The linear equation that represents this situation will be y = 4x + 3.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

As ΔABC ≅ ΔDEF, Using congruence properties the value of x= 5 and the value of y= 14.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Given that ΔABC ≅ ΔDEF, so that

AB ≅ DE

BC ≅ EF

AC ≅ DF

and AB = 8

BC = 19

AC = 14

EF = 4x-1

DE = y-6,

As AB ≅ DE

8 = y - 6

add 6 both sides we get

y = 8 + 6

y = 14

and BC ≅ EF

19 = 4x - 1

Add 1 both sides we get

4x = 19 + 1

4x = 20

divide both sides by 4 we get

x = 20/4

x = 5

Answer:

assuming that it can be solved, then yes

Step-by-step explanation:

The table that represents a linear relationship that is also proportional is; Table B

In Mathematics, a proportional relationship can be defined as a type of relationship that generates equivalent ratios and as such it can be modeled or represented by the following mathematical expression:

y = kx

Where:

x and y represents the variables.

k represents the constant of proportionality.

For us to have a proportional relationship and equivalent ratios, the variables x and y must have the same constant of proportionality.

Next, we would determine the constant of proportionality (k) using table B as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = -2/-1 = 2 or 2/1 = 2

Constant of proportionality (k) = 2

Thus, table B is correct.

Step-by-step explanation:

In order to score at least 76 for the full course, you have to score a total of 70 marks on the third test.

Average is calculated by first adding all the values of the total number of terms in a problem by the total number of terms.

Suppose there are five terms in a given problem, the formula will stand as:

Average of five terms = (n1 + n2 + n3 + n4 + n5)/5.

In this problem, the score of the first two tests are provided and the average of the three final tests is provided.

Marks scored in 1st test = 70

Marks scored in 2nd test = 88

Average marks = 76

Let the score of the third test be [tex]x[/tex]

Therefore, (70 + 88 + [tex]x[/tex])/3 = 76

(158 + [tex]x[/tex])/3 = 76

158 + [tex]x[/tex]= 228

[tex]x[/tex]= 228-158 = 70

Hence, the test score of the third test has to be 70 in order to get an average of 76 in the final marks.

Answer:

(-2,2)

Step-by-step explanation:

First, let's look at the 2 inequalities:

y ≤ -x + 1

y > x

Just by looking at the second inequality, we can remove any ordered pairs where x is greater than or equal to y. This eliminated the ordered pairs (-1,-3) and (0,-1). Now, the answer has to be (-3,5) or (-2,2). Knowing this, we can plug x and y into the equation and see if either of the answers are true.

(-3,5):

x = -3

y = 5

y ≤ -x + 1

5 ≤ -(-3) + 1

5 ≤ 3 + 1

5 ≤ 4

NOT TRUE

(-2,2)

x = -2

y = 2

2 ≤ -(-2) + 1

2 ≤ 2 + 1

2 ≤ 3

TRUE

So, since plugging in the ordered pair (-2,2) into the inequality gives us a true answer while (-3,5) doesn't, the order pair (-2,2) must be out answer.

The quantity of 68% hydrochloric acid solution must be mixed are;

94 ml of 68% Acid type I

1,535.33 ml 16.00% acid type II

The quantities and percentages given are;

Acid type I 68% ---------------- x liters

Acid type II 16% ------ 1629.33 - x liters

Mixture 19% ---------------- 1629.33

Thus, by combination of the values given we have;

68% x + 16%(1629.33 - x ) = 19% * 1629.33

Multiply through by 100 to get;

68x + 16(1629.33 - x ) = 30957.27

68x + 26069.28 - 16x = 30957.27

68x - 16 x = 30957.27 - 26069.28

52x = 4,887.99

x = 4,887.99/52

x = 94 ml of 68% Acid type I

Acid type II 16% ------ 1629.33 - 94

The value of exterior angle is 108°.

What are exterior angles ?
An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side.

Given:

Interior angles : (a+10)° and 44°

Thus , we know that

Exterior angle  = sum of interior opposite angles

Therefore , Exterior angle  = (a+10)° + 44°

or

2a° = (a+10)° + 44°

or

a = 54°

Therefore , exterior angle = 2a = 2*54° = 108°

Thus , the value of exterior angle is 108°.

So, approximately 2.28% of the observations are less than 140.

To find the percentage of observations that are less than 140, we need to find the standard score (z-score) that corresponds to 140, and then use a standard normal table to find the proportion of data that is less than that z-score.

The standard score is calculated as follows:

z = (140 - 130) / 5 = 2

Using a standard normal table, we can find the proportion of data that is less than 2 standard deviations from the mean. This proportion is approximately 0.0228 or 2.28%.

Yes, his pulse rate is in the normal range for children. His pulse rate was calculated to be 120 beats per minute, which falls within the range of 60-100 beats per minute.

The student took his resting pulse rate by counting the number of beats in 20 seconds. He then multiplied his result by three to calculate his pulse rate for a minute. To determine if his pulse rate was within the normal range for children, he compared his result to the data shown in the table. His pulse rate of 120 beats per minute was within the range of 60-100 beats per minute, so it was considered to be normal for children. To ensure accuracy, the student could have taken his pulse rate for a longer period of time, such as 30 or 60 seconds, before calculating his pulse rate for a minute.

The decimal number that corresponds to the binary number 11111111 is 255.

The decimal numeral system is the most widely used system for representing both integer and non-integer values. It is the Hindu-Arabic numeral system's expansion to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system. A decimal number is made up of two parts: a whole number and a fractional component separated by a decimal point. The decimal point is the dot between the whole number and the fractions. 25.5, for example, is a decimal number.

Here,

In binary, each digit represents a power of 2, starting with the rightmost digit. The rightmost digit in 11111111 represents 2^0, the second digit from the right represents 2^1, and so on. To convert a binary number to decimal, you add up the value of each digit times the corresponding power of 2.

For 11111111, the calculation would be:

=1 * 2^7 + 1 * 2^6 + 1 * 2^5 + 1 * 2^4 + 1 * 2^3 + 1 * 2^2 + 1 * 2^1 + 1 * 2^0 = 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1

Luke was solving the equation √(3-x) = -16. He was about to square

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Luke realized that squaring each side of the equation √(3-x) = -16 would lead to an extraneous solution. This happens because squaring each side of the equation changes the direction of the inequality, which may result in solutions that do not actually satisfy the original equation.

The square root of any positive number is always positive, so the left side of the equation is always non-negative. However, -16 is a negative number, so there is no real solution to the equation √(3-x) = -16.
