Which type of transformation is shown?

Answer:

7 weeks, £35, and £21.

Step-by-step explanation:

Every week, Suzie saves £5 and gets £3 from her Mum. Altogether, Suzie gets £8 every week. All we need to do is divide 56 by 8, which gives us 7. Suzie will take 7 weeks to collect enough money. To find out how much she has saved and been given by her mum individually, we need only times these values by 7. 5x7=35, and 3x7=21.

Hello! The correct answer is 1,052.79.

You may remember the rounding rule..0-4 goes down, 5-9 goes up..

✨ You underline the "8" in "1,052.785". ✨

We can see, the number behind it is "5", which means 8 goes up once.

**ONLY** the 8 goes up, everything stays.

⌨ Which makes it 1,052.79! ⌨

Therefore, your answer is 1,052.79, I hope this helps you.

What is Algebraic expression ?

An algebraic expression is a mathematical expression that contains one or more variables, as well as numbers and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. It represents a mathematical relationship or rule and can be used to describe or represent quantities that can vary.

The equations that are true for x = -2 and x = 2 are:

\(x^{2}\)  – 4 = 0

This equation becomes (-2)2 - 4 = 0, which simplifies to 4 - 4 = 0, and it is true.

4 \(x^{2}\)  = 16

This equation becomes 4(-2)2 = 16, which simplifies to 4(4) = 16, and it is also true.

So, the correct options are:

\(x^{2}\)  – 4 = 0

4 \(x^{2}\)  = 16

Note: The other options are not true for x = -2 and x = 2. For example, x2 = -4 is not true for real numbers since the square of a real number cannot be negative. 3x2 + 12 = 0 is not true for x = -2 and x = 2, as it becomes 3(-2)2 + 12 = 0 which simplifies to 12 + 12 = 0, which is false. And 2(x - 2)2 = 0 is not true for x = 2, as it becomes 2(2 - 2)2 = 0, which simplifies to 0 = 0, and it is true, but it is not true for x = -2.

So, the correct options are  \(x^{2}\)  – 4 = 0 and 4 \(x^{2}\)  = 16.

The answer to the expression is  (x+3)/(x-1)

You should recall that a quadratic expression is an algebraic expression of the form ax2 + bx + c = 0, where a ≠ 0

The given expressions are

(x² - 3x - 18) / (x²- 7x +6

(x²-6x +3x +19) / (x²-x -6x +6)

This implies that {(x²-6x)+(3x-18)} / {(x²-x) -(6x+6)}

⇒[x(x-6)+3(x-6)] / [x(x-1) - 6(x-1)]

This means that [(x+3)(x-6)] / [(x-6)(x-1)]

Dividing by (x-6) to have

The average U.S. citizen uses approximately 88 gallons of water a day.

What is Frequency?

Frequency is a measure of how often an event occurs within a given period of time. It is typically expressed as the number of occurrences of a given event per unit of time. Frequency can be used to measure a variety of phenomena such as the frequency of sound in a given environment or the frequency of a particular chemical element in a given sample.

Selina's low-flow toilet and showerhead will reduce her total water use to just 48.4 gallons per day, a savings of 39.6 gallons of water each day. This is a 44.8% reduction in her water consumption, saving her almost 40 gallons of water per day.

By making these improvements, Selina is helping to conserve a precious resource and limit her environmental impact. Not only is she helping to conserve water, but she is also saving money on her water bill. It is estimated that a typical household can expect to save about $170 annually by making these simple changes.

In addition to her low-flow fixtures, Selina can take additional steps to reduce her water consumption. She can install a water-efficient dishwasher, reduce the frequency of her laundry loads, and install a rain barrel to collect rainwater for gardening. By making these changes, she can reduce her water consumption even further and save even more money.

The percent error in his calculation is 13.04%

He calculated the object will take 2.3 seconds to fall on the ground.

It takes 2.5 seconds for the object to fall.

Therefore, the percent error can be calculated as follows:

percent error = | theoretical value - experimental value | / theoretical value × 100

Therefore,

percent error = |2.3 - 2.5| / 2.3 × 100

percent error =  0.3 / 2.3 × 100

percent error = 0.3 × 100 / 2.3

percent error = 30 / 2.3

percent error = 13.0434782609

The J curve impact is an financial wonder that happens when domestic currency  increases in value in esteem relative to other monetary forms within the remote trade advertise. The J curve impact is named for the shape of the bend that's made when the adjust of exchange and the esteem of a country's currency are plotted against time.

Within the brief run, when a country's money increases in value, its sends out ended up more costly and imports ended up cheaper. This implies that the request for a country's sends out will diminish, whereas the request for imports will increase. As a result, the adjust of exchange will at first

compound, which implies that the nation will have a exchange shortfall.

Be that as it may, within the long run, the J curve impact predicts that the adjust of exchange will in the long run progress, and the exchange shortage will turn into a exchange overflow. This happens because the increment within the cost of sends out due to the appreciation of the currency will in the long run lead to a diminish within the amount of trades requested. At the same time, the diminish within the price of imports due to the appreciation of the money will in the long run lead to an increment within the amount of imports requested. Over time, these changes in request will cause a move within the adjust of exchange, coming about in a exchange excess.

In this manner, the Jcurve impact portrays the short-term weakening within the adjust of exchange that happens when a money increases in value, taken after by a long-term enhancement within the adjust of exchange. This impact is named after the shape of the bend that's shaped when the adjust of exchange and the esteem of a country's cash are plotted against time, which looks like a "J" shape.

The linear equation best estimate of the difference between the number of yellow and blue paper clips is option(b).

A linear equation is one that has the form y=mx+b in algebra. B is the slope, and m is the y-intercept. It's usual to refer to the previous clause as a "linear equation with two variables" because y and x are variables.

Number of yellow paper clips found in one box = 27955

Number of blue paper clips found in another box = 9427

We are asked to find the best estimate of the difference in the number of yellow and blue paper clips that Kimberly found.

The actual difference between the number of yellow and blue paper clips = 27955 - 9427 = 18528

An estimate of a number means the closest number that the actual number can be rounded off for simplifying calculations or understanding.

In this case, from the given options the closest number of 18528 is 19000.

Therefore option(b) is the best estimate of the difference between yellow and blue paper clips.

The system of equations is.

\(\begin{cases}\text{x}+\text{y}=60 \\15\text{x}+10\text{y}=800 \end{cases}\)

And the solutions are y = 50 and x = 10.

Let's define the two variables:

With the given information we can write two equations, then the system will be:

\(\begin{cases}\text{x}+\text{y}=60 \\15\text{x}+10\text{y}=800 \end{cases}\)

Now let's solve it.

We can isolate x on the first  to get:

\(\text{x} = 60 - \text{y}\)

Replace that in the other equation to get:

\(15\times(60 - \text{y}) + 10\text{y} = 800\)

\(-2\bold{y} = 900 - 800\)

\(-2\bold{y} = 100\)

\(\text{y} = \dfrac{100}{-2} = \bold{50}\)

Then \(\bold{x=10}\).

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.
