Answer:
Step-by-step explanation:
Take the negative exponent in the denominator to make it positive
Example = (2^-3)
= 1/2³
Answer:
(-1,-6)
Step-by-step explanation:
Plug 6x for y into the bottom equation:
2x+3(6x)= -20
2x+18x= -20
20= -20
x= -1
Substitute -1 for x in the equation for y:
y=6(-1)
y=-6
I hope I could help :)
Answer:
Scatter plot
Step-by-step explanation:
Using a scatter plot will allow the sales manager to show the data collected about the number of customers who enter the store and the dollar volume of sales for each day because the plot will have a dot to represent each day. The analyze of the pattern formed by the dots will show if there is a relation between the variables and what kind of relation is (systematic or causal). She can also add a regression line to find an explanation for the relation between the variables.
Given:
Current population = x
The population of a city is expected to decrease by 6% next year.
To find:
The expression that represents the expected population next year.
Solution:
We have,
Current population = x
Decrease rate = 6%.
Expected population next year = Current population - 6% of Current population
=
=
=
Therefore, the expression for the expected population next year is 0.94x.
If we are only using the values in the table, then the answer is D.
This is because the highest value of y is 40 and the lowest is 37.75. So we must know that y is between these two.
However, if we are using this table as a long term model, then C is the correct answer. We know there is 40 to start and it will continue going down until it hits 0.
