Item 8 Question 1
You ride your bike to school. As you approach an intersection, you decrease your speed by 0.75 mile per hour per second. Select an inequality that represents the time t (in seconds) until your speed decreases by more than 6 miles per hour. Then solve the inequality.

0.75 − t ≥ 6

t − 0.75 > 6

−0.75t ≥ 6

0.75t > 6

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

the answer is c
