Answer 10

for a) you are correct, 2 parallel lines has no solution

Answer 11

for b) the equation is 25+5x= 16+8x . solve for x to get the answer

Answer 12

for c) isolate y from the first one , it is y = 2x+1, hence it is exactly the same with the second one. So, the answer is infinitely many solution.

Answer 13

for b) 3 weeks
for c)y=0.5x+1=2x+1
1.5x=0 so x=0 put in either equation and y=1
answer(0,1) intersection
