Consider the system of linear equations  -4x+2y=4   and  4x-y=-6 which is different

x= -2, y = -2

Step-by-step explanation:

Solve the following system:

{2 y - 4 x = 4 | (equation 1)

{4 x - y = -6 | (equation 2)

Add equation 1 to equation 2:

{-(4 x) + 2 y = 4 | (equation 1)

{0 x+y = -2 | (equation 2)

Divide equation 1 by 2:

{-(2 x) + y = 2 | (equation 1)

{0 x+y = -2 | (equation 2)

Subtract equation 2 from equation 1:

{-(2 x)+0 y = 4 | (equation 1)

{0 x+y = -2 | (equation 2)

Divide equation 1 by -2:

{x+0 y = -2 | (equation 1)

{0 x+y = -2 | (equation 2)

Collect results:

 {x = -2 , y = -2

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
