Answer:
D. 7.5 inches
Step-by-step explanation:
So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.
So, 18/6 = 3
Big:small = 3:1
So, using this we can make an equation to find AD.
Let's say ED=x.
AD is basically ED (x) + AE (5).
Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.
So, =3.
Multiply both sides by x, getting x+5 = 3x.
Subtract the x: -x -x
And you get 5=2x, giving you 2.5 = x.
However, we're not done yet, as 2.5 is the value of ED, but we need AD.
Remember, AD is = ED + AE.
So, AD = 2.5 + 5.
Finally, AD = 7.5

Answer:
the translation is 4 units at right and 2 units up
Step-by-step explanation:
see the attached figure to better understand the problem
looking at the graph
we have
The coordinates of the pre-image ABC are
A(-1,1),B(2,2),C(1,-1)
The coordinates of the image A'B'C' are
A'(3,3),B'(6,4),C'(5,1)
so
A(-1,1) ----> A'(3,3)
A(-1,1) ----> A'(-1+a,1+b)
-1+a=3 ---> a=3+1=4
1+b=3 ---> b=3-1=2
The rule of the translation is
(x,y) ----> (x+4,y+2)
That means ----> the translation is 4 units at right and 2 units up
