w = 0  and z= -2  are the value in linear equation.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                    Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

3w-4z= 8

2w+3z=-6

multiply both sides of the equation of a

  6w - 8z = 16

    3(2w +3z ) = - 6 * 3

calculate the quotient

         6w - 8z = 16

        3(2w +3z ) = - 6 * 3

    6w - 8z = 16

    6z + 3z = -18

substract the two equation

                  6w - 8z - (  6z + 3z) = 16 - (-18)

                            -17z = 34

                               z = -34/17

                                 z = - 2

put the value of z in equation

           6w - 8 * -2  = 16

          6w + 16  = 16

               6w = 0

Step-by-step explanation:

The line of best fit to represent the given data would be y = 13.5x + 10.

What is the best-fit line in statistics?

A best-fit line, also known as a line of best fit, is a straight line that is used to model the relationship between two variables in a set of data.

A line of best fit is a straight line that is the best approximation of the data points. To find a line of best fit, you can use the method of least squares, which involves minimizing the sum of the squared differences between the data points and the line.

Given the data (x,y) = {(0,10), (1,12), (2,15), (3,20), (4,30)}, the slope of the line can be calculated using the formula:

slope = (NΣ(xy) - Σx * Σy) / (NΣ(x^2) - (Σx)^2)

Where N is the number of data points.

Plugging in the data:

slope = (5*(10+24+30+60+120) - (0+1+2+3+4)(10+12+15+20+30)) / (5(0+1+4+9+16) - (0+1+2+3+4)^2)

slope = 270/20 = 13.5

y-intercept can be calculated using the formula:

y-intercept = (Σy - slopeΣx)/N

y-intercept = (10+12+15+20+30 - 13.5(0+1+2+3+4))/5

y-intercept = 10

So, the equation of the line of best fit would be:

y = 13.5x + 10

This equation represents a line with a slope of 13.5 and a y-intercept of 10. This line of best fit can be used to make predictions about the ticket price for a given number of years since 1980.

Hence, the line of best fit to represent the given data would be y = 13.5x + 10.

Frequencies are arranged into visual displays known as frequency distributions in order to make the information more understandable. Absolute or relative frequencies, such as ratios or percentages, can be shown in a frequency distribution. A frequency distribution can be shown using a graph or a frequency table. In a frequency distribution, the precise number of observations and the percentage of observations falling inside each range may both be shown. The distribution in the latter case is known as a relative frequency distribution. An observation's frequency is the frequency with which it appears in the data.

Around 100 hours will take for both vats to contain the same amount of liquid.

How do you calculate the rate of evaporation of a liquid?

The equation indicates that the evaporation rate,

W = (95+0.425*V)*(Pw-Pa)/Y, where W is the evaporation rate, V is the air velocity at the water surface,  Pw is the saturation vapor pressure at water temperature.

To find out how many hours it will take for both vats to contain the same amount of liquid, we need to compare the rates at which the liquid is evaporating from each vat.

We can set up the following equation:

(35 - x) / 0.25 = (40 - x) / 0.35

where x is the amount of liquid in both vats at the time they reach the same level.

We can then solve for x by multiplying both sides by 0.25 and 0.35 and then subtracting one equation from the other:

35 - x = 40 - x

x = 5

So, both vats will contain 5 liters of liquid at the time they reach the same level.

To find out how many hours it will take to reach this point, we can use the rate of evaporation for either vat.

For Vat A:

35 - 5 = 30 liters

30 liters / 0.25 liters/hour = 120 hours

For Vat B:

40 - 5 = 35 liters

35 liters / 0.35 liters/hour = 100 hours

So, It will take around 100 hours for both vats to contain the same amount of liquid.

Answer: Let one of the number be X and the other no will be x +18, this is as per given sum.

By sum,

Step-by-step explanation: x + x + 18 = 128

or, 2 x = 128 - 18 = 110

Therefore x = 55 & the other no will be 55 + 18 = 73

Hence, 55 & 73 are the two numbers.

The remainder when the function f(x) = x⁴ + 2x³ + 4x² + x - 1 is divided by (x - 2) to get x³ + 4x² + 12x + 25 is 49. Therefore f(2) = 49

An equation is used to show the relationship between numbers and variables.

Polynomial is an expression composed of variables, constants and exponents using mathematical operations such as addition, subtraction, multiplication and division.

The remainder theorem states that when a polynomial f(x) is divided by (x - a), it gives a remainder equal to f(a).

Given that f(x) = x⁴ + 2x³ + 4x² + x - 1 is divided by (x - 2) to get x³ + 4x² + 12x + 25 with a remainder of 49

The solution is

a) The equation of line that has infinitely many solutions is y = ( -3/4 )x + 4

b) The equation of line passing through the point ( 0,1 ) is y = ( -3/4 )x + 1

c) The equation of line passing through (0,2) is y = ( -1/4 )x + 2

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

a)

Let the first point be P ( 0,4 )

Let the second point be Q ( 4 ,1 )

Now , the slope of the line passing through the points is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = -3/4

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 4 = ( -3/4 ) ( x - 0 )

y = ( -3/4 )x + 4
