$\frac{12!}{5!(12-5)!}= \frac{12!}{5!7!} = \frac{12\times 11 \times 10\times 9 \times 8}{5!} = 12\times 11\times 3 \times 2 = \huge{\boxed{\bf{792}}}}$

What is the value of x?

vazorg [7]

Answer:

x = 58

Step-by-step explanation:

Angle = 1/2(difference of intercepted arcs)

51 = 1/2 ( 160 -x)

Multiply each side by 2

2*51 = 160-x

102 = 160-x

Subtract 160

102 -160 = -x

Please help. 20 points and brainliest.

Answer:

minimum -45, maximum 32

Step-by-step explanation:

C=4x-3y

x≥0, y≥4, x+y≤15

Maximum value of C can be achieved at max x and min y

min y=4 => max x=15-4=11

C=4*11-3*4= 32

Minimum value of C can be achieved at min x and max y

min x=0, max y =15

C=4*0-3*15= -45

So answer is minimum -45, maximum 32

Answer:

I believe its (- 2, 2 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is

B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
