Simplify 8 - (-5) - 4(-7)

The smaller number is 25 and larger number is 37

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here; The sum of two numbers is 62 and 3 times the smaller number exceeds twice the larger number by one.

let the smaller number be x and the larger number be y then we have

x+y=62

3x-2y=1

Thus solving this system of linear equations by method of elimination we get

5y=185

y=37

∴ x=25

Hence, The smaller number is 25 and larger number is 37

An equation that represents the linear function shown in the table or mapping diagram is y = -x/4 - 3.

In order to write an equation that represents the linear function, we would use the point-slope form. Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

Next, we would determine the linear function representing the line which passes through the data points (-4, 6) and (8, 3) by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 6 = (3 - 6)/(8 - (-4))(x - (-4))

y - 6 = (3 - 6)/(8 + 4)(x + 4)

y - 6 = -3/12(x + 4)

y - 6 = -x/4 - 9

y = -x/4 - 9 + 6

If f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.

What is a function?

A function is a mathematical object that assigns exactly one output to each input of a specified type. In other words, a function is a rule that takes in certain inputs (or "arguments") and produces a unique output. The inputs to a function are called the domain, while the set of possible outputs is called the range.

The given functions are f(x) = 3x and g(x)=x-2.

To find f(g(4)), we first need to evaluate g(4). The function g is defined as g(x) = x - 2, so g(4) = 4 - 2 = 2.

Next, we need to evaluate f(2), where f is defined as f(x) = 3x. So, f(2) = 3 * 2 = 6.

Therefore, f(g(4)) = f(2) = 6.

Hence, if f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.

2. To move from f(x) to g(x), four transformations are used:

A three-unit horizontal shift to the left: The graph thus shifts by a factor of -2 three units in the direction of the left  A vertical stretch.

You must first define the function and its domain before you can plot its graph. We can begin by sketching the piecewise linear graph of f(x) = |x|, which has a slope of 1 for x greater than 0 and -1 for x less than 0 in order to sketch the graph of g(x) = -2|x-3|+1. The vertical asymptote is shown by the x axis. For all real numbers, the definition of the f(x) graph exists.

Answer:

see below

Step-by-step explanation:

Step 1

5(x – 3) = x + 13

Step 2

See if x is a solution

5 (6-3) ?= 6+13

5 (3) ?= 19

15 ?= 19

Step 3

This is not true so it is not a solution

Step 4

5(x – 3) = x + 13

Distribute

5x-15 = x+3

Subtract x from each side

5x-x -15 = x+13-x

4x-15 = 13

Add 15 to each side

4x-13+13 = 15+13

4x =28

Divide each side by 4

4x/4 = 28/4

x = 7

7 is a solution

Answer:

First you substitute 6 for x!

5(6 - 3) = 6 + 13

6 - 3 = 3

The equation is now:

5 * 3 = 6 + 13

5 * 3 = 15

6 + 13 = 19

The result is:

15 = 19 which is not a true statement.

x is not equal to 6.

Now lets try 7.

5(7 - 3) = 7 + 13

7 - 3 = 4

7 + 13 = 20

5 * 4 = 20

Thus: x = 7

The numeric values of the function R(t) = 328 - 296e^(-0.004t) at t = 0 and t = 30 are given as follows:

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function for this problem is defined as follows:

R(t) = 328 - 296e^(-0.004t)

At t = 0, the numeric value is found replacing the lone instance of t by zero, hence:

R(0) = 328 - 296e^(-0.004(0))

R(0) = 32.

At t = 30, the numeric value is found replacing the lone instance of t by 30, hence:

R(30) = 328 - 296e^(-0.004(30))

For example, divisibility rules for 13 help us to know which numbers are completely divided by 13. Some numbers like 2, 3, 4, 5 have rules which can be understood easily. But rules for 7, 11, 13, are a little complex and need to be understood in-depth.

Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.

Example: 10, 20, 30, 1000, 5000, 60000, etc.

For any given number, to check if it is divisible by 13, we have to add four times of the last digit of the number to the remaining number and repeat the process until you get a two-digit number.  Now check if that two-digit number is divisible by 13 or not. If it is divisible, then the given number is divisible by 13.

For example: 2795 → 279 + (5 x 4)

We know that 100% of 800 is, well, just 800.Step 2: If 100% of 800 is 800, then we can get 1% of 800 by dividing it by 100. Let's do 800 / 100. This is equal to 8.0. Now we know that 1% is 8.0.Step 3: Now that we know what 1% of 800 is, we just need to multiply it by 67 to get our solution! 8.0 times 67 = 536. That's all there is to it!

The exact value of csc(A) is csc(A) = 7/20[√10]

From the question, we have the following parameters that can be used in our computation:

sec(A) = 7/3

Take the inverse of both sides

cos(A) = 3/7

Using the following trigonometry identity, we have

sin²(A) + cos²(A) = 1

Substitute the known values in the above equation, so, we have the following representation

sin²(A) + (3/7)² = 1

So, we have

sin²(A) = 40/49

Take the square roots

sin(A) = ±√(40/49)

The angle is in quadrant II

So, we have

sin(A) = √(40/49)

Take the inverse

csc(A) = √(49/40)

So, we have

csc(A) = 7√(1/40)

On solving the system of linear equations 3x + 3y = 45 and x + 2y = 24, the cost for each shirt is obtained as $6, and cost for each pair of pants is obtained as $9.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Let the cost of shirts be x and the cost of pair of pants be y.

The number of shirts bought by person A = 3

The number of pair of pants bought by person B = 3

The total cost for person A = $45

The equation for person A is -

3x + 3y = 45....(1)

The number of shirts bought by person B = 1

The number of pair of pants bought by person B = 2

The total cost for person B = $24

The equation for person B is -

x + 2y = 24....(2)

Multiply equation (2) by 3 -

3(x + 2y) = 24 × 3

3x + 6y = 72....(3)

Subtraction equation (1) from equation (3) -

3x + 6y - (3x + 3y) = 72 - 45

3x + 6y - 3x - 3y = 27

3y = 27

y = 9

Substitute the value of y in equation (2) -

x + 2(9) = 24

x + 18 = 24

x = 24 - 18

x = 6

Therefore, the cost of shirts and pants is x = 6 and y = 9 respectively.
