Answer:
a) 3/2 or 1.5
b) 2/3 or ≈.66
Step-by-step explanation:
AB corresponds to DE because they are both the longest sides of their respective triangles.
a) The scale factor would be what you would multiply 8 by to get 12. 12/8 is 3/2 or 1.5
b) The scale factor would be what you multiply 12 by to get 8. 8/12 is 2/3 or ≈.66
The answer is 5/2
y2-y1/x2-x1
9-4/7-5 = 5/2
3x -3y = 6
or, 3(x -y)= 6
or, x-y =6/3
or, x-y = 2
or, x=2+y........eqn(i)
4x - 7y = 2
substituting the value of x from eqn(i)
or, 4(2+y) -7y = 2
or, 8 + 4y -7y = 2
or, -3y = 2-8
or, y = -6/-3
■ y=2
so in eqn(i)
x= 2+y
x= 2+2
■x = 4
