1:       2x+y=3
         5x-2y=12

2:      Multiply the first equation by 2
         (2) (2x+y=3) => 4x+2y=6

3:      Add
         4x+2y=6
    +   5x-2y=12
______________
         9x=18               The y's cancel out
         9x/9=18/9         The 9's cancel out
         x=2

4:     Plug (x=2) back into either equation but, I'm going to do the first one. It's  easier.
         2(2)+y=3
             4+y=3
          4-4+y=3-4         The 4's cancel out
                y=-1
Answer: (12,-1)
If you plug (x) and (y) back in it will equal 3 for the first and 12 for the second.

egoroff_w [7]

Answer:

15 years

Step-by-step explanation:

$10,312.50-$7500 = $2,812.50 in interest we need over time

7500 x 2.5= $187.50/year (interest)

$2,812.50 / $187.50 = 15 years

Examine the diagram, where BD¯¯¯¯¯¯¯¯
Sidana [21]

The value of x based on the tangent-secant theorem is: <u> 19.</u>

<em><u>Recall</u></em>:

  • The secant-tangent theorem states that when a tangent and a secant meet outside a circle, the product of the secant length and it's segment outside the circle is equal to the square of the tangent segment length.

  • Applying the tangent-secant theorem or rule, we will have this equation:

AB \times EB= DB^{2}

AB = (x-7)+4 = x -3

EB = 4

  • Substitute:

(x - 3)(4) = 8^{2} \\\\4x - 12 = 64\\\\

  • Add 12 to both sides

4x = 64 +12\\\\4x = 76

  • Divide both sides by 4

x = 19

Therefore the <u>value of x is 19.</u>
