Mathematics

Answer:

We know that Amber decided to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, and after this, the function representing the photo shares is:

f(x) = 3*(4)^x + 45

We do not know the initial function, but with the given information we can assume that the original equation is:

g(x) = 3*(4)^x

Then the new function is:

f(x) = g(x) + 45.

This is a vertical translation, remember that for a function h(x), a vertical translation of N units is written as:

k(x) = h(x) + N

if N is positive, we have a translation of N units up

if N is negative, we have a translation of N units down.

in this case we have;

f(x) = g(x) + 45

This means that f(x) is a vertical translation of 45 units of g(x), then:

the graph of the new function is 45 units above the original function.

Find the best buy (based on price per unit) for cereal.
Salsk061 [2.6K]
Answer:

21-ounce size: $3.89

Explanation:

To compare the cost, you can calculate the cost per ounce of cereal. This means you will have to divide the cost by the total number of ounces. The cereal that costs the least per ounce will be the best buy.

$4.79 / 18oz = $0.27/oz

$3.89 / 21oz = $0.19/oz

$6.49 / 32oz = $0.20/oz

The 21-ounce size is has the cheapest price per ounce, so this is your best buy.

Find the values of x and y​
valentina_108 [34]

Answer:

x = 3, y = 1

Step-by-step explanation:

2 raised to what power gives you 16?

2*2*2*2 = 16 so 2^4

3 raised to what power gives you 9?

3*3 = 9 so 3^2

the exponent cannot be negative so x has to be greater than y and x cannot be the same as y otherwise you will get a 0.

x = 3 , y = 1

2^(3+1) = 2^4 = 16

3^(3-1) = 3^2 = 9

-2w + 20= -17 -17 +4w
mixas84 [53]

-2w + 20 = -17 - 17 + 4w

Combine like terms on the right side of the equation.

-2w + 20 = -34 + 4w

Add 2w to both sides.

20 = -34 + 6w

Add 34 to both sides.

54 = 6w

Divide both sides by 6.

w = 9 is your answer.
