You solve equations algebraically by using equations to answer and having variables rather than the arithmetic way (doing the work).

Ex: instead of 20÷5=4 (arithmetic), you do

20=5x

Answer:

yes, the remainder is 6.

Step-by-step explanation:

the remainder is how many is left over if the divisor doesn't go perfectly into the dividend.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The remainder of the division $35,286 by 7 using long division is 6.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3x + 5 = 4 is an expression.

We have,

$35,286 ÷ 7

Now,

7) 35286 ( 540

  -35      

       286

     -280

            6

7 x 5 = 35

7 x 40 = 280

We see that,

Using long division,

The remainder is 6.

The dot plot for the considered data is plotted based  on how many times each observation occured (given by frequencies), as plotted in the image attached.

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

Thus, suppose if we observed the value 'x', then we will make a dot above 'x'. If there is already a dot over 'x', then we will make a new dot over that dot.

If instead of only observations, the table of unique observation and frequency is given, then we plot dots that many times as the count written in the frequency table.
Thus, if its written that the value 2 has 3 has its frequency, then we plot 3 dots one over the other above the value 2 in the horizontal axis.

For this case, we're given the unique observation to frequency table as:

Diameter (cm)          Frequency

2                                       3

2.25                                  3

2.5                                    4

2.75                                  4

3                                       2

3.5                                   2

That means, over the value 2, plot 3 dots (as diameter 2 occured 3 times), and so on, over the value 3.5, plot 2 dots.

Vertical lines

Step-by-step explanation:

Linear relations are not functions when they appear graphically are vertical lines.

" Function is defined as  when the relation between variables are such that each input has one and only one output."

According to the question,

Linear relation are defined as y = ax + b

A. Horizontal lines  is expressed by equation y = 0x + b

For each x = 0 , 1, 2, 3, .... value of y = b. For each input single output 'b' is defined.

Horizontal lines represent the function.

B. Linear relation represents straight line .

For example y = 2x +3

For each x we have single output y.

Therefore linear relation represents function.

C. Vertical lines x = k , here for x=k there are many outputs y = 0,1, 2, 3....

Vertical line does not represent function.

Hence, linear relations are not functions when they appear graphically are vertical lines.

Answer:

-6

Step-by-step explanation:

7x +4=3x-20

4x=-24

x= -6

The given problem can be translated into the equation 7x + 4 = 3x - 20. By solving this equation, we find out that the number x is -6.

In this mathematical problem, we can define the number we are looking for as x. Based on the problem, we have the equation 7x + 4 = 3x - 20. This equation comes from the problem statement that 'four more than seven times a number is the same as twenty less than three times the number'.

Next, we can solve for x by subtracting 3x from both sides to get 4x + 4 = -20. Then, to isolate x, we subtract 4 from both sides to get 4x = -24. Finally, we divide by 4 on both sides and find that x = -6, which is the solution.

Answer:

Step-by-step explanation:

No. of white bands = 15% of 360 = (15/100)*360= 54

No.of red bands = 360 - 54 = 306

No. bands remaining = 360 - 140 = 220

No. of remaining white bands = 20% of  220= (20/100)*220 = 44

No. of remaining red bands = 220 - 44 = 176

No. of red band used = No.of red bands - No of remaining bands

= 306 - 176 = 130

The force exerted on victim is 20 newton

Solution:

An attacker swings a board with a mass of 2 kg toward a victim

The acceleration is 10 [tex]m/s^2[/tex] when the board hits the victim

To find: Force exerted on victim

The force is given by formula:

[tex]F = mass \times acceleration[/tex]

From given,

[tex]mass = 2 \text{ kg }\\\\Acceleration = 10[/tex] [tex]m/s^2[/tex]

Substituting the values in formula,

[tex]Force = 2 \times 10 = 20[/tex]

Thus force exerted on victim is 20 newton

A mass of 2 kg and an acceleration of 10 m/s², the force is calculated to be 20 Newtons.

To determine the force exerted by the board on the victim, we can use Newton's second law of motion, which states:

⇒ Force (F) = Mass (m) x Acceleration (a)

Given that the mass of the board is 2 kg and the acceleration when it hits the victim is 10 m/s², we substitute these values into the equation:

⇒ F = 2 kg x 10 m/s²

⇒ F = 20 N

Thus, the board exerts a force of 20 Newtons on the victim.

Complete question:

An attacker swings a board with a mass of 2 kg toward a victim. The acceleration is 10 m/s² when the board hits the victim. How much force did the board exert on the victim?

Final answer:

To find the equation of a line perpendicular to y = -4x + 1 that passes through the point (-7, 1), determine the slope, use the point-slope form, and convert it to slope-intercept form.

Explanation:

To find the equation of a line perpendicular to y = -4x + 1 that passes through the point (-7, 1), we first determine the slope of the perpendicular line. The slope of a line perpendicular to a line with slope m is the negative reciprocal of m. So, the slope is 1/4. Next, we use the point-slope form of a line y - y₁ = m(x - x₁) and plug in the point to find the equation in slope-intercept form, y = mx + b.

Plugging in (-7, 1) and slope 1/4 into the point-slope form, we get y - 1 = (1/4)(x + 7). Simplifying gives us y = (1/4)x + 2. Hence, the equation of the line perpendicular to y = -4x + 1 that passes through the point (-7, 1) is y = (1/4)x + 2.
