Answer:
-6 and -10
Step-by-step explanation:
Three times negative two equal to negative six
Negative two plus negative eight equal to negative ten
Answer:
In 2003, the population was 59000 and the population has been growing by 1,700 people each year.
A.
The equation will be:
59000+1700x = (population 'x' years after 2003)
For x, you plug in the amount of years after 2003.
Like if it is the year 2003, the population is
= 59000
when it is year 2005, the population is
= 62400
B.
The town's population in 2007 will be :
Population = 65800
C.
=>
x = 11
Means
Hence, by year 2014 the population will be 77700.
The answer is c 19
38/2=19
Step-by-step explanation
Answer:
Step-by-step explanation:
13.84%,0.84
14.10,12,12,14,15,17,20.Median is 14.Mode is 12.
15.Mean so add 18+19+20=57.57/3 =19.
Answer:
Vertex: (4, -2)
Vertex form:
Inverse function:
Step-by-step explanation:
The x-coordinate of the vertex can be calculated using the formula:
Where a and b are coefficients of the quadratic equation in the form:
So, using a = 2 and b = -16, we have:
To find the y-coordinate of the vertex, we calculate y using the x-coordinate of the vertex:
So the vertex is (4, -2)
The vertex form is given by:
Where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex. Therefore, we have that:
To create an inverse function, we switch x by y and vice-versa:
Then, using Bhaskara's formula, we have:
It's important to say that this inverse function is not really a function, because one value of x gives two values of y.
