#1 4/8 + 5/8 + 6/8 = 15/8 = 1 7/8
The correct answer is 1 7/8.
#2 The correct answer is YES.
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the line y = - x
a point (x, y ) → (- y, - x )
Thus
F(- 4, - 1 ) → F'(1, 4 )
G(- 10, 4 ) → G'(- 4, 10 )
2-(-4)
--------= 6
-1-7 ---= 3/4
8
y=3/4x
-4=3/4 (7)+b
-4=21/4+b
-4-21/4= -37/4
21/4-21/4=0
y=3/4x-37/4
Answer:
f(3)=3³+2×2²-2-1=27+8-3=32
