Solve systems by substitution (1/6)x - (1/12)y = -(1/2) and -2x + y = 6

1 answer:

5 0

This is a trick question, because the two equations are linearly dependent. If you multiply the top one by -12, you get the bottom one. This means that essentially, the same equation is written twice, so you don't have enough information to solve for x and y.

So at most you can drop one of the equations, and you are stuck with the other one.

PLEASE HELP GONNA FAIL WILL GIVE BRAINLESS

Answer: P = 166 units

Step-by-step explanation: Each point on the triangle has lines that are tangent to the circle in the triangle, meaning that those lines form a 90° angle to the middle point in the circle. There is also a rule that states if there are tangent lines coming from the points and if the points have at least one given side length, the other side will have the same side length. So if one side on point D is 41, then the other side connected to the point is 41. I added up all of the side lengths; 41 + 41 + 30 + 30 + 12 +12 = 166 units.

I hope this helps!
