Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5
The given function is:
f(x) = ax - 5
If f(4) = 15, then x = 4
Substitute x = 4 into f(x) = ax - 5
f(4) = a(4) - 5
15 = 4a - 5
Solve for a by adding 5 to both sides
15 + 5 = 4a - 5 + 5
20 = 4a
Divide both sides by 4
4a/4 = 20/4
a = 5
Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5

Answer:
A
Step-by-step explanation:
pythagorean theorem
A^2+B^2=C^2 do that for all sides then add
First you would subtract x from both sides to move all the x's to one side
Then you would add 4 to both side to move all the non x's to one side
Lastly divide by negative 15 to have x by itself
9/-15 =-.6
So x as has root at x=-0.6
Youre missing a graph, but luckily I figured it out.
B Is correct.
C is correct. Domain: (−∞,∞)
Population density = population/area
Califonia = 36,500,000 / 163,707 = 223.0 persons per square mile
Florida = 18,300,000 / 65,758 = 278.3 persons per square mile
Iowa = 2,990,000 / 56,276 = 53.1 persons per square mile
New Jersey = 8,690,000 / 8,722 = 996.3 persons per square mile
Wyoming = 522,000 / 97,818 = 5.3 persons per square mile
