Please help i'll mark as brainliest. Even if you can only answer one its ok. 3. Without graphing how will you know if the graph is a set of parallel lines? Intersecting lines? Lines that coincide? 4. What do graphs indicate about the values of the variables in the system? 5. In what way can your understanding of graphs of systems of linear equations help you in determining the most favorable options in life?

by slope of given eq

for parallel line slope are same

for intersection line slope are different

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: no

you are only given the cost not the amount of pounds.
