Answer:
'-5'
Step-by-step explanation:
The table is a linear function. This means that all the points have a consistent slope. If two points had a different slope, it would be a nonlinear function.
Slope is rise over run. We are given the points (-3,0) and (-2,-5).

Answer:
The cost of 7.5 lbs of chopped walnuts is $25.875
Step-by-step explanation:
we are given
It costs $3.45 to buy lb of chopped walnuts
so,
1 lb of chopped walnuts = $3.45
now, we can multiply both sides by 7.5
so, we get
7.5 lbs of chopped walnuts = $25.875
So, the cost of 7.5 lbs of chopped walnuts is $25.875
Answer:
a. y = 4,200
b. 9.2%
Step-by-step explanation:
Given the information:
=> the base number of the exponential function is:
100% - 2.4% = 97.6% = 0.976
Let t is quarter
Let y is the population
=> the following shows an exponential decay function to find the quarterly decay rate is:
y (t)= 4,200
b. The population is decreasing by how much percent per quarter?
Let t = 0 we have: y(0) = 4,200
Let t = 1 we have: y(1) = 4,200
=> the decreasing percentage is:
= (y(0) - y(1)) / y(0)*100%
= (4200 - 3811) / 4200 *100%
= 389/4200*100%
= 9.2%
