PLEASE HELP!!!PLEASE HELP!!!PLEASE HELP!!!PLEASE HELP!!!PLEASE HELP!!!
Dominik [7]

Answer:

The one at the bottom

Step-by-step explanation:

Plug in the value of x = 3 for every equation

I plugged the value of 3 into this equation:

2(3) +3y = 0

3 + 2y = -1

Let's start with the first line

6 + 3y = 0

-6 -6

3y = -6

3y/3 = -6/3

y = -2

Now let's solve the second line

3 +2y = -1

-3 -3

2y = -4

2y/2 = -4/2

y=-2

Since both equations have the solution y = -2, that means the system of equations is valid when the value of x is 3.

If triangle ABC=triangle DEC, and angle b=3x and angle e=6x-39, what is x
allsm [11]
If angle b and angle e are the same, I guess you can write b=e ?
So you’ll have :
3x = 6x - 39
0 = 6x - 3x - 39
39 = 3x
x = 39/3
x = 13

In circle E with m \angle DEF= 70m∠DEF=70 and DE=13DE=13 units find area of sector DEF. Round to the nearest hundredth.
Anuta_ua [19.1K]

Answer:

103.18units³

Step-by-step explanation:

Area of the sector DEF = theta/360 * πr²

r is the radius

theta is the angle subtended at the centre

theta =70 degrees

radius DE = 13units

Substitute

Area of the sector = 70/360 * 3.14(13)²

Area of the sector = 7/36 * 530.66

Area of the sector = 3,714.62/36

Area of the sector = 103.18units³ (to the nearest hundredth)
