Introduction to prepare for advanced math solutions:

Mathematics is mainly considered as the main branches of science. Normally all the mathematical operations like addition, division, multiplication as well as subtraction are easy to do in case of simple problems. Prepare for advanced math problems solution is simple and easy. In this session, we will see how we have to prepare for advanced math solution.

Prepare for advanced math solutions:

Example problem 1- Prepare for advanced math solutions

Calculate the equation of the line using the points (5, - 5) and (4, 1) that passes through the line.

Solution:

Line passing through the points is (5, - 5) and (4, 1).

Equation of a line =?

We know that, the equation of line is y = mx + c.

m = slope, c = y-intercept.

To find the equation of line, find out the m – slope and y-intercept values.

Given points are (5,- 5) and (4, 1).

(x1, y1) is (5,- 5)

(x2, y2) is (4, 1)

Slope m = (y2 - y1)/(x2 - x1)

= (1 - (-5)) / (4 -5)

= (1 + 5) / (-1)

= 6 / (-1)

Slope m = -6

Substitute m = -6 in the equation y = mx + c.

Hence result as y = - 6x + c

To find the y-intercept, substitute any given points in the equation.

We take (x2, y2) is (4, 1) substitute in equation,

y = - 6x + c

1 = - 6 *4 + c

c = -24 -1

c = -25

y- intercept c = -25

Now substitute both the values in the equation, to get the equation of the line.

Substitute c = -25 and m = -6 in the equation as follows,

y = mx + c

y = -6x - 25

The equation of the line is y = -6x -25.

Example problem 2:

The dimension of door-frame is given as 5 × 8 meter, which is fixed on the wall of dimension 20×30 meters. Calculate the total labor charges for painting the wall. If the labor charges for painting one sq m...

...e y = 2 in the equation 4,

10y +14z = 62 ----------- (4)

10(2) + 14z = 62

20 + 14z = 62

14z = 62 – 20

14z = 42

z =

z = 3

Substitute z = 3 and y = 2 in the equation 1, we get,

2x + 4y + 6z = 28 ------- (1)

2x + 4(2) + 6(3) = 28

2x + 8 +18 = 28

2x = 28 – 18 – 8

2x = 2

x =

x = 1

Hence we have solved the equations, we get the variables x = 1, y = 2 and z = 3.

Practice problems in Prepare for advanced math solutions

Practice problem 1 – Prepare for advanced math solutions
