68 miles to 42.5 miles
Thepotemich [5.8K]
1) subtract 42.5 miles from 68 miles to find the gross change in distance:  It is 25.5.  Since this is a decrease, write -25.5 miles.
2) divide -25.5 miles by the original distance, 68 miles:
     -0.375
3) multiply this by 100% to find the percentage decrease:
     -37.5% (answer)

Find the distance between the pair of parallel lines, y = -2x+1 &amp; y = -2x+16.
balu736 [363]
Given \ the \ equations \ of \ two \ non-vertical \ parallel \ lines:\\\\y = mx+b_1\\y = mx+b_2\\\\the \ distance \ between \ them \ can \ be \ expressed \ as : \\\\d= \frac{|b_{1}-b_{2}|}{ \sqrt{ m^2+1} }

y = -2x+1\\y = -2x+16 \\\\\\d= \frac{|b_{1}-b_{2}|}{ \sqrt{ m^2+1} } =\frac{| 1-16|}{ \sqrt{ (-2)^2+1} } =\frac{| -15|}{ \sqrt{ 4+1} } =\frac{15}{\sqrt{5}}\cdot \frac{\sqrt{5}}{\sqrt{5}}=\\ \\\\=\frac{15\sqrt{5}}{5}=3\sqrt{5}\approx 3\cdot 2.24 \approx 6.72
