Answer:

It's A.

Step-by-step explanation:

For every value of x there is one value of y  - we can draw a vertical line through any value of x and it will pass through only one value of y.

Therefore it is a one-to-one function.

Answer:

Option A

Step-by-step explanation:

The curve given is an increasing curve cutting x axis once and y axis once.

Any vertical line cuts only once the curve. Hence this is a function only.

We find that for every y in the range there is only one x corresponding to that.

Hence this curve is not a many to one curve.  It is not linear because it is not  a straight line.  It is a function.

Hence only correct option is

a) The curve is a one to one function.

➷ First, just divide the numbers:

12/4 = 3

When dividing values with exponents, you have to subtract the exponents:

7 - 5 = 2

Therefore, your answer would be option B. 3b^2

Step-by-step explanation:

I am assuming that you meant the following:

 12b^7

------------

  4b^5

Note that " ^ " is the proper symbol for exponentiation, and " * " for multiplication.

12/4 = 3 and b^7 / b^5 = b^2.  Thus,

 12b^7

------------ = 3b^2 (or, better yet, 3b²).

Answer:

Choose the best estimate for the capacity of a bath tub

A. 5 ml

B. 500 ml

C. 50 cl

D. 500 L

Step-by-step explanation:

The best estimate for the capacity of a bathtub is 500 Liters (500L) as it provides a measure that is comparably similar to the actual volume of a bathtub.

The best estimate for the capacity of a bathtub would be  500 Liters (500L). This is because the capacity of a bathtub is usually much larger than a litre. Option A and B provide measurements in millilitres, which are much smaller units (a liter is 1,000 millilitres), and thus would not be sufficient to measure a bathtub's capacity. Option C is calling for centilitres, where 1 centilitre is equivalent to 10 millilitres, still way smaller than a bathtub's capacity. Hence, 500L (500 Litres) is the most reasonable estimation for the capacity of a bathtub.

Answer:

84 is your answer

Step-by-step explanation:

What you are doing is multiplying them together.

87,1/2% put into a calculator comes out to 7/8 or .875.

You will take that and multiply it to 96

7/8*96=84.

They’re aren’t any pictures you provided but I can still assist you a little. It’s starts at 6:25 so you add 3 hours then add 15 minutes.

So add 6 hours + 3 hours = 9 hours, then do 25+15 = 40

The college graduate will have received a total income of $699,848.22 after ten years, starting with a salary of $60,000 and increasing by 4% each year.

To find the total income the college graduate will have received after ten years, we need to calculate the salary for each year and sum them up. The first year salary is $60,000. After that, the salary increases by 4% each year. To calculate the salary for each subsequent year, multiply the previous year's salary by 1.04. Here are the calculations for each year:

Now, sum up the salaries for each year:

Total income after ten years = $60,000 + $62,400 + $64,896 + $67,491.84 + $70,190.95 + $72,999.66 + $75,923.45 + $78,967.79 + $82,138.35 + $85,440.18 = $699,848.22

Therefore, the college graduate will have received a total income of $699,848.22 after ten years.

The college graduate will receive a total income of approximately $720,360 over ten years.

1. To calculate the total income a college graduate will receive over ten years with an initial salary of $60,000 and a 4% annual raise, we can use the formula for the sum of a geometric series.

2. The formula for the sum of the first n terms of a geometric series is given by:

Sum = a(1 - [tex]r^{n}[/tex]) / (1 - r)

3. Substituting the given values:

a = 60,000, r = 1.04, n = 10

Sum = 60,000 * (1 - [tex]1.04^{10}[/tex]) / (1 - 1.04)

Sum = 60,000 * (1 - 1.48024) / ( -0.04)

Sum = 60,000 * (-0.48024) / (-0.04)

Sum = 60,000 * 12.006

Sum ≈ 720,360

4. Total Income:

Thus, the total income received after ten years is approximately $720,360.

Opposites in the numbers world refer to numbers that have the same absolute value, but one is negative, while the other is positive.

For a real world example, consider if you have your friend 5 dollars. The amount you have in the transaction is the opposite of the amount he has in the transaction.

The opposite of a number X is that number that when added to X produces zero. The opposite of X is denoted with −X.

The opposite of a number has the same absolute value as the number but an opposite sign. For example, the opposite of 1 is equal to −1 because 1 + (−1) = 0.

The opposite of zero is zero. This is the only number whose opposite is equal to itself. So zero is the neutral element with regard to addition.

In turn, the opposite of a complex number corresponds to a rotation of 180°.

Answer:

2/6, which equals 1/3

Step-by-step explanation:

if the die has six sides, the probability that he will roll 2 again is 1/6 since there’s only one 2 out of the six sides

The probability jack will get 2 on the next roll is 1/6.

It is the ratio that determines how likely a certain event can occur within a set of possible events.

The given dice has 6 sides.

The number 2 occurs only on one side of a die.

Therefore, if he were to roll the dice one more time, the probability that he would get 2 can be given by 1/6.

Therefore, the probability that jack will get 2 on the next roll is 1/6.

Answer:

terms: 2x, 3y

like terms: n/a

coefficients: 2, 3

constants: 7

Step-by-step explanation:

terms: matching variables

coefficients: numbers in front of the variable

constants: number that does not change

Answer: A

put x = 3 into f(x)=6x and you get f(x) = 18

Put x = 4 into f(x) and you get f(x) = 24

Subtract those two. 24 - 18 = 6

Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.

Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,

6(x+1) = 6x + 6.

+6, it increases.

Answer:C: f(x) increases by factor of 9

Answer:

1-ELIMINATION.

2- SUBSTITUTION.

3- GRAPHING.

Step-by-step explanation:

Methods:

1- Elimination:

- Line up the variables.

- To cancel out one of the variables, you need to make that the coefficient of that variable opposite. For example:

[tex]\left \{ {{3x+y=1} \atop {-3x+4y=3}} \right.[/tex]

As you can see, the coefficient of x in the first eqation is 3 and -3 in the second option.

- Add the equations.

- Solve for the the variable that is still present.

- Substitute the value of the variable obtained into one of the original equations.

- Solve for the other variable.

2- Substitution:

- Solve for one of the variables from any of the equations of the system.

- Substitute into the other equation for that variable.

- Solve for the other varible to find its value.

- Substitute the value obtained into any of the original equations and solve for the other variable.

3- Graphing:

- Rewrite the equations as equtions of the line slope intercept form ([tex]y=mx+b[/tex], where m is the slope nd b the y-intercept).

- Graph each line.

-  Then:

If there ir an intersection point of the two lines, then that point is the solution to the system

If the lines are the same, there are infinitely many  solutions.

If the lines are parallel, then there is no solution

the answer is y=3x-1

the 3 comes from the point moving 3 up and 1 right and the -1 comes from the y intercept

Answer:

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y = mx + b

m - slope

b - y-intercept

From the graph we have the y-intercept: (0, -1). Therefore b = -1.

y = mx - 1

From the graph we have the second point (1, 2). Put the coordinates of this point to the eqution:

2 = m(1) - 1

2 = m - 1               add 1 to both sides

3 = m

Finally we have

y = 3x - 1

Final answer:

To find f(8) for f(x) = 2x - 7, plug 8 into the equation and simplify: f(8) = 2(8) - 7, which equals 9.

Explanation:

To find the value of the function f(x) at x = 8, you simply substitute the value of 8 into the function. Given f(x) = 2x - 7, substituting 8 for x gives us:

f(8) = 2(8) - 7

Now, multiply 2 by 8:

f(8) = 16 - 7

Then, subtract 7 from 16:

f(8) = 9

Therefore, the value of the function f(x) when x = 8 is 9.
