From 2006 to 2010, the cost of a train ticket from Boston to New York could be modeled by C(y)=($73.00)(1.1)y−206 where y is the year and C(y) is the cost in a given year.

According to this model, in what year would the cost of a ticket have been $90?

answer: two five pound bags one two pound

step-by-step explanation:

what are the statements

step-by-step explanation:

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.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
