For number 16 we need to write the data as a ratio then convert to a unit rate (amount per 1)...
308/14 = x/1
Cross multiply
14x = 308 x = 308/14 x = 22
So the fuel efficiency is 22 miles per 1 gallon or
22/1
For number 17, since the car was driven at 48 mph, we just have to divide distance driven by speed to get how long it took...
288 miles ÷ 48 mph =
6 hours
How many points are shared by two perpendicular lines? but two parallel lines?
Answers
Two perpendicular lines intersect once, to form a right angle. Therefore, on point is shared by two perpendicular lines. since parallel lines never touch, there are NO points shared between the two lines.
Please help me with this ! Write a short explanation if it can but not necessary.
Answers
Unfortunately, we can't draw it for you, as the diagram is in your book! To create the line, simply find some points on the line and connect them, extending the line past each point in the same direction (you can use a ruler to help with this). To find points on the line, plug in values for x to the equation and find the corresponding y-value.
