Answer:
a) 0.4
b) 0.07
c) 3
e) 1.23
f) 0.19
I) 3.3 = 3.300
j) 5.64
Step-by-step explanation:
0.4 = 4/10
0.07 = 7/100
0.603 = 603/1000
0.64 = 0.64000000
In the situation, the number of bacterias are doubling for each sheet of paper cut, thus, the exponential equation for the puber is:
Initially, there was only one sheet of paper. Then, each sheet is cut in half, so we will have 2 sheets, then 4 sheets, then 8 sheets, and so on. That is, the number of sheets is continuously doubling, thus, the population after n cuts can be modeled by the following <u>exponential equation</u>:

Answer:
x = -2
y = -4
Step-by-step explanation:
The way systems of equations work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*
so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.
that would leave
5x = -10
divide both sides by 5
x = -2
Now that we know x = -2, we can plug in -2 into one of the equations to find y.
2 ( -2) + 5y = -24
-4 + 5y = -24
-4 + 4 + 5y = -24 + 4
5y = -20
y = -4
x = -2
y = -4
