Switch the variable x and y with each other. Then the correct option is B.

What is inverse of a function?

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

f(x) = 3x – 10

Then the inverse function of the f(x) will be

Put y in place of f(x).

    x = 3y – 10

  3y = x + 10

    y = (x + 10) / 3

Switch the variable x and y with each other.

Then the correct option is B.

Answer:

Option A

Step-by-step explanation:

Hello!

We can find the graph by finding the roots of the equation.

Since the equation is already in factored form, we can use the Zero Product Property to find the roots. The roots of an equation are the value(s) of x when y is 0 (x-axis).

Find the Rootsy = (x - 2)(x - 3)0 = (x - 2)(x - 3)0 = (x - 2)
x = 20 = (x - 3)
x = 3

The roots of the equation are 2 and 3. That means the graph intersects the x-axis at points 2 and 3. Looking at the graphs shown, the answer is Option A.

Answers

Hence, The value of x in the congruent triangles abc and dec is 1

What is geometry?

the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.

How to solve?

The question implies that the triangles abc and dec are congruent triangles.

The congruent sides are,

ab = de

bc = ce = 4

ac = cd = 5

The congruent side ab = de implies that,

4x - 1 = x + 2

Collect like terms,

4x - x = 2 + 1

Evaluate the like terms,

3x = 3

Divide through by 3

x = 1

Hence, the value of x is 1

Answers

Answer:

6/5 or 1.2, they're the same value

Step-by-step explanation:

When it says "rate of change", it's really just asking for the slope. If you don't know what the slope is, essentially how much the y-value increases by whenever x increases by 1. This can be formally defined using the equation: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] which is essentially [tex]\frac{rise}{run}[/tex]. The subtraction is finding the difference between the two numbers to see how much it's changed by. Btw the order doesn't matter, I could plug in (-3, -2) as (x2, y2) or I could plug it in as (x1, y1) as long as I make sure to input it in correctly. In this example I'll just say (-3, -2) = (x1, y1) and (2, 4) = (x2, y2). Plugging these values into the equation gives you: [tex]\frac{4- (-2)}{2- (-3)} = \frac{6}{5}[/tex] that's the rate of change

Answers

The quadratic equation is y = 1/2x^2 - 3x + 4

How to determine the equation?

A quadratic equation is represented as:

y = ax^2 +bx + c

Using the values on the table, we have:

a(0)^2 + b(0) + c = 4 ---- when x = 0

a(2)^2 + b(2) + c = 0 ---- when x = 2

a(4)^2 + b(4) + c = 0 ---- when x = 4

Evaluate these equations

c = 4

4a + 2b + c = 0

16a + 4b + c = 0

Substitute c = 4

4a + 2b + 4 = 0

16a + 4b + 4 = 0

Divide through by 2 and 4

2a + b + 2 = 0

4a + b + 1 = 0

Subtract both equations

2a -1 = 0

Solve for a

a= 1/2

Substitute a= 1/2 in 4a + b + 1 = 0

4 * 1/2 + b + 1 = 0

Evaluate

2 + b + 1 = 0

Solve for b

b = -3

So, we have:

y = ax^2 +bx + c

This gives

y = 1/2x^2 - 3x + 4

Hence, the quadratic equation is y = 1/2x^2 - 3x + 4

What is the smallest possible length of the hypotenuse for a non-degenerate
right triangle with integer side lengths given that it has at least 1 leg of length
84.

Answers

The smallest possible length of the hypotenuse is 118

How to determine the hypotenuse?

The given parameters are:

Triangle type: non-degenerate right triangleLegs: Length = 84 (at least 1)

The non-degenerate implies that the right triangle has a positive area.

Since at least one length is 84, then both lengths can also be 84.

The hypotenuse is then calculated using the following Pythagoras theorem.

h^2 = 84^2 + 84^2

Evaluate the sum

h^2 = 14112

Take the square root of both sides

h = 118.8

Round down

h = 118

Hence, the smallest possible length of the hypotenuse is 118

Answers

The experimental probability is 5/14.

What is Experimental Probability?The term "probability" refers to an event's likelihood of happening. A probability has a value between 0 and 1, therefore if an occurrence is impossible, it has a probability of 0, and if it is certain, it has a probability of 1. Experimental probability is the probability that is established based on the outcomes of an experiment. The term "empirical probability" also applies to this. A probability that has been established by a series of tests is called an experimental probability. To ascertain their possibility, a random experiment is conducted and iterated over a number of times; each iteration is referred to as a trial. The goal of the experiment is to determine the likelihood that an event will occur or not.

Since, 4 appeared five times over the total, The experimental probability is 5/14.

Step-by-step explanation:

First, lets convert Robert's pace to metres. (cm > m)

= 0.75m

Number of Full Paces = Length of Bridge / 1 Full Pace

=

Step-by-step explanation:

the ratio of girl to boys is 6 2, there were 14 boys how many total members were there in the club

Answers

Answer:

The club has 56 members

Step-by-step explanation:

We can set up a ratio problem to find the total number of kids in the club. There are two ways to do this, and I will show you both. The first way is to immediately set up a ratio between the number of boys and the number of total members in the club. Since the ratio of girls to boys is 6:2, the ratio of boys to members is 2:8 (add the number of girls and boys in the ratio to get the total number of people). Now, we can set up an equation, letting x equal the number of members total, and solve using cross multiplication:

[tex]\frac{2}{8}=\frac{14}{x}\\\\ 112=2x\\\\ x=56[/tex]

The other way to solve this problem would be to figure out the number of girls in the club if there are 14 boys and then add the two quantities together. If we let y be the number of girls in the club, we get the following solution:

[tex]\frac{6}{2}=\frac{y}{14}\\\\ 2y=84\\\\ y=42\\\\x+y=56[/tex]

Either way, we get that the total number of members is 56

Write an algebraic expression for each statement:

b. The tens digit of a number is b and the units digit is twice as big. What is the value of the number in terms of b if the digits are reversed?

I hope you can help me with these questions!!

Answers

For the given sentences, the algebraic expressions are:

a) N = 110*c - 300

b) N = 12*b

How to get the algebraic expressions?

For the first statement:

A 3-digit number, where the tens digit is c, can be written as:

N = 100*a + 10*c + b

Then the hundreds digit is a, and here we know that is 3 less than the tens digit, then:

a = c - 3

The ones digit is b, here we know that it is 0, then b = 0.

Replacing that in our number we get:

N = 100*(c - 3) + 10*c = 110*c - 300

N = 110*c - 300

That is the algebraic expression.

b) A two-digit number can be written as:

N = b*10 + a

Where b is the tens digit and a is the ones digit.

Here we know that the units digit is twice as bit as the tens digit, then:

a = 2b

Replacing that we get:

N = b*10 + a = b*10 + 2b = 12*b

N = 12*b

That is the algebraic expression.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Segments pr and pq are partitioned in the ratio 3:2, hence:

[tex]PR = \frac{3}{5}PQ[/tex]

[tex]R - P = \frac{3}{5}(Q - P)[/tex]

The points are:

For the x-coordinate, we have that:

[tex]R - P = \frac{3}{5}(Q - P)[/tex]

[tex]x - 6 = \frac{3}{5}(-2 - 6)[/tex]

x - 6 = -4.8

x = 1.2.

For the y-coordinate, we have that:

[tex]R - P = \frac{3}{5}(Q - P)[/tex]

[tex]y + 5 = \frac{3}{5}(4 + 5)[/tex]

y + 5 = 5.4.
