The grade of a road is the slope of a road. in the u. s., grade is often expressed as a percent by finding the product 100(slope). approximate the grade of a road that has a rise of 950 ft over 3 mi.
a. 3%
b. 5%
c. 6%
d. 9%

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

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
