Answer:

Inverse of function  f(x) is y =x-3

Step-by-step explanation:

Given:

f(x) = (x+3)

To Find:

Inverse of  f(x)

Solution:

Inverse of the function:

Let f: X -> Y be a function with domain X and target set Y. Then g is the inverse of f if g is a function with domain Y and target set X such that

g(f(x)) = x for all x in X

f(g(y)) = y for all y in Y.

f has an inverse function if and only if f is both one-to-one and onto. If f is one-to-one and onto, then its inverse function g is defined implicitly by the relation g(f(x)) = x.

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

Let y = f(x) = x+3

So, swapping the variables: y=x+3 becomes x=y+3

Now, solve the equation x=y+3 for y.

y=x−3

y=x−3

4.5 x 4= 18

Answer:

6.4

Step-by-step explanation:

#1. 3x+1.5=2.5x+4.7

#2. subtract by 1.5 on both sides

#3. 3x=2.5x +3.2

#4. then subtract 2.5x on both sides because you need all the x'x on one side

#5. .5x= 3.2

#6. then you divide but you should bring the decimal to the right once on both sides

#7. x=6.4

The equation 3x + 1.5 = 2.5x + 4.7 has one solution which is x = 6.4.

The equation at hand is 3x + 1.5 = 2.5x + 4.7. To check whether the equation has no solution, one solution, or an infinite number of solutions, we have to solve the equation.

By collecting like terms, 3x - 2.5x = 4.7 - 1.5 will give us 0.5x = 3.2. To isolate x, we simply divide both sides of the equation by 0.5, leading to x = 3.2/0.5 which equals 6.4.

Therefore, the given equation has one solution, and that solution is x = 6.4.

Answer:

[tex]y=3x+1[/tex]

Step-by-step explanation:

From the question, we are given;

We are required to determine the equation of a line parallel to the given line and passing through the point (-1, -2)

y = 3x + 2, m₁ = 3

Taking another point (x, y)...

Then;

[tex]\frac{y+2}{x+1}=3[/tex]

[tex]y+2=3(x+1)\\y+2=3x+3\\y=3x+1[/tex]

Therefore; the equation of the line is [tex]y=3x+1[/tex]

Answer: n ≥ 4

Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation which is to get x by itself on one side of the inequality.

Since 3 is being subtracted from 2n, add 3 to both sides of the inequality to get 2n ≥ 8. Now since n is being multiplied by 2, we need to divide by 2 on both sides of the inequality to get n ≥ 4.

Our next task is to graph n ≥ 4 on a number line and to do that, we start with a closed dot at 4. The reason we use a closed dot at 4 is because not only is n greater than 4 but it's also equal to 4. Next we draw an arrow going to the right on our number line to represent all numbers greater than 4.

When graphed, it should look something like the image attached.

Answer:

12 = 22 × 3

Step-by-step explanation:

The fraction equivalent of 7/12% of a quantity is 7/12000.

The question is asking to derive the fraction equivalent of 7/12% of a quantity. In mathematics, a percent is a way of expressing a fractional amount using a ratio whose denominator is 100. Therefore, to convert a percent to a fraction, we write the value of the percent as a fraction with a denominator of 100.

In this case, 7/12% can be expressed as (7/12)/100. Simplifying this fraction, we get 7/12000, which is the fraction of the quantity that 7/12% represents.

Therefore Mr. Torres buys 1 pound of ground beef and 8.5 pounds of chicken.

Step-by-step explanation:

i) Let x be the number of pounds of ground beef

ii) Let y be the number of pounds of chicken.

iii) therefore    x + y = 9.5 pounds

iv) also we have   4.5 x +  3 y  = 30 dollars

v) multiplying the equation in iii) by 3 we get   3x + 3y = 28.5

vi) Subtracting the equation in v) from the equation in iv) we get  1.5 x  =  1.5

vii) Therefore x  = 1 pound

viii) substituting the value of x in vii) in the equation in iii) we get

    1 + y  = 9.5 .  Therefore y = 8.5 pounds.

ix) Therefore Mr. Torres buys 1 pound of ground beef and 8.5 pounds of chicken.

The perimeter of a rectangle is 34 units. Its width W is 6.5 units.

Write an equation to represent the perimeter in terms of the length L, and find the value of L

The length of rectangle is 10.5 units

Given that,

Perimeter of rectangle = 34 units

Width of rectangle = 6.5 units

Let "L" be the length of rectangle

The perimeter of rectangle is given by formula:

Perimeter = 2(length + width)

Substituting the values we get,

[tex]34 = 2(L + 6.5)[/tex]

Thus the equation is found

Solve for "L"

[tex]L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5[/tex]

Thus length of rectangle is 10.5 units

To determine the number of different sets of 8 songs possible for Janine's play list, we have to use the combination formula of combinatorics. Combinatorics is a branch of mathematics concerning the study of countable or finite discrete structures. The combination is a selection of items where order does not matter. The formula for combination is: C(n, r) = n! / [r!(n-r)!]

where:

Therefore, to answer the question, we would need to know the total number of songs available to Janine. Once we know that, we can substitute that number for 'n', and use the formula to calculate.

The expression 3(2x-8)-11x simplifies to -5x - 24 by distributing the 3 and then combining like terms.

To simplify the expression 3(2x-8)-11x, we must first distribute the 3 to both terms within the parenthesis and then combine like terms. Here's the step-by-step process:

Multiply 3 by 2x to get 6x.

Multiply 3 by -8 to get -24.

Combine the products from steps 1 and 2 with the -11x.

So, 3(2x-8) equates to 6x-24.

Now, combine 6x - 24 with -11x (6x-24-11x).

Simplify the like terms by subtracting 11x from 6x which gives -5x.

Our final expression is -5x - 24.

Therefore, the simplified expression of 3(2x-8)-11x is -5x - 24.

Answer:

The constant m=-4, and b=33

Step-by-step explanation:

F(x)= MX+b

If f(6)=9 then x=6, m= -4

9= -4(6) + b

9= -24 + b

b= 9 + 24

b= 33

Therefore the constant m, which is the slope is -4 and b which is the intercept is 33

Given the linear function f(x) = mx + b, we see the slope m as -4. Using the point (6,9), we find the y-intercept b to be 33.

In the linear function 'f(x) = mx + b', 'm' represents the slope of the line and 'b' is the y-intercept. As it's given that the slope is -4, we replace 'm' in the equation with -4 to get 'f(x) = -4x + b'. Now, we use the point (6,9) which lies on the line, allowing us to find the value of 'b'. Substituting x = 6 and f(x) = 9 into the equation, we get 9 = -4*6 + b. After solving this equation, we find that b = 33. Therefore, the constants are m = -4 and b = 33.

The width of rectangular garden(b) = 8 feet and

The area of rectangular garden = 160 square feet

Step-by-step explanation:

Given,

The length of rectangular garden(l) = 20 feet and

The perimeter of rectangular garden(fencing) = 56 feet

To find, the width of rectangular garden(b) = ? and

The area of rectangular garden = ?

We know that,

The area of rectangular garden = 2(l + b)

⇒  2(20 + b) = 56

⇒  20 + b = 28

⇒ b = 28 - 20 = 8 feet

The width of rectangular garden(b) = 8 feet

∴ The area of rectangular garden = l × b

=  20 feet × 8 feet

= 160 square feet

Hence, the width of rectangular garden(b) = 8 feet and

the area of rectangular garden = 160 square feet

The width of Julia's garden is 8 feet, and the area of her garden is 160 square feet. The calculations were made using the perimeter and area formulas for rectangles.

To find the width of Julia's rectangular garden and its area, we can use the given information:

The garden is 20 feet long, and the total perimeter of the garden is 56 feet.

Step-by-Step Solution:

The formula for the perimeter P of a rectangle is given by:

P = 2L + 2W

where L is the length and W is the width.

We know the following values:

L = 20 feet

P = 56 feet

Substitute these values into the perimeter formula:

56 = 2(20) + 2W

Simplify and solve for W:

56 = 40 + 2W

56 - 40 = 2W

16 = 2W

W = 8 feet

Now we can find the area A of the garden using the formula for the area of a rectangle:

A = L × W

Substitute the values we have:

A = 20 × 8

A = 160 square feet

The width of Julia's garden is 8 feet, and the area of her garden is 160 square feet.

The Elimination Method is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.

When multoplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).

23+x=30

x=30-23

x=7

\therefore Mean=\frac{1 \times 7 + 2 \times 1+ 3 \times 3 + 4 \times 2 + 5\times 2}{15}

                      =\frac{7+2+9+8+10}{15} =\frac{36}{15} =2.4
