The coefficients corresponding to k=0,1,2, ...,6 in the expansion of (x + y)^6 are ___. A. 0, 1, 6, 15, 15, 6, 1, 0

B. 1, 6, 15, 20, 15, 6, 1

C. 0, 6, 15, 20, 15, 6, 0

D. 1, 6, 15, 15, 6, 1

y > 1/3x

y < = -x + 4

hope this : )

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
