The manager of a local discount store reduces the regular retail price of a certain cell phone brand by $3.
a. Use y to represent the regular retail price and write an expression that represents the
discounted price of the cell phone.
b. If 4 of these phones are sold at the reduced price, write an expression in expanded form
(without parentheses) that represents the store's total receipts for the 4 phones.
a. Write an expression that represents the discounted price of the cell phone.
The expression is |
(Type an expression using y as the variable. Do not include the $ symbol in your answer.)

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.

$450 i think. hope this ☺
