The x-coordinate increases by .75 x 4 steps from point A: 1 + 4(.75) = 4
the y-coordinate decreases by 2.5 x 4 steps from A: 5 - 4(2.5) = -10
Answer: b (4,-5)
Answer:
||u|| = sqrt((0 + 3)^2 + (4 + 2)^2) = 6.71
||v|| = sqrt((3 + 0)^2 + (3 + 2)^2) = 5.83
slope of u = 4/2 = 2
slope of v = 5/3
=> Option D is correct
Hope this helps!

Answer:
DF = 7.5
Step-by-step explanation:
Since the 3 sides are congruent, then
EF = DE , that is
4.5m - 42 = 1.5m - 9 ( subtract 1.5m from both sides )
3m - 42 = - 9 ( add 42 to both sides )
3m = 33 ( divide both sides by 3 )
m = 11
Thus
DE = 1.5m - 9 = 1.5(11) - 9 = 16.5 - 9 = 7.5
Then
DF = 7.5
Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 24 ( take the square root of both sides )
x = ± 
= ± 
= ± 
× = ± 2
