Answer:
Step-by-step explanation:
Given that vector a has starting point (2,3) and end point (5,7)
Direction ratios of AB = (5-2, 7-3) = (3,4)
Magnitude =
a) Starting point (0,2)
Distance= 5 units from (0,2) and direction ratios (3,4)
So the point will be of them (0+3t, 2+4t)
Distance = 5t units. So t =1
So point is (3,6)
b) When starting point =(0,5)
End point with same direction would be
(0+3, 5+4) = (3,9)
So you would substitute 3 in for A
2(a)=2(3)=6
x=6

I dont see the graph?
Step-by-step explanation:
Answer:
x ∈ R
Step-by-step explanation:
4x+x+4=8x−3x+4
Combine 4x and x to get 5x.
5x+4=8x−3x+4
Combine 8x and −3x to get 5x.
5x+4=5x+4
Subtract 5x from both sides.
5x+4−5x=4
Combine 5x and −5x to get 0.
4=4
Compare 4 and 4.
True
This is true for any x.
x ∈ R
