A set of equations is given below:
1 answer:
Answer:
D.
Step-by-step explanation:
Equation A: v = 4v + 5
Equation B: v = 3v + 5
---------------------------------
4v + 1 = 3v + 5
-3v
---------------------------------
v + 1 = 5
-1 -1
---------------------------------
v = 4
---------------------------------
v = 4(4) + 1 = 17
v = 3(4) + 5 = 17
Thus, your answer is D. 4v + 1 = 3v + 5.

Hoi!
To solve this, first plug in the values for x and y.
x = 2, so anywhere you see x, put 2 in its place.
y = 3, so anywhere you see y, put 3 in its place.
4 × 2 = 8
× 3 = 
= 
is your answer.

Answer:
Step-by-step explanation:
We are looking for what number times .50 makes the equation true.
So, just do backwards equation:
Thus, meaning that what multiplied by 0.50 is equal to 17?
[tex]0.50 * 34[tex]
[tex]==> 17[tex]
It would take about 57 hours for the number of spores to be less than 500 spores.
<h3>Exponential Function</h3>An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y is the number of pores after x hours.
a = 6200, b = 100% - 20% = 0.8, hence to be less than 500 spores:
(x/5) * ln(0.8) < ln(0.08)
x > 56.4 hours
It would take about 57 hours for the number of spores to be less than 500 spores.
