What is the equation for the translation of x2 + y2 = 9 four units to the right and three units down?

1 answer:

3 0

Assuming the equation reads:

$x^2 + y^2 = 9$

To move the equation to the left or right, you will either add or subtract a value from x. Adding a value to x will move it to the left, and subtracting a value will move it to the right.

To move the equation up or down, you will either subtract or add a value to y. Subtracting a value from y will move it up, and adding a value will move it down.

The translation is 4 units right, and 3 units down. Movement to the right means that we'll subtract from x, and movement down means that we'll add to y. The following equation will represent the translation, and is your answer:

$\boxed{(x-4)^2 + (y+3)^2 = 9}$

Lia is cooking.She needs 2 3/4 cups of flour and 4 3/4 cups of cornmeal.Lia wants to bake sure she has a bowl big enough to hold

Sholpan [36]

Answer:

Lia needs $7\frac{2}{4}\ cups$ of flour and corn meal.

Step-by-step explanation:

Given:

Amount of flour needed = $2\frac{3}{4} \ cups$

$2\frac{3}{4} \ cups$ can be Rewritten as $\frac{11}{4}\ cups$

Amount of flour needed = $\frac{11}{4}\ cups$

Amount of Corn meal needed = $4\frac{3}{4}\ cups$

$4\frac{3}{4}\ cups$ can be Rewritten as $\frac{19}{4}\ cups$

Amount of Corn meal needed = $\frac{19}{4}\ cups$

We need to find the total amount of of flour and cornmeal she needs.

Solution:

Now we can say that;

the total amount of of flour and cornmeal she needs is equal to sum of Amount of flour needed and Amount of Corn meal needed.

framing in equation form we get;

the total amount of of flour and cornmeal she needs = $\frac{11}{4}+\frac{19}{4}=\frac{11+19}{4}=\frac{30}{4}\ cups\ \ OR\ \ 7\frac{2}{4}\ cups$

Since Answers are not given:

Kindly chose the answer which contains below data.

Hence Lia needs $7\frac{2}{4}\ cups$ of flour and corn meal.

Which of the following is NOT TRUE about the distribution for averages?

Galina-37 [17]

Answer:

The following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed(that is, skewed to the right).

Step-by-step explanation:

In a normal distribution the properties of which are given as follows:

i) all the central tendency measures, that is, the mean, the median and the mode are equal.

ii) The area under the bell curve is equal to one.

iii.) The bell curve is symmetric about the center, or mean.

iv.) The bell curve does not touch the x - axis.

Therefore only the following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed (that is, skewed to the right).

When you add two rational numbers, each number can be written as a?

ra1l [238]

The correct answer to your question is... a rational #, because when you add two rational #'s, each # can be written as a rational #.

Reasoning:
So, adding two rational #'s like adding fractions will result in another fraction of this same form since integers are closed under + and x. Thus, adding two rational #'s produces another rational #.

By the way # means number.

I hope this helps!
