This is the concept of geometry, to get the expression for horizontal distance h as a function of d, we shall use the Pythagorean theorem;
c^2=a^2+b^2
thus;
hypotenuse=d
horizontal=h
slanting=8600
thus;
d^2=h^2+(8600)^2
This implies that:
d=sqrt(h^2+(8600)^2)
thus;
d(h)=sqrt(h^2+(8600)^2)
Answer: x = -9
Step-by-step explanation:
18/x = -2
18x = -2x
x = -18/2 = -9
1 3/7 because 7+3 is equal to 10. also 20/14 is an improper fraction yet still acceptable
