Using a system of equations, it is found that the charges of each item are given as follows:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

She brought 3 shirts and 1 pair of slacks and paid ​$12.36, hence:

3x + y = 12.36.

y = 12.36 - 3x.

She brought 5 ​shirts, 4 pairs of​ slacks, and 1 sports coat and paid ​$38.90, hence:

5x + 4y + z = 38.90.

z = 38.90 - 5x - 4y.

z = 38.90 - 5x - 4(12.36 - 3x).

z = 7x - 10.54.

She brought 5 shirts and 1 sports coat and paid ​$18.94, hence:

5x + z = 18.94.

Since z = 7x - 10.54:

5x + 7x - 10.54 = 18.94.

12x = 29.48.

x = 29.48/12

x = $2.46.

y = 12.36 - 3x = 12.36 - 3(2.46) = $4.98.

z = 7x - 10.54 = 7(2.46) - 10.54 = $6.68.

Answer: B and C

Step-by-step explanation:

When listing all the pairs of factors for a particular term, the factorization process is used.

This process is fundamental in number theory and is used to break down composite numbers into their simplest building blocks: prime numbers.

For example, if we want to find all pairs of factors for the number 24, we could follow these steps:

Start with 1 and the number itself (in this case 24), as these are always factors.

Check if 2 divides 24 evenly. If it does, then 2 and 24/2 (which is 12) are a pair of factors.

Continue this process with increasing numbers. Check 3 (yes, it works, with the pair being 3 and 8), 4 (yes, with the pair being 4 and 6), and so on.

When the numbers you're testing exceed the square root of the original number (approximately 4.9 for 24), you can stop, as you'll have found all pairs.

Answer:

\(f(x)=-3x^2+5\)

\(f(2) = -7\)

Step-by-step explanation:

Given equation:

\(y+3x^2=5\)

To solve the equation for y in terms of x, simply subtract 3x² from both sides of the equation:

\(\implies y+3x^2-3x^2=5-3x^2\)

\(\implies y=-3x^2+5\)

Replace y with the function notation f(x):

\(f(x)=-3x^2+5\)

Finally, to find the value of f(2), substitute x = 2 into the function:

\(\begin{aligned}\implies f(2)&=-3(2)^2+5\\&=-3(4)+5\\&=-12+5\\&=-7\end{aligned}\)

Answer:

Step-by-step explanation:

To find:-

Answer:-

We are here a given a equation, with some steps to follow, in order to find out the value of \(f(2)\).

Step 1 :- Solve the equation in terms of y ,

The given equation to us is,

\(\longrightarrow y + 3x^2 = 5\\\)

To solve for y , we need to transpose 3x² from LHS to RHS , by doing this , the sign changes from positive to neagative .

\(\longrightarrow y = 5 - 3x^2 \\\)

Step 2 :- Replace y with function notation \(f(x)\)

Just simply replace y here with f(x) as ,

\(\longrightarrow f(x) = 5 - 3x^2\\\)

Step 3 :- Find f(2) .

To calculate the value of f(2) , we need to put x = 2 , in the above equation as ,

\(\longrightarrow f(2) = 5 - 3(2)^2\\\)

Simplify,

\(\longrightarrow f(2) = 5 - 3(4)\\\)

\(\longrightarrow f(2) = 5 - 12\\\)

\(\longrightarrow \boxed{ \boldsymbol{f(2) = -7 }} \\\)

Answer: 72.36

Step-by-step explanation:

To find the total amount of salt in the bowl after Omar poured 13.2 grams, we need to add the initial amount of salt in the bowl to the amount of salt Omar added.

The initial amount of salt in the bowl was 59.16 grams.

Omar added 13.2 grams of salt to the bowl.

To find the total amount of salt in the bowl now, we add these two amounts: 59.16 + 13.2 = 72.36

Therefore, the bowl contains 72.36 grams of salt now.

The total surface area of the solid shape made from the cube and cylinder is approximately 583.31 cm².

The side length of the cube is 8.7 cm, so the surface area of one face is A = 8.7²

= 75.69 cm²

Since there are six faces, the total surface area of the cube is 6 * 75.69 = 454.14 cm²

Since there are two circular bases, the total surface area of the bases is 2 * 22.91 = 45.82 cm².

In this case, the radius of the cylinder is 2.7 cm and the height is 4.9 cm, so the curved surface area is A_curved = 2 * π * 2.7 * 4.9 ≈ 83.35 cm².

Total surface area = surface area of the cube + surface area of the cylinder

Total surface area = 454.14 cm² + 45.82 cm² + 83.35 cm²

Total surface area ≈ 583.31 cm²

The extra amount that Robby is to pay in interest to purchase the television is calculated as: $98

To calculate the extra amount paid in interest, you need to determine the total cost of the loan, including the interest, and subtract the original amount borrowed.

Here's the formula to calculate the extra amount paid in interest:

Extra Amount Paid in Interest = Total Cost of Loan - Original Amount Borrowed

Where, Total Cost of Loan = Original Amount Borrowed + Interest

To calculate the interest, you can use the following formula:

Interest = Original Amount Borrowed x Interest Rate x Time

The interest on the cash advance is calculated as follows:

$350 x 28% = $98

So, the total amount Robby will pay for the television after interest is:

$350 + $98 = $448

Therefore, the extra amount Robby will pay in interest to purchase the television is:

$448 - $350 = $98

There can be multiple outputs (monthly charges) for a given input (number of credit cards), violating the definition of a function. hence, Situation 3 does not represent a function.

Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned does not represent a function.

In a function, each input (or x-value) should have a unique output (or y-value). However, in this situation, the total amount of money charged monthly on credit cards depends on the number of credit cards owned. It is possible to have different credit card numbers but still have the same total amount of money charged monthly.

For example, two people could own different numbers of credit cards but have the same monthly charges.

As a result, the definition of a function can be violated by having many outputs (monthly charges) for a single input (number of credit cards).

Because of this, case 3 does not represent a function.

The cost of an entrance ticket on the trip to Spring Shot trampoline park is equal to $ \(16\frac{1}{2}\).

What do you mean by algebraic expressions ?

Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.

It is given that the total cost of trip for Lorenzo and his friends is $68.

Let's assume the cost of the entrance ticket be x.

The cost of entrance ticket for all of them = 4x

The fee added to entrance ticket is $2.

So , the algebraic expression can be written as :

2 + 4x = 68

reordering the like terms :

4x = 68 - 2

4x = 66

Dividing by 2 on both sides :

2x = 33

or

x = \(\frac{33}{2}\)

or

x = \(16\frac{1}{2}\)

Therefore , the cost of an entrance ticket on the trip to Spring Shot trampoline park is equal to $ \(16\frac{1}{2}\).
