2. ignacio is going on vacation. he needs to drive 479 miles in 7 hours. what is his average speed in miles per
hour?
a. 71 miles per hour
c. 66 miles per hour
b. 64 miles per hour
d. 60 miles per hour

Step-by-step explanation:

Remember that

The speed is equal to divide the distance by the time

To find out the average speed or unit rate, divide the total distance by the total time

Let

x -----> the distance in miles

y ----> the time in hours

so

The average speed is x/y

substitute the values

what does muffins have to do with anything?

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
