9353.	Solve for x: 2x – y = (3/4)x + 6.????
Answer» Answer: 2x – y = (3/4)X + 6. or, 2x - (3/4)x = y + 6. or, (8X -3x)/4 = y + 6. or, 5X/4 = y + 6. or, 5x = 4(y + 6). or, 5x = 4y + 24. or, x = (4y + 24)/5. Therefore, x = 4(y + 6)/5

9353.

Solve for x: 2x – y = (3/4)x + 6.????

Answer»

Answer:

2x – y = (3/4)X + 6.

or, 2x - (3/4)x = y + 6.

or, (8X -3x)/4 = y + 6.

or, 5X/4 = y + 6.

or, 5x = 4(y + 6).

or, 5x = 4y + 24.

or, x = (4y + 24)/5.

Therefore, x = 4(y + 6)/5

9379.

Find the quadratic equation whose roots is (3±i√5)/2

Answer»

$\large\underline{\sf{Solution-}}$

Given that roots of the QUADRATIC equation are

$\rm :\longmapsto\:\dfrac{3 + \sqrt{5} i}{2}$

and

$\rm :\longmapsto\:\dfrac{3 - \sqrt{5} i}{2}$

Let assume that,

$\rm :\longmapsto\: \alpha = \dfrac{3 + \sqrt{5} i}{2}$

and

$\rm :\longmapsto\: \beta = \dfrac{3 - \sqrt{5} i}{2}$

Now, Consider

$\red{\rm :\longmapsto\: \alpha + \beta }$

$\rm \: = \: \: \dfrac{3 + \sqrt{5} i}{2} + \dfrac{3 - \sqrt{5} i}{2}$

$\rm \: = \: \: \dfrac{3 + \sqrt{5} i + 3 - \sqrt{5}i }{2}$

$\rm \: = \: \: \dfrac{6}{2}$

$\rm \: = \: \: 3$

$\bf\implies \: \alpha + \beta = 3$

Now, Consider

$\red{\rm :\longmapsto\: \alpha \beta }$

$\rm \: = \: \: \dfrac{3 + \sqrt{5} i}{2} \: \: \times \: \: \dfrac{3 - \sqrt{5} i}{2}$

We know,

$\boxed{ \rm{ (x + y)(x - y) = {x}^{2} - {y}^{2}}}$

So, using this identity, we get

$\rm \: = \: \: \dfrac{ {3}^{2} - (\sqrt{5} i) {}^{2} }{4}$

$\rm \: = \: \: \dfrac{9 - 5 {i}^{2} }{4}$

$\rm \: = \: \: \dfrac{9 + 5}{4} \: \: \: \: \: \: \: \: \: \{ \because \: {i}^{2} = - \: 1 \}$

$\rm \: = \: \: \dfrac{14}{4}$

$\rm \: = \: \: \dfrac{7}{2}$

$\bf\implies \: \alpha \beta \: = \: \: \dfrac{7}{2}$

Now, Required Quadratic equation is given by,

$\red{\rm :\longmapsto\: {x}^{2} - ( \alpha + \beta ) + \alpha \beta = 0}$

On SUBSTITUTING the VALUES, we have

$\rm :\longmapsto\: {x}^{2} - 3x + \dfrac{7}{2} = 0$

can be REWRITTEN as

$\rm :\longmapsto\: {2x}^{2} - 6x + 7 = 0$

Additional Information :-

Nature of roots :-

Let us consider a quadratic equation ax² + bx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.

If Discriminant, D > 0, then roots of the equation are real and unequal.

If Discriminant, D = 0, then roots of the equation are real and equal.

If Discriminant, D < 0, then roots of the equation are unreal or complex or imaginary.

Where,

Discriminant, D = b² - 4ac

Solution set of the inequation given by -11≤4x-3≤13 is: * (-2,4) [-11,13] [-2,4] [-8,16]

Answer»

SOLUTION

TO CHOOSE THE CORRECT OPTION

Solution set of the inequation given by

- 11 ≤ 4x - 3 ≤ 13 is:

(-2,4)

[-11,13]

[-2,4]

[-8,16]

EVALUATION

Here the given inequality is

$\sf{ - 11 \leqslant 4x - 3 \leqslant 13}$

Now

$\sf{ - 11 \leqslant 4x - 3 \: \: \: gives}$

$\sf{ \implies \: - 11 + 3 \leqslant 4x }$

$\sf{ \implies \: 4x \geqslant - 8 }$

$\sf{ \implies \: <klux>X</klux> \geqslant -2 }$

Again

$\sf{ \: 4x - 3 \leqslant 13 \: \: \: gives }$

$\sf{ \implies \: 4x \leqslant 13 + 3}$

$\sf{ \implies \: 4x \leqslant 16}$

$\sf{ \implies \: x \leqslant 4}$

COMBINING we get

- 2 ≤ x ≤ 4

Hence the required solution set is [ - 2 , 4 ]

FINAL ANSWER

Hence the correct option is [ - 2 , 4 ]

Answer»

Answer:

Q7:

Given the polynomial is :

$3 {x}^{2} - kx + 6$

and sum of ZEROS is = 3

we KNOW that,

$\sf \: if \: a {x}^{2} + bx + c \: \: is \: a \: quadratic \\ \: polynomial \: \:and \: \alpha \: and \: \beta \: \: are \\ the \: zeroes \: \: \: then \: \\ \\ \sf \: \: sum \: of \: zeroes \: \: \: \alpha + \beta = - \frac{b}{a}$

In the question,

$\sf \: \alpha + \beta = 3 \\ \sf \: according \: to \: the \: question \: \\ \sf \: \: \: \: \: \: \: \: \: \alpha + \beta = - \frac{ - k}{3} = \frac{k}{3} \\ \sf \implies \: 3 = \frac{k}{3} \\ \sf \implies \: k = 3 \times 3 \\ \sf \therefore \: k = 9$

Q8:

Answer:

No.

Explanation :

We have $<klux>4</klux>^n$ , where n is a natural number.

so, n= 1,2,3,4...

$\sf \: if \: n = 1 \: \: then \: {4}^{1} = 4 \\ \sf \: if \: n = 2 \: \: then \: {4}^{2} = 16 \: \: \: and \: so \: on \:$

Again, if a number ends with zero then it is divisible by 5

Here, 4, 16 are not dividible by 5.

Therefore, $4^n$ can NEVER end with zero.

Hence proved.

= w³ ( 16 - U⁴ )

= w³ ( 4² - (u²)²)

= w³ ( 4+u² ) ( 4 - u² )

In the question: ⇒ √(x - 1)² + (y - 5)² = √(x - 5)² + (y - 1)² ⇒ (x² + 1 - 2x) + (y² + 25 - 10Y) = (x² + 25 - 10x) + (y² + 1 - 2y) ⇒ -2x - 10y = -10x - 2y ⇒ 10x - 2x = 10y - 2y ⇒ 8X = 8y ⇒ x = y proved

Using distance formula, distance b/w POINTS (x₁, y₁) , (x₂, y₂) is GIVEN by √(x₁ - x₂)² + (y₁ - y₂)². In the question:

⇒ √(x - 1)² + (y - 5)² = √(x - 5)² + (y - 1)²

⇒ (x² + 1 - 2x) + (y² + 25 - 10Y) = (x² + 25 - 10x) + (y² + 1 - 2y)

Answer»

Step-by-step explanation:

you have to divide x³-2x²-12x+16 by x-4

the QUOTIENT will be the number of candies.

but MAKE sure that the REMAINDER is zero.

by remainder theorem

let p(x)=x³-2x²-12x+16

x-4=0

x=4

p(4)= (4)³-2(4)²-12(4)+16

=64-32-48+16

=32-32=0

hence the remainder is zero.

now you can divide p(x) by x-4 and the quotient is the number of candies.

2x – y = (3/4)X + 6.

or, 2x - (3/4)x = y + 6.

or, (8X -3x)/4 = y + 6.

or, 5X/4 = y + 6.

or, 5x = 4(y + 6).

or, 5x = 4y + 24.
