Please answer it with solution

x = - 2 2/3

y =  - 4 1/3

Step-by-step explanation:

-4x -2y = - 2

4x +8y = -24

Now if you just add those 2 equations, what will happen is that the xs will cancel. They are equal but opposite in sign

6y = - 26              Now divide by 6

6y/6 = -26/6        Combine

y = - 4 2/6 = - 4 2/6

y = - 4 1/3

Now use the top equation to find x

-4x - 2(-4 1/3) = - 2

-4x +  8 2/3 = - 2                     Subtract 8 2/3 from both sides

- 4x = - 2 - 8 2/3                     Combine

- 4x = - 10 2/3                         Divide by - 4

x = - 10 2/3 / - 4

x = - 2 2/3

  (x, y) = (8/3, -13/3)

Step-by-step explanation:

The x-coefficients are opposites, so the x-terms can be eliminated simply by adding the equations.

  (-4x -2y) +(4x +8y) = (-2) +(-24)

  6y = -26

  y = -26/6 = -13/3

Substituting into the first equation gives ...

  -4x -2(-13/3) = -2

  2x -13/3 = 1 . . . . . . . . divide by -2

  2x = 16/3 . . . . . . . . . add 13/3

  x = 8/3

The solution is (x, y) = (8/3, -13/3).

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
