Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 To eliminate y, the LCM is 2. Which of the following
Tresset [83]
Next time, please share your system of linear equations by typing only one equation per line:

<span>3x - 2y - 7 = 0 5x + y - 3 = 0  NO

</span><span>3x - 2y - 7 = 0
5x + y - 3 = 0                          YES

Mult. the 2nd equation by 2 so as to obtain 2y, which will be cancelled out by  - 2y in the first equation:

</span><span>  3x - 2y - 7 = 0
2(5x + y - 3 = 0)

Then:

  3x - 2y - 7 = 0
10x +2y - 6 = 0
----------------------
13x - 13 = 0, so that x = 1.  Find y by subbing 1 for x in either of the 2 given equations.</span>

Calculate the surface area of the figure below.
valentinak56 [21]

Answer:

a. 1,275.49 m²

Step-by-step explanation:

SA = 2πr² + 2πrh

SA = 2π(7)² + 2π(7)(22)

SA = 98π + 308π

SA = 406π

SA ≈ 1,275.49 m²

Solve this system of equations using the elimination method.
Ray Of Light [21]

Answer:

(6, -9)

Step-by-step explanation:

Our system of linear equations is:

6x + 2y = 18

-4x - 2y = -6

When we solve by elimination, we're essentially "eliminating" a variable so that we can solve for other more easily. Here, let's eliminate the y variable by adding the two equations together:

    6x + 2y = 18

+   -4x - 2y = -6

____________

    2x  +  0y = 12

x = 12/2 = 6

Plug this back into one of the original equations to find y:

-4x - 2y = -6

-4 * 6 - 2y = -6

-24 - 2y = -6

-2y = 18

y = -9

The solution is (6, -9).
