What is the distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3?
malfutka [58]

Answer:

The distance is \sqrt{20} or 2\sqrt{5}.

Step-by-step explanation:

Slope of parallel: 2

Slope of perpendicular: -1/2

Pick a point for y =2x + 7. For example (0,7)

Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).

Distance formula \sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2   }

Insert (0,7) and (4,5)

\sqrt{(0-4)^{2}+(7-5)^2   } = \sqrt{(-4)^{2}+(2)^2   } = \sqrt{(16)+(4)}  } = \sqrt{20}  = 2\sqrt{5}

A baker baked some loaves of bread. 240 loaves were sold by the end of the day. The baker was then left with 9/25 of the number
OLga [1]
In this case, 16/25=240 loaves that he sold
25/25 is how many loaves he started with, and 9/25 is what he now has
16/25 =240
divide bothe sides by the numerator(16) to get what 1/25 of his loaves equal
1/25=15
multiply both sides by 25 
the baker started with 375
