PLEASE HELP THANK YOU
Svetllana [295]

Answer:

change in the total cost for each book printed = $15

cost to get started (before books are bought) = $1200

Step-by-step explanation:

IF the eqn is y = 15x +1200

where y  represent the total cost of publishing a book (in dollars) and

x  represent the number of copies of the book printed


then cost to get started (before books are bought) can be found by substitute x=0 into the eqn

y = 1200 + 15*0 = $1200


change in the total cost for each book printed will be the difference in total cost at x=0 and x=1

when x=0, y=1200

when x=1, y=1200+15*1=1215

so the change in total cost=$15

Which choices are equivalent to the exponential expression below? check all that apply. (2/3)^3
rosijanka [135]

Answer:

B. (2/3) x (2/3) x (2/3)

C. 8/27

D. 2^3 /3^3

Step-by-step explanation:

You need to know the following property

\LARGE \left(\frac{a}{b} \right)^c = \frac{a^c}{b^c}

Exponent also means you're multiplying the same number for an 'n' number of times.

For example, 2^3 = 2 * 2 * 2

we multiply it by itself 3 times since 3 is the exponent.

x^y

x is the base, y is the exponent

we read it as x to the power of y

If the exponent is 2, we say it as x squared

If the exponent is 3, we say it as x cubed
