The answer is 90 lightbulbs.
b(n) - the number of light bulbs
n - the number of chandeliers
The function is b(n) = 6n
If n = 15, then:
b(15) = 6 · 15 = 90
Therefore, the number if light bulbs needed for 15 chandeliers is 90.
It is the third one on the graph.
Answer:
I only know number 5 so here it is
the solution for the left is: 2x6=12
the solution for the right is: 5x3+4x1=15+4=19
and the answers are: 1.12 . 2.19
Exponents if those are the answer it bc the second number is an exponent
3^3= 27
4^3=64
3^4=81
Perpendicular lines have slopes that are negative reciprocals
so if m1 = -3
the perpendicular line has a slope of 1/3
