In 2004, there were approximately 275 students in the Delaware High School band. In 2010, that number increased to 305. Find the annual rate of change in the number of students in the band.
Answers
Since there is a difference of 6 yaers between 2010 and 2004, you devide 30 by 6 which equals to five. Therefore each year there was an increase of 5 students in the band.

Answer:
s = 2
Step-by-step explanation:
6s - 4 = 8
Additive inverse of (-4) is 4. So, add 4 to both the sides
6s - 4 + 4 = 8 + 4
6s = 12
Now divide both the sides by 6.
s = 2

Martin’s Gift Card
Days
2 4 5 7
Amount remaining 24.10 18.20 15.25 9.35
A.
y – 9.35 = −2.95(x – 7)
B.
y – 18.20 = 2.95(x + 4)
C.
y + 15.25 = −2.95(x + 5)
D.
y + 24.10 = 2.95(x – 2)
Answers
We want to see which linear equation represents the amount remaining on the gift card. We will see that the correct option is A:
y – 9.35 = −2.95(x – 7)
A linear equation in the point-slope form is written as:
y - y₁ = a*(x - x₁)
Where a is the slope of the line and (x₁, y₁) is a point on the line.
If we know two points on the line, (x₁, y₁) and (x₂, y₂) then we can write the slope as:
Here we can use the two first points:
(2, 24.10)
(4, 18.20)
Then the slope is:
Then the equation is something like:
y - y₁ = -2.95*(x - x₁)
Now, from the given options the only one where (x₁, y₁) is a point on the line is the first option, where:
x₁ = 7
y₁ = 9.35
So the correct option is A:
y – 9.35 = −2.95*(x – 7)
