A dealer receives a shipment of x vehicles. In each shipment, 30 of the vehicles are trucks and one-fourth of the remaining vehicles are cars. Which function can be used
to find the number of cars in the shipment of vehicles?

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
