Answer:
No it isn't a function
Step-by-step explanation:
It is not a function because the X-value -1 is assigned to two different numerical Y-values/ outputs
Answer:
The linear model of her monthly earnings is; Y =1200 +0.03*X. The amount earned is 1350; choice A
Step-by-step explanation:
Let Y denote her monthly earnings and X her total sales. The linear model can thus be formulated as; Y =1200 +0.03*X. We are then to find the value of Y given X =5000. We simply substitute X =5000 into the linear model which yields; Y =1350

Answer: 17 years
Step-by-step explanation:
City A is currently 2,425 people in number and growing at 27 per year.
An expression to find the population in a given year assuming the year is x would be:
= 2,425 + 27 * x
= 2,425 + 27x
Applying the same logic to City B would give an expression of:
= 1,813 + 63x
Equating these together will give the year they will be the same:
2,425 + 27x = 1,813 + 63x
2,425 - 1,813 = 63x - 27x
612 = 36x
x = 612/36
x = 17 years
The value of x is more 90 because the angle is an obtuse and an obtuse is more than 90 degrees.
