Answer:
1) B. similar
2) D. (4, 2)
Step-by-step explanation:
1)
When a figure is dilated, the shapes will be similar. Reflected is another transformation so that's wrong. Same size and congruent is wrong since that would have to make the dilated size equal which can't since it's contradicting.
2)
B: (4, -2)
Reflection across the x-axis:
(x, y) → (x, -y)
(4, -2) → (x, -y)
(4, 2)
y = 1/2 x
We have the slope of 1/2 and a point of (4,2)
We can use point slope form
y-y1 = m(x-x1)
y-2 = 1/2(x-4)
Distribute
y-2 = 1/2x -2
Add 2 to each side
y-2+2 = 1/2 x -2+2
This is in slope intercept form
Look below
6/10 (or 60%) of the pies are cherry
a = √10
a² + b² = c²
a² + 9² = (√91)²
a² + 81 = 91
a² = 10
hope this helps :)
