Solve the second equation for x to get x=-9-y, the plug it in into the first equation, so you get 2(-9-y) -3y = 12, distribute the 2, so you get -18-2y-3y=12, add like terms so you get -18-5y = 12, then move the constants to the right so you get -5y = 30 and solve to get y=-6, and then plug it into x=-9-y to get x=-3 <span />
Answer:
you can only find an <em><u>Infinite</u></em> amount of solutions.
Step-by-step explanation:
Answer:
QR(3), RS(3), PQ(3), ST(11), RP(6), RT(14), SP(9), QT(17)
Step-by-step explanation:
The diagram is not shown, but we assume the points are in the sequence ...
P, Q, R, S, T
Since QR = RS, R is apparently the midpoint of QS, So ...
23. QR = 6/2 = 3
24. RS = QR = 3
25. PQ = QR = 3
26. ST = PT -PQ -QS = 20 -3 -6 = 11
27. RP = PQ +QR = 3 +3 = 6
28. RT = RS +ST = 3 +11 = 14
29. SP = PQ +QS = 3 +6 = 9
30. QT = QS +ST = 6 +11 = 17
