7 x 500,000 = 3,500,000.
The towns are 3,500,000 units apart (I don't know what the cm were scale too, sorry.)
C because if you plug one into the other the answer comes out as x and that is how you know it is an inverse
The formula for the area of a triangle is 1/2*b*h=a.
1/2*b*14=56
b*14=112
b=8
Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
