Answer: -7
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
x - c = (r + d)/y for x
x = (r +d)/y + c common denominator : (c/1) (y/1) = yc
x = (r + d)/y + yc
x = (yc + r + d)/ y
To find the rule of translation, find the change of corresponding coordinates. In this graph, for example see how A is moved to A': three units to the right, then two units down. A(-4,3)+(3,-2)=A'(-1,1). This applies to the whole shape, and is the rule of translation.
So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add that distance to 3 and 4.
By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...
d^2=3^2+4^2
d^2=9+16
d^2=25
d=√25
d=5
So the total distance of her run is 5+4+3=12 km
