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)

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

What is 18 & 20 & can you show work please??

irina1246 [14]

18. Make the values have the same denominators.

4 2/3(8/8)= 112/24
5 3/8 (3/3)= 129/24

Add the values

112/24+129/24= 241/24

Simplify the answer

241/24= 10 1/24

The answer for question 10 1/24 ounces.

20. Multiply 1 1/4 by 5. (There are 5 days from Monday through Friday)

1.25(5)= 6 1/4

The answer to question 20 is 6 1/4.

Hope this helps!
