<u>Answer:</u>
<u>
</u>
<u>Step-by-step explanation:</u>
To solve a complex fraction like 
, take LCM of both the terms separately first to get:
= 
and
Now combine and divide these terms to get:
The term 
in both the denominators will be cancelled out by each other and you will be left with:
Therefore, the expression is equivalent to the given complex fraction.
Since the lines are parallel, you know that they have the same slope, which is 2. If you look at the coordinate grid you can see that line y_{2} crosses the y-axis at (0, 1), making the y-intercept 1. Now that you know the slope is 2 and the y-intercept is 1, you can piece those into a slope-intercept equation.
y = mx + b where m is the slope and b is the y-intercept
y_{2} = 2x + 1
Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day
