Answer:b
Step-by-step explanation:
(×+1)(×-1)
---------------
(×+1)(×+7)
=cancel (×+1) both the numerator and denominator then you are left with
(×-1)
-------
(×+7)
=(×-1)/(×+7)
Answer:
the slope-intercept equation of a line that passes through the coordinate (-4,5) and (8,-1) is
Step-by-step explanation:
1) Apply the slope formula; y^2 - y^1 divided by x^2 - x^1
y^2 is -1
y^1 is 5
x^2 is 8
x^1 is -4
-1 - 5 = -6
8 - (-4) = 12
-6/12 is -1/2 or -0.5
2) To find the y-intercept, hoose either of the coordinates and replace y, m, and x in the y= mx+b formula.
5= -0.5(-4) + b
5= 2 + b
3= b
Answer:
<u>The equation would be:</u>
<u>p = 10,000 * (1 + 0.2)∧ t</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Current population of a town = 10,000 inhabitants
Growth rate of the population = 20% annually
2. Which equation could be used to find the population after T years?
p = Population of the town after t years
t = Number of years
We will use the following equation:
<u>p = 10,000 * (1 + 0.2)∧ t</u>
For example, let's calculate the population after 6 years, replacing with the real values, we have:
p = 10,000 * (1 + 0.2)⁶
p = 10,000 * 2.986
p = 29,860 inhabitants
