Use the substitution method to solve the system of equations

Sergeeva-Olga [200]

Answer:

x=1/4

y = -2

(1/4, -2)

Step-by-step explanation:

4x -y =3

y =-8x

substitute y =-8x into the first equation. Everywhere you see y put 8x

4x -y =3

4x - (-8x) =3

4x+8x=3

combine like terms

12x = 3

divide by 12

12x/12x = 3 /12

x = 1/4

now we need to find y

y = -8x

y = -8 * 1/4

y = -2

A lighthouse beacon can be seen 17mi in all directions. To the nearest square mile, what is the area over which the beacon can b

Alchen [17]

Imagine this as a circle. The circle will have a radius of 17mi and the lighthouse will be in the middle. The area of the circle will be the area over which the beacon can be seen.

$A=\pi r^{2}$ is the equation for the area of the circle where A is the area.

Now we simply plug in our information

A= $\pi (17)^{2}$
A=907.9 $mi^{2}$
