Essie owns a hot dog stand and sells specialized hot dogs. he charges $1.50 for a plain hot dog and then an additional $0.50 for each topping that you want. this can be modeled by the equation c = .5x + 1.5, where c is the total cost of the hot dog and x is the number of toppings you ordered. the company that he buys his hot dogs from was having a sale so he was able to buy the hot dogs for less. he will now sell them for $0.25 less than before. what should be changed in the equation c = .5x + 1.5 to represent this?

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
