3 1/4*-1 1/2
First multiply the fractions
1*1=1
4*2=8
1/8
Now the numbers.
-3*-1=3
The answer is 3 1/8.
Hope this helps!
sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Answer:
Town B will eventually overtake Town A
in 1990 Town B will have a larger population
Step-by-step explanation:
To work out how big town A will be in 1990 you need to do 200 + (200x40) because you add 40 years worth of increased population onto the starting population
To work out how big town B will be in 1990 you need to use the equation 200 X 1.1^40 because to work out plus 10 percent you need to do 1.1 and do it to the power of 40 for how many years
in 1990 town a will have a population of 8200 and town B will have a population of 9051.85
