Answer:
If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:
midpoint=(x1+x22,y1+y22)
Step-by-step explanation:

b.
i. N= 10n+120
= 10*14+120
= 260
ii. N = 10n+120
<=> 190=10n+120
<=> n=7
(0,-5/2,-1)
x(2x+5)(×+1)=0
x=0 2x+5=0 x+1=0
2x=-5 x=-1
x=-5/2
