(2x/3)-(7x/15)=2(10x-7x)/15=23x=30

x=10

Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.

Hi,

Here is the answer to your question.

10.5-0.3 of (4)+2.8*4.410.5-1.2+12.3221.62

21.62 is the most correct answer

hope it helps u

Given:x²-3x+2 is a factor of x⁴-px²+q=0

To prove:p=5; q=4

Solution:x²-3x+2=0sum=-3; product=2number=-2,-1x²-2x-x+2=0x(x-2)-1(x-2)=0(x-1)(x-2)=0x=1,2

p(x) =x⁴-px²+qp(1)=1-p+q0=1-p+qp-q=1...(1)

p(2)=16-4p+q4p-q=16...(2)solving (1)&(2)

-3p=-15p=5substituting p=5in (1)

5-1=qq=4

Thus p=5; q=4

5x-4y+8=07x+6y-9=0a1/a2=5/7b1/b2=-4/6=-2/3since a1/a2 is not equal to b1/b2, then the solution is unique.that is the lines do not coincide, it intersect

Formulate using direct proportion with percentages.

25 percent less is 1-0.25

A = (1 - 0.25)B

B = A/0.75

B = 4/3 A

So B's income is 100.33% percent of A's income

Ans. Population in 2006 = 19000

Population in 2007 = 22000

Change in Population = 22000-19000 = 3000

% change =( change in population * 100)/ population in 2006

=> 3000 *100/19000 = 300/19 = 15.78%

Increase is 48400-40000=8400hence percent increase is 8400/40000*100=21%

-35900933 is the answer

the answer is -35900933

-35900933 is the correct answer of the given question

Let the number be x,

(x-1/2)1/2=1/8

so we need to solve this,

2x-1/2 * 1/2 = 1/8

2x-1/2=1/8*2/1=1/4

2x-1/2=1/4

so, 2x=1/4+1/2=6/8=3/4

hence, 2x=3/4,

so,x=3/8

Now, AB ll CD, since by construction, EF ll AB ⇒ EF ll CDConsider the ΔADC,EO ll DCThus, by Basic proportionality theorem, (AE / ED) = (AO / OC) .... (i)Now, consider Δ ABD, EO ll AB,Thus, by Basic proportionality theorem, (AE / ED) = (BO / OD) .... (ii)From (i) and (ii), we have, (AO / OC) = (BO / OD) (since L.H.S of i and ii are equal)Hence we proved that, (AO / OC) = (BO / OD)

Answer will be 13/12

The correct answer is 13/12

Ans - 13/12 1/3 * 13/4 = 13/12

13/12 is correct ans

13/12 is the right answer of the following

Given.ABCD is a parallelogram.A point E is taken on the side BC.AE and DC are produced to meet at M.Prove that ar(∆ADM)=ar(∆ADM).....(1)

As DC||AB,soCM||AB

Since triangles on the same base and between the same parallels are equal in area,so we have ar(∆ACM)=ar(∆BCM).....(2)Adding(1) and (2),we getar(∆ADC)+ar(∆ACM)=ar(∆ABC)+ar(∆BCM)=ar(∆ADM)=ar(ABMC). Hence proved.

Area of shaded region= area of square - areaof 4 quadrants12*12-(4*1/4*π*6*6)as radius = 12/2= 6144-(36π}

Yes this point will lie on the line because when we put value of x & y then lhs and rhs become equal.

yes ,put values of x and y as 3,-2 respectively in equation

2x-3y=12putting x= 3, y= -22×3-3(-2)6+6=12yes (3,-2) lie on line 2x-3y=12

yes by putting values of x and y as 3,-2 in the equation

2x-3y=1

Yes the point lie on the line

12 centimeter is the best answer

12 cm is breadth of rectanle

(3,1) lies on equation that means it satisfies the equation by putting ordered pair value we can find the value of k.2(3)+3(1)-k=06+3-k=0k=9

Thnk u

Put 3 and a as the values of x and y in the equation. Because the point lies on the line as given in the question.

You'll get.

2*3 - 3*a = 5

6 - 3a = 5

3a = 1

a = 1/3

A=1/3
