Multiplication Consider this system:
Which of the following operations would eliminate the x-terms if the two equations were added together afterward?

Multiply the first equation by –6.
Multiply the first equation by –2.

Multiply the first equation by 2.

Multiply the first equation by 6.
Which of the following operations would eliminate the y-terms if the two equations were added together afterward?

Multiply the first equation by -2.
Multiply the first equation by 2.

Multiply the second equation by -2.

Multiply the second equation by 2.
Use elimination to solve the system. The solution is ?

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.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
