Answer» Here we go, $\| {x}^{2} - 4x + 3 \| = - \| {x}^{2} - 5x + 4 \| \\ \frac{\| {x}^{2} - 3x - x + 3 \|}{\| {x}^{2} - 4x - x + 4\|} = - 1 \\ \frac{\| x(x - 3) - (x -3 )\|}{\|x(x - 4) - (x - 4)\| } = - 1 \\ \frac{\| (x - 1)(x - 3)\|}{\|(x - 1)(x - 4) \|} = - 1 \\ \frac{\| x - 3\|}{\|x - 4 \|} = - 1 \\ \| \frac{x - 3}{x - 4} \| = - 1$ You can SEE that it's giving a negative value which is not what happens when you USE mod on all of RHS, If you're still not satisfies use wave curvy method to get the range and you're gonna FIND there is none.

Show that the lines x-y-2=0, x + y - 4=0, x + 3y - 6 = 0 are concurrent.

Answer»

Given:

There EQUATION of line which are x-y-2=0, x + y - 4=0 and x + 3y - 6 = 0.

To Find :

PROVE that they are concurrent.

Solution:

Equation of line are:

X- Y = 2 ...1)

X + Y = 4 ...2)

X + 3Y = 6 ...3)

On adding equation 1) and equation 2), we get:

X+ X = 2 + 4

2X = 6

X = 3

On putting the value of X in equation 1):

X- Y = 2

3 - Y = 2

-Y = 2 -3

-Y = -1

Y = 1

On putting value of X and Y in L.H.S of equation 3):

X + 3Y = 6

L.H.S

X + 3 Y

3 + 3×1

3+3

6 = R.H.S

MEANS intersection of line 1 and line 2 are lie on line 3. So all three line are concurrent. Means these are intersect at a common point.

Answer» ANSWER: SOLUTION, Here,(3x+4,2x+y)=(5,4) Equating the CORRESPONDING co-ordinates we get, 3x+4=5 2x+y=4 or, 3x=1 or, 2*(1/3) + y = 4 or,x=1/3 or, y= 4-(2/3) or, y= 10/3

38.

Find x and y if (3x+4,2x+y) =(5,4)

Answer»

ANSWER:

SOLUTION,

Here,(3x+4,2x+y)=(5,4)

Equating the CORRESPONDING co-ordinates we get,

3x+4=5 2x+y=4

or, 3x=1 or, 2*(1/3) + y = 4

or,x=1/3 or, y= 4-(2/3)

or, y= 10/3

36(a+b)^2 - 16 ( a-b)^2 factorise the following

Answer»

$\huge{\underline{\underline{\red{♡Solution→}}}}$

$36( {a + b)}^{2} - 16( {a - b)}^{2}$

$( {6(a + b))}^{2} - ( {4(a - b))}^{2}$

USE the IDENTITY →

${a}^{2} - {b}^{2} = (a + b)(a - b)$

$(6(a + b) + 4(a - b))(6(a + b) - 4(a - b))$

$= (6a + 6b + 4a - 4b)(6a + 6b - 4a + 4b) \\ = (10a + 2b)(2a + 10b)$

$= 2(5a + b) \times 2(a + 5b)$

$\boxed{= 4(5a + b)(a + 5b)}$

50.	Which among these is also equivalent to one degree(1°)in angles
Answer» A degree (in FULL, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees. It is not an SI unit, as the SI unit of ANGULAR MEASURE is the radian, but it is mentioned in the SI brochure as an accepted unit.[4] Because a full rotation equals 2π RADIANS, one degree is EQUIVALENT to π/180 radians.
