the point, M, that divides segment AB into a ratio of 3:1
A is at (-4, -2) and B is at (4, -10).
Apply section formula
Here m,n is the ratio
m =3, n= 1
A is (-4,-2) that is (x1,y1)
B is at (4, -10) that is (x2,y2)
plug in all the values in the formula
(2, -8)
Point M is (2,-9)
Answer:
He needs to work for a minimum of 4 weeks
Step-by-step explanation:
Amount he has saved=$375
Amount he needs to earns to buy a dirt bike=He earns $155 per week=155×Number of weeks he's worked(N)
This can be expressed as;
The total amount he earns=(Amount saved)+(Amount he earns per week)
Where;
Amount he needs to earn to buy a dirt bike=$900
Amount saved=$375
Amount he earns per week=155N
Replacing in the expression above
900=375+155N
900-375=155N
525/155=155N/155
N=3.4 weeks
Number of weeks=N=3.4 weeks
Minimum Number of weeks he needs to work=4 weeks
Imagine he second side is x so the first side is (x-3) and the third side is (x+4)
So x + (x-3) + (x+4) = 34
3x+1 = 34
3x=33
X=11
So longest side is (x+4) so 11+4=15
