Answer:

  (x, y) = (2, 1)

Step-by-step explanation:

Use the second equation to write an expression for x:

  x = 1 +y

Substitute that into the first equation:

  (1 +y) +4y = 6

  5y = 5 . . . . . . . . subtract 1, collect terms

  y = 1 . . . . . . . divide by 5

  x = 1 +1 = 2 . . . use the expression for x to find x from y

The solution is (x, y) = (2, 1).

I need help! can anybody help?​
Alexandra [31]

Answer:

i, m, and then k (use my method to do the other one)

Step-by-step explanation:

The longer than angle the longer the side tht is opposite to it... so for example, each angle and its opposite correspond to each other.. so K it is side K and so on...

first u should find the missing angles, for A, we know the angles 118 and 28 and a triangle is a total of 180 degrees, so add 118 and 28, which will give u 146, now subtract tht from 180 and u get 34, so the missing angle M is 34, now we can see which angles correspond to which side:

K = k

M = m

L = l

so the shortest will be l, then it will be m, and then it will be k

Solve for x. *<br><br> Also, Are the angles complementary or supplementary?
Anton [14]
Supplementary: straight line is 180 degree
x + (x-6) = 180
2x = 186
X = 93
