Me with these two. i have no teacher and i do not recall trhis

It shows a contradiction because (a − 4b) / b is a rational number and √5 is an irrational number.

Step-by-step explanation:

A rational number can be written as a ratio of two integers.

An irrational number cannot.

(a − 4b) / b is a rational number.

√5 is an irrational number.

the f

last graph i believe

step-by-step explanation:

worked it out i believe

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
