Answer:
first and third
Step-by-step explanation:
Consider
y =
x + 3 ( multiply through by 2 )
2y = x + 6 ← third equation
Answer:
The x-coordinate of point P is 6
Step-by-step explanation:
we have
A (2,3) and B (8,0)
we know that
Point P portions the segment AB in the ratio 2 to 1
so

and

where
AP_x represent the distance between the points A and P in the x-coordinates
AB_x represent the distance between the points A and B in the x-coordinates


The x-coordinate of P is equal to

where
A_x represent the x-coordinate of A
substitute the values

therefore
The x-coordinate of point P is 6
111km
the ratio is 1:15 so you do 7.4×15
Answer:
