Equations in Iwo V Solve the system by the addition method. 3x+8y=6 3x-8y=6 Select the correct choice below and, if necessary, f
sweet [91]

Answer:

A. there is exactly one solution. the solution set is {(2, 0)}.

Step-by-step explanation:

3x + 8y = 6

3x - 8y = 6

when we add these 2 equations, we get

6x + 0 = 12

6x = 12

x = 2

now we use one of the original equations to get y :

3×2 + 8y = 6

6 + 8y = 6

8y = 0

y = 0

PLEASE HELP
Ronch [10]

Answer:

<em><u>1 and 5</u></em>

Step-by-step explanation:

The squares have a side length of 10 and 1 square side is the radius of the half-circles. Since there are two half-circles, find the circumference for one full circle:

C=2\pi r

Insert the radius:

r=10\\C=2\pi *10

Simplify pi:

C=2*3.14*10

Simplify multiplication:

C=6.28*10\\C=62.8

The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:

P=10+10+10+10\\P=10+10+20\\P=10+30\\P=40

Add the perimeter of the circle and the square together:

P=62.8+40=102.8

Now see which of the options gives you the perimeter:

1. 40+20\pi =102.8  ****

2. unavailable

3. 120+20\pi =182.8

4. 300+100\pi =614.2

5. 10+10+10\pi +10+10+10\pi =102.8 ****

Finito.
