The letter 'C' has 2 lines of symmerty
the upper-case 'D' has 2 lines of symmetry
the uper -case 'E' has 2 lines of symmetry
the upper case 'H' has 2 lines of symmetry
the upper case 'I' has 2 lines of symmetry
the small case 'L' has 2 lines of symmmetry
the letter 'O' has infinite lines of symetry
the letter 'x' has 4 lines of symmetry
recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.
Answer:
Step-by-step explanation:
Let x represents the amount that the customer pays per hour
for renting the vacuum cleaner before returning it.
Let y represent the flat rate that the store charges a customer for renting the vacuum cleaner.
Let F represent the amount that the store charges a customer for renting the vacuum cleaner for x hours.
A linear function F for the total retail cost of a vacuum cleaner would be
F(x) = x + y
If the customer rents it for n hours, the total amount becomes
F(x) = nx + y
Graphing it @ https://www.desmos.com/calculator , we get that f(x) clearly approaches inf at x=10 and a vertical asymptote is clearly 10
