Solve the system using the substitution or elimination method {2x−6y=8,−3x+9y=−12. how many solutions are there to this system? a. none b. exactly 1 c. exactly 2 d. exactly 3 e. infinitely many f. none of the above if there is one solution, give its coordinates in the answer spaces below. if there are infinitely many solutions, enter x in the answer blank for x and enter a formula for y in terms of x in the answer blank for y. if there are no solutions, leave the answer blanks for x and y empty.

ok

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
