Answer:

If the line doesn't pass through the origin, the easiest point to pick is the origin (0,0). Substitute into your inequality.

y > 5x + 1

0 > 5(0) + 1

0 > 1 which is a false statement.

So, you shade the side of the line on which (0,0) doesn't lie.

If the statement would have be true, you shade the side of the line on which (0,0) lies.

Answer:

Step-by-step explanation:

Hint: 1- 2sin²x = Cos 2x

LHS = 1 - 2Sin² (π/4 - Ф/2)

= Cos 2 *(π/4 - Ф/2)

= Cos 2*π/4 - 2*Ф/2

= Cos π/2 - Ф

= Sin Ф = RHS

Answer:

14) 4x+10=8x-26 (corresponding angles are equal)

4x-8x=-26-10

-4x=-36

x= -36/-4= 9

x=9

15) perimeter of rectangle= 2(l+b)

2( l+ $\frac{2l}{3}$ ) = 40m

2l+ $\frac{4l}{3}$ =40

Take LCM as 3

$\frac{2l}{1}$ * $\frac{3}{3}$ + $\frac{4l}{3}$ =40

$\frac{6l+4l}{3}$ = 40

$\frac{10l}{3}$ = 40

10l=40*3

10l = 120

l= 120/10 =12 cm

l=12cm

b= 2/3 *12 = 8cm

16) 2:3:4

It can be written as 2x+3x+4x

sum of angles of a triangle =180 degree

so 2x+3x+4x=180

9x=180

x=180/9=20 degree

1st angle=2x=2*20= 40 degree

2nd angle= 3x=3*20 =60 degree

3rd angle= 4x=4*20= 80 degree

17) sum of interior angles of a pentagon is 540 degree

so, 125+88+128+60+x=540 degree

401 +x= 540 degree

x=540-401= 139 degree

leonid [27]

Answer: There are 13 gamblers who played exactly two games.

Step-by-step explanation:

Since we have given that

Number of gamblers played black jack, roulette and poker = 5

Number of gamblers played roulette and poker = 8

Number of gamblers played black jack and roulette = 11

Number of gamblers played only poker = 12

Number of gamblers played poker = 24

Number of gamblers who played only roulette and poker is given by

$8-5=3$

Number of gamblers who played only black jack and roulette is given by

$11-5=6$

Number of gamblers who played only poker and black jack is given by

$24-(12+3+5)\\\\=24-20\\\\=4$

So, the number of gamblers who played exactly two games is given by

$3+6+4=13$

Hence, there are 13 gamblers who played exactly two games.
