What index of m will be 1/m​
Mashcka [7]

Answer:

-1.

Step-by-step explanation:

1/m = m^-1.

We can show this is correct if we simplify the following:

m^2 / m ^3  =  m * m / m * m* m = 1/m

By the law of indices: m ^2 / m^3 = m^(2-3) = m^-1.

If x² - y² = 55, and x - y = 11, then y =<br> a. 8<br> b. 5<br> c. 3<br> d. -8<br> e. -3
irina1246 [14]
X^2-y^2=55
this means that 
(x+y)(x-y)=55
we know that x-y=11 so we can write
(x+y)(11)=55
x+y=55/11 we divide by 11 and we obtain 
x+y=5

x-y=11 this means
x=y+11 we replace in the other equation (x+y=5)

y+11+y=5
2y=5-11
2y=-6
y=-3
and you find out that also 
x=8

If a city with a population of 50,000 doubles in size every 16 years, what will the population be 32 years from now?
Oksanka [162]
Pretty sure its 200,000 because, 16 goes into 32 twice and its doubles 50,000 every 16 years, so it would be 50,000 multiplied by 4 since it doubles . and that would give you 200,000. (it was hard explaining this)
