Given:
Cost of 1 digital song = $1.05
Cost of 2 digital song = $2.10
Cost of 5 digital song = $5.25
To find:
The equation and the cost of 25 downloaded digital songs.
Solution:
Let us take two points (1, 1.05) and (2, 2.10).
Here 
Slope:
m = 1.05
Using point-slope formula:
Add 1.05 on both sides, we get
Here x is the independent variable and c is the dependent variable.
So that substitute x = n and y = c.
The equation is c = 1.05 n.
Substitute n = 25 in the equation.
The cost of 25 songs is $26.25.
Y+x=6
y=x^2-6x+6
You would have to expand the second one.
y=x*x-6x+6
and you add all of the x's
y=-6x^3+6
y+x=6
Solve the one that's in y=mx+b form.
And you should be able to solve it from there.
Step-by-step explanation:
42:36:54 divide this by 6
= 7 : 6 : 9 simplest form
Answer:
(C)As x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞.
Step-by-step explanation:
Given the values in the table:
We observe from the table that:
As x increases, the value of f(x) decreases
- i.e. Over time, when x → ∞, f(x) → –∞
As x decrease, the value of f(x) increases
- Similarly, when x → –∞, f(x) → ∞.
Therefore: that which best predicts the end behavior of the graph of f(x) is:
(C)As x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞.
