Slope is rise over run or (y₁-y₂)/(x₁-x₂)
(x,y)
(1,3)
(3,-2)
(3-(-2))/(1-3)=(3+2)/(1-3)=5/-2
slope is -5/2
Answer:
Step-by-step explanation:
apply the inverse properties of logarithmic and exponential functions to simplify
all logs has base 'e'
Inverse property of log says that
, the value of ln e=1
we apply this property in our problem. ln has same base 'e' . ln and 'e' gets cancelled
<u>Answer-</u>
2, 4, and 8 people will need 1, 2, 4 pounds of turkey respectively.
<u>Solution-</u>
Given in the question, number of pounds of turkey varies directly with the number of people, i.e as the number of people increases or decreases, the pound of turkey also increases or decreases.
Taking,
x = number of people,
y = pounds of turkey.
This condition can be represented as,
As given in the question, when x = 6 y = 3
Now, putting the values of k in the equation, the equation becomes
Now, we can get the values of y or number of pounds of turkey needed by putting the given x or number of people.
All the calculations are shown in the attached table.
Given points (9,5) = (x1, y1) & (9, -3) = (x2 , y2)
Slope = y2 -y1/ x2 - x1
= -3-5 /9-9
= -8/ 0
As the denominator is zero the slope is ND (not defined)
