Method1:parabola
y = x^2 - 2x + 8
y-7 = (x-1)^2 ; parabola
turning point is (1,7)
method2:diff
y = x^2 - 2x + 8
y' = 2x -2 = 0 ==> x = 1,
y=7
Answer:
7x - 8
Step-by-step explanation:
5x + 2 + 2x - 10
Rearrange terms:
5x + 2x - 10 + 2
Combine like terms (add 2x and 5x):
= 7x - 10 + 2
Combine like terms (add -10 and 2):
= 7x - 8 (This is the simplified form).
Answer:
choice C is correct
Step-by-step explanation:
The clockwise sequence of vertices MNO is the opposite of the counterclockwise sequence of vertices M'N'O', so it seems some sort of reflection is involved.
Length NO is 3 times length N'O', but length NM is only 7/3 times length N'M', so the figures are <em>not similar</em>. (The ratios of side lengths must be the same for the figures to be similar.)
___
Choice D includes only rigid transformations that would ensure congruence. Similar figures may also differ by a dilation factor, so C is the better choice.
It should we around 37
