The expression would be > 0.
Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0. Since we know that x>-18, 0 is below anything we could get from this.
You could try using photo math
X=1.464102
Simplifies to: (1/2x)+1=1.732051
Step 1: Subtract 1 from both sides.
1/2x + 1 -1=1.732051-1
(1/2x)=0.732051
Step 2: Multiply both sides by 2
2*(1/2x) = (2) * (0.732051)
X=1.464102
Answer:
the function y=5x+5
plug in the hours 4.5 for x
y=5(4.5)+5
=27.5kilometers
