Find the nature of the solution of the equation2xsq+x-4=7

Answer»

Step-by-step explanation:

2x² +X -4 =7

2x² + x -3=0

2x² +( 3-2)x -3=0

2x² +3X -2x -3=0

x ( 2 x +3) -1( 2x+3) =0

( x -1) ( 2x+3) =0

NumbersFind a number whose double is 45 greater than its half.Find a number such that when 5 is subtracted from 5 times the num.

Answer»

Answer:

(i) Let the number be x.

Double of x is 45 greater than its half (x/2).

We can frame the equation as

$2 \times x = 45+ \frac{x}{2}$

TRANSPOSE variables to one side, and constants to ANOTHER side.

$2x-\frac{x}{2} =45$

$\frac{3x}{2} = 45$

Transpose $\frac{3}{2}$ to the RHS.

$x=\frac{2 \times 45}{3}$

$x=30$

(II) the second QUESTION is incomplete.

The question is: 5 is subtracted from 5 times the number, the result is 4 more than twice the number.

Let the number be x.

When 5 is subtracted from 5 times x, the result is 4 more than twice x.

We can frame the equation as:

5x-5=4+2x

Transpose variables to one side, constants to another side.

5x-2x=4+5

Answer» Step-by-step EXPLANATION: Area of the ΔABC will be : \frac{1}{2} 2 1 \| 5 3 -1 \| \| 3 -2 1 \| \| 2 -1 1 \| = \frac{1}{2} 2 1 \| ( 5 [(-2)(1) - (1)(-1)] - 3 [(3)(1) - (1)(2)] + (-1) [(3)(-1) - (-2)(2)] ) \| = \frac{1}{2} 2 1 \| (5(-2+1) - 3(3-2) -1(-3+4)) \| = \frac{1}{2} 2 1 \| ( -5 - 3 +1 ) \| = \frac{1}{2} 2 1 \| -7 \| = \frac{7}{2} 2 7 Therefore, area of the ΔABC is \frac{7}{2} 2 7 sq. units. Then, the area of the remaining portion, i.e, Area of the ΔPAC = Area of the quadrilateral - Area of the ΔABC = 10 - (7/2) = \frac{13}{2} 2 13 sq. units Now, to find the locus of P(x,y), equate the area of triangle PAC fomat to its area \frac{13}{2} 2 13 sq. units. \| x y 1 \| \frac{1}{2} 2 1 \| 5 3 1 \| = \frac{13}{2} 2 13 \| 2 -1 1 \| ⇒ \frac{1}{2} 2 1 \| ( x [(3)(1) - (1)(-1)] - y [(5)(1) - (1)(2)] + (1) [(5)(-1) - (3)(2)] ) \| = \frac{13}{2} 2 13 ⇒ \frac{1}{2} 2 1 \| x(3+1) - y(5-2) + 1(-5-6) \| = \frac{13}{2} 2 13 ⇒ \frac{1}{2} 2 1 \| 4x - 3y -11 \| = \frac{13}{2} 2 13 Cancelling \frac{1}{2} 2 1 on both sides, we get : ⇒ \| 4x - 3y -11 \| = 13 ⇒ 4x - 3y -11 = ± 13 So, the equations are 4x - 3y -11 = + 13 and 4x - 3y -11 = - 13, and the locus will be : ⇒ ( 4x - 3y -11 )² = (+13)(-13) ⇒ 16x² + 9y² + 2(4x)(-3y) + 2(4x)(-11) + 2(-3y)(-11) + (-11)² = -169 ⇒ 16x² + 9y² - 24xy - 88x + 66y + 121 + 169 = 0 ∴ 16x² + 9y² - 24xy - 88x + 66y + 290 = 0 Therefore, the locus of point P(x,y) is 16x² + 9y² - 24xy - 88x

| (5(-2+1) - 3(3-2) -1(-3+4)) |

| x(3+1) - y(5-2) + 1(-5-6) | = \frac{13}{2}

2

13

⇒ \frac{1}{2}

2

1

| 4x - 3y -11 | = \frac{13}{2}

2

13

Cancelling \frac{1}{2}

2

1

on both sides, we get :

⇒ | 4x - 3y -11 | = 13

⇒ 4x - 3y -11 = ± 13

So, the equations are 4x - 3y -11 = + 13 and 4x - 3y -11 = - 13, and the locus will be :

⇒ ( 4x - 3y -11 )² = (+13)(-13)

⇒ 16x² + 9y² + 2(4x)(-3y) + 2(4x)(-11) + 2(-3y)(-11) + (-11)² = -169

⇒ 16x² + 9y² - 24xy - 88x + 66y + 121 + 169 = 0

∴ 16x² + 9y² - 24xy - 88x + 66y + 290 = 0

Therefore, the locus of point P(x,y) is

16x² + 9y² - 24xy - 88x

Answer» Given: At the rate of * 3/- per m², cost of PAINTING a rectangular floor is Rs. 7,056/- To find: The length of the floor Solution: LET's assume, "l" → the length of the rectangular floor "b" → the breadth of the rectangular floor It is given that the breadth is 75% of its length, so we can form an eq. as: b = $\frac{75}{100} \times l$ $\implies b = \frac{3}{4} \times l$ ...... (i) We know that, The cost of painting the rectangular floor = Rs. 7056 ⇒ [Area of the rectangular floor] × [rate per meter square] = Rs. 7056 ⇒ [l × b] × 3 = 7056 substituting the value of b from (i), we get ⇒ $[l \times \frac{3}{4}\times l ] \times 3 = 7056$ ⇒ $l^2 \times \frac{9}{4} = 7056$ ⇒ $l^2 = \frac{7056 \times 4}{9}$ ⇒ $l^2 = 3136$ ⇒ $l = \sqrt{3136}$ ⇒ $\bold{l = 56\:m}$ Thus, the length of the floor is → *56 m. ------------------------------------------------------------------------------------------* ALSO View: find the cost of painting the walls of a room at rupees 25 per square metre if Length breadth and height of a room has 6 m, 4 m and 2.5 M respectively brainly.in/question/7931183 a rectangular room is of length 10m, breadth 6m , height 3m. the four walls and the roof have to be painted. if the cost of painting is 75/- per square metre, what will be the total cost? the area of the windows and doors is 6 SQ.m , which are not to be painted. brainly.in/question/1982836 Find the cost of painting a tank of dimension 3m×2m×1.5m at rupees 20 per square metre brainly.in/question/2084952 Find the cost of painting the walls of a room if the room is 4m 50cm high and each side of the room is 6m LONG .The cost of painting is Rs10per Sq metre? brainly.in/question/2252685

At the rate of * 3/- per m², cost ofpainting a rectangular floor is* 7,056/-. If the breadth of the flooris 75% of its length, then what is thelength of the floor ?

Answer»

Given:

At the rate of * 3/- per m², cost of PAINTING a rectangular floor is Rs. 7,056/-

To find:

The length of the floor

Solution:

LET's assume,

"l" → the length of the rectangular floor

"b" → the breadth of the rectangular floor

It is given that the breadth is 75% of its length, so we can form an eq. as:

b = $\frac{75}{100} \times l$

$\implies b = \frac{3}{4} \times l$ ...... (i)

We know that,

The cost of painting the rectangular floor = Rs. 7056

⇒ [Area of the rectangular floor] × [rate per meter square] = Rs. 7056

⇒ [l × b] × 3 = 7056

substituting the value of b from (i), we get

⇒ $[l \times \frac{3}{4}\times l ] \times 3 = 7056$

⇒ $l^2 \times \frac{9}{4} = 7056$

⇒ $l^2 = \frac{7056 \times 4}{9}$

⇒ $l^2 = 3136$

⇒ $l = \sqrt{3136}$

⇒ $\bold{l = 56\:m}$

Thus, the length of the floor is → 56 m.
