What is the inverse of the given relation? y=3x+12 Show your work.

Answer:

28-c3+6=0

Collect like terms

28-6=c3

22=c3

Divide both sides by 3

22/3=c3/3

C=7

To evaluate the expression 28-c3+6, you must know the value of 'c'. Assuming c3 means c cubed, then you would calculate 'c' cubed, subtract it from 28 and then add 6. Without a value for 'c', we cannot compute a definitive answer.

To solve this mathematical expression, we must first understand what c3 means. In this case, 'c' and '3' are variables and without a given value for 'c' we cannot fully evaluate it. However, if we assume that 'c3' means 'c' cubed then, we can proceed with that understanding. Cubing a number means multiplying it by itself twice. For example, if c=2, then c cubed would be 2*2*2=8.

Next step is to follow the rules of the order of operations, often remembered by the acronym PEMDAS - Parentheses, Exponents, Multiplications and Divisions (from left to right), Additions and Subtractions (from left to right).

Therefore, given the expression 28-c3+6, you would first calculate 'c' cubed and then perform the remaining operations from left to right. If 'c' was 2, your expression would look like this: 28-8+6. Following PEMDAS, subtraction comes before addition, so you subtract 8 from 28 which is 20 and then add 6 to that, giving a result of 26. But remember, without knowing the true value of 'c', we cannot definitively solve the expression.

The high temperature in degrees Fahrenheit was [tex]\( 59^\circ \)[/tex] Fahrenheit.

To convert a temperature from Celsius to Fahrenheit using the formula  F = 1.8C + 32, where F is the temperature in Fahrenheit and C is the temperature in Celsius, you simply plug in the value of C and solve for F.

Given that the high temperature in the mountain city was [tex]\( 15^\circ \)[/tex] Celsius, we can plug this value into the formula:

F = 1.8 * 15 + 32

F = 27 + 32

F = 59

zxy or xyz or z×x×y

Final answer:

The mathematical expression for 'the product of z, x, and y' is simply 'zxy' or 'z  times x  times y', which indicates that the three variables are being multiplied together to form a product.

Explanation:

To translate "the product of z, x, and y" into a mathematical expression, we represent multiplication using either the multiplication sign (times) or simply by juxtaposition (placing the variables next to each other). Thus, the product of the variables z, x, and y is represented as z  imes x  imes y or simply as zxy. This expression shows that z, x, and y are being multiplied together to give a Mathematical Result.

In mathematics, when expressions are evaluated and produce the same value, they are known as equivalent expressions. For example, the expression (5 - 3xy) is evaluated by following the order of operations, which in this case involves subtracting the product of 3 and xy from 5. If x, y, and z are treated as three independent variables, it is also possible to represent their product in the form of a Multiple or Product, like so: xyz.

"Mitchael owes $8 to his bank, so he decides to add $60 in April at a rate of $2 per day. How many days Mitchael needs in order to get $28 in his account?"

Hello! Remember you have to write clear questions in order to get good and exact answers. The given equation doesn't make any sense so I'll assume the correct one is:

[tex]-8+60x=28[/tex]

So let's write a real world problem you could answer by solving the equation:

"Mitchael owes $8 to his bank, so he decides to add $60 in April at a rate of $2 per day. How many days Mitchael needs in order to get $28 in his account?"

So by isolating x (number of months):

[tex]x=\frac{28+8}{60} \\ \\ x=0.6 \ month \\ \\ \\ Since \ we \ need \ the \ number \ of \ days: \\ \\ April \ has \ 30 \ days, \ so: \\ \\ x-day=0.6\times 30=18 \ days[/tex]

So Mitchael would need 18 days in order to get $28 in his account

To solve the equation -8+60=28, we follow basic arithmetic by adding the positive payment to the negative debt which gives us 52. This answer indicates an error in the original problem statement, as the expected balance does not match with the calculated one.

A real-world problem that could be answered by solving the equation -8+60=28 might involve a scenario where someone is tracking their financial transactions. Suppose you start with a debt of \(-8 dollars and then receive 60 dollars as a payment of some sort. The question could be to determine how much money you have after receiving the payment. To find out, you would solve the equation to see if your final balance is 28 dollars as expected.

Let's solve this step-by-step:

Add the amount received to the initial debt: \( -8 + 60 \).

Calculate the sum which gives us \( 52 \).

Therefore, after receiving the payment, you have 52 dollars.

To answer the original equation, the final balance should be 28 dollars; however, the solution we found is 52 dollars, indicating there might be a mistake in the original problem statement or the transactions recorded.

Simplifying

3x + 2(4x + -4) = 3

Reorder the terms:

3x + 2(-4 + 4x) = 3

3x + (-4 * 2 + 4x * 2) = 3

3x + (-8 + 8x) = 3

Reorder the terms:

-8 + 3x + 8x = 3

Combine like terms: 3x + 8x = 11x

-8 + 11x = 3

Solving

-8 + 11x = 3

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 11x = 3 + 8

Combine like terms: -8 + 8 = 0

0 + 11x = 3 + 8

11x = 3 + 8

Combine like terms: 3 + 8 = 11

11x = 11

Divide each side by '11'.

Answer:

0.073

Step-by-step explanation:

The question is about growth function and you are asked to find out the growth rate. Growth function has a format of

y = a(1+r)^t

Where

y= future value = S(t)

a= current value = 273

r= growth rate

t= time =t

Since its a growing function, the r will be positive. If its decay function then the r will be negative. As you can see, the growth rate value is located inside the parentheses. The growth rate of the function should be:

(1+r)= (1.073)

r= 1.073- 1

r= 0.073

⇒ SI = $9282

To solve the equation 3 + 4n/n = 7b for n, you can cancel out the n in the numerator and denominator. Then, subtract 3 from both sides of the equation and divide by 7 to solve for b.

To solve the equation 3 + 4n/n = 7b for n, we need to isolate n on one side of the equation. First, we can simplify the equation by canceling out the n in the numerator and denominator, as they are dividing each other. This leaves us with 3 + 4 = 7b. Next, we can subtract 3 from both sides of the equation to get 4 = 7b - 3. Finally, we can divide both sides of the equation by 7 to solve for b: 4/7 = b.

Answer:

Explanation:

The figure attached shows the three squares that you have to fill to complete the table to summarize the different theorems to prove triangles are congruent.

1. SAS

SAS stands for Side Angle Side. That means that whenever two sides and the included angle on one triangle are congruent to two sides and the included angle of another triangle, then those two triangles are congruent.

Thick marks are used to mark the corrsponding parts, sides or angles that are congruent. That is why the two triangles to the first triangles on the image (on the upper square to the right) are marked:

In that way, the figures show two triangles, with two congruent sides and the included angle congruent, to prove that the two triangles are congruent by the SAS theorem.

2. ASA

ASA stands for Angle Side Angle.

The ASA congruency theorem states that if two angles of a triangle and the included side are congruent, then the two triangles are congruent.

Thus you have to add the legend "Two congruent angles with and included side", which means that if the two angles and the included side on one triangle are congruent to two angles and the included side of other triangles, then both triangles are congruent.

The rule to mark the sides and angles that are congruent is with the use of thick marks. This is how it was done in the drawing of the two triangles in the lower right square:

Answer:

[tex]average\ speed = 36\ mi/hr[/tex]

Step-by-step explanation:

Given:

Each city is exactly 120 miles from the other two.

Average rate from city A to city B = 60 mi/hr

Average rate from city B to city C = 40 mi/hr

Average rate from city c to city A = 24 mi/hr

We need to find the Dale's average rate for the entire trip.

Solution:

First we find the total time and total distance by following way.

Time taken to travel from A to B = [tex]\frac{Distance}{Speed} = \frac{120}{60}= 2\ hr[/tex]

Time taken to travel from B to C = [tex]\frac{Distance}{Speed} = \frac{120}{40}= 3\ hr[/tex]

Time taken to travel from C to A = [tex]\frac{Distance}{Speed} = \frac{120}{24}= 5\ hr[/tex]

So, total time taken = [tex]2+3+5=10\ hr[/tex]

Total distance =  120 + 120 + 120 = 360 miles

Using average speed formula.

[tex]average\ speed = \frac{Total\ distance}{Total\ time\ taken}[/tex]

[tex]average\ speed = \frac{360}{10}[/tex]

[tex]average\ speed = 36\ mi/hr[/tex]

Therefore, the average rate for the entire trip [tex]average\ speed = 36\ mi/hr[/tex]
