A store charges $2.10 for a medium bag of fruit slices. Assuming that the rate stays the same, how much should the store charge
melomori [17]
Hey there,

Your question states: <span>A store charges $2.10 for a medium bag of fruit slices. Assuming that the rate stays the same, how much should the store charge for a large bag of the slices?

So sense this is a medium bad of fruit slices, we would divide 2.10 by 2.

Your answer would be 1.5 Now, all we do is we add 2.10+1.5 and we get 3.15. The reason would be because sense we now know the price of the size of it being small, we just add that size on top of the medium size to get 3.15.

Hope this helps.

Which statement is true regarding the functions on the
Leto [7]

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Remember points on the graph get their location from the x-axis (horizontal) and y-axis (vertical).

In function notation, "f(x)" means when "x" is the value in the brackets, what the value of "y" will be.

First option for example: f(-3) = g(4)

<em>Value of "y" for f(x) when x = -3:</em>

On the blue line, when x = -3, y = -4.

<em>Value of "y" for g(x) when x = 4:</em>

On the red line, when x = 4, y = -3.

<u>Therefore</u>:

f(-3) = g(4)

-4 = -3          <= This is false.

In the third option: f(-3) = g(-3)

<em>On f(x) blue, when x = -3: </em>y = -4

<em>On g(x) red, when x = -3: </em>y = -4

<u>Therefore</u>:

f(-3) = g(-3)

-4 = -4                <= This is true.
