Point T' has coordinates (-3, 4). If it was translated up 3 units, what were the coordinates of its pre-image?

Translation refers to a rigid motion or transformation where you move an object from one location to another.
Translations are base on the rule (x,y) -- (x+a, y+b) where the words right and left represent the change in the x-axis, and the words up and down the change in the y-axis.

In this exercise it is asked you to find the coordinates of the preimage of point T', which has the coordinates (-3,4) and is the effect of a translation of 3 units up. As previous said, the words up and down represent a change on the y-axis, meaning that the y-coordinate is the one that should be changed.

If the translation from the preimage to the image was 3 units up, then the preimage can be found by subtracting three units.
Pre-image: (-3,4-3)= (-3,1)

The point that represents the coordinates of the pre-image is (-3,1).

A regular tube of toothpaste costs $2.50 for 3.2 ounces. A travel size tube costs $1.00 for 1.2 ounces. Compare the prices and w

Len [333]

Answer:

The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy

Step-by-step explanation:

step 1

<em>Find out the unit rate of a regular tube of toothpaste</em>

we know that

To find out the unit rate, divide the total cost by the total weight

$\frac{2.50}{3.2}=\$0.78\ per\ ounce$

step 2

<em>Find out the unit rate of a travel size tube of toothpaste</em>

we know that

To find out the unit rate, divide the total cost by the total weight

$\frac{1.00}{1.2}=\$0.83\ per\ ounce$

step 3

Find out the percent of increase

we have that

The unit rate $\$0.83\ per\ ounce$ represent the 100%

so by proportion

Find out what percentage represent the difference ($0.83-$0.78=$0.05 per ounce)

$\frac{0.83}{100\%}=\frac{0.05}{x}\\\\x=100(0.05)/0.83\\\\x=6\%$

therefore

The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy

Thepotemich [5.8K]

Given:

The volume of water in a tank is modeled by the function

$y=1.15x^3-0.1x^2+2$

where, x is the number of minutes after the faucet filling the tank is turned on.

To find:

The y-intercept and what does it represent in this context?

Solution:

We have,

$y=1.15x^3-0.1x^2+2$

Substituting x=0, we get

$y=1.15(0)^3-0.1(0)^2+2$

$y=0-0+2$

$y=2$

Therefore, the y-intercept is 2 and it represents the volume of water in a tank before the faucet filling the tank is turned on.
