Mathematics

PilotLPTM [1.2K]3 years ago

If the line passes through the points A(x_1,y_1) and B(x_2,y_2), then the slope of the line can be determined as

m=\dfrac{y_2-y_1}{x_2-x_1}.

Then the equation of the line is

y=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)+y_1.

Answer: correct choice is B

<u>Answer:</u>

The correct answer option is m=\frac{y_2-y_1}{x_2-x_1}.

<u>Step-by-step explanation:</u>

To the find of the slope of a line, we need at least two points that are on the line: (x1,y_1) and (y_1,y_2).

With the help of the coordinates of these two points, we can find the slope of the line by taking the ratio of the difference in values of y by the difference in values of x.

The slope of a line is denoted by m:

m=\frac{y_2-y_1}{x_2-x_1}

Find the length of the missing side in the figure below. a = _______ cm.
WITCHER [35]

Answer:

\frac{2 \sqrt{177} }{5}

or

5.32cm correct to 2 decimal places

Step-by-step explanation:

This is a right angled triangle from what I know so we have to apply pythagoras theorem.

{7.1}^{2}  =  {a}^{2}  +  {4.7}^{2}

we need to rearrange this to find a²

{a}^{2}  =  {7.1}^{2}  -  {4.7}^{2}

a =  \sqrt{ \frac{708}{25} }

This can either be written as a fraction or decimal.

a =  \frac{2 \sqrt{177} }{5}

OR

a = 5.32

correct to 2 decimal places

Drag the tiles to the correct boxes to complete the pairs.
GenaCL600 [577]

The values have being matched to the variables that they represent here:

  • x-variable: the number of hours Sam works at the airport
  • y variable:  the amount in dollars that Sam has after paying back Daniel
  • 12: amount in dollars that Sam earns per hour.
  • 40: the amount in dollars Sam owes Daniel

<h3>How to solve for the equation.</h3>

The equation of this form y = 12x-40

The variable y has been said to be the amount sam has after Daniel has been paid.

X is the amount that has to be multiplied by what he earns in dollars by the hour.

40 dollars is the amount that he owes which is going to be subtracted from what he earns by the hour.
