For a ride on a rental scooter, Deon paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for
faltersainse [42]

Answer:

66 minutes

Step-by-step explanation:

11.96 - 8 =3.96

Every 10 minutes Deon pays 60 cents because 6 times 10 = 60 and every 6 minutes Deon is paying 36 cents

10 min = 60 cents

20 min = $1.20        

40 min = $2.40

50 min = $3.00

60 min = $3.60

6 min = 36 cents

Then you do 3.60 + 36 which equals $3.96

How to figure how the minutes is just 60 + 6 = 66 minutes

For what value of a are the lines of 6y=-2x+4 and 2y=ax-5 parallel? perpendicular?
masha68 [24]

Hey there!!

Parallel lines have the same slope. If they have different slope, then they are not parallel because both lines would combine at some point.

The y-intercept form:

<em>y = mx + b </em>

<u>In this equation, 'm' is considered to be the slope. </u>

The equation we have is 6y = -2x + 4

First, let's divide all the sides with 6 to isolate the value of 'y'.

... 6y = -2x + 4

... y = -1/3x + 2/3

<u><em>The slope is -1/3... </em></u>

<u><em>... hence the slope in the other equation should be -1/3. </em></u>

Equation we got...

... 2y = ax - 5

Let's divide by 2 on both sides...

... y = ax/2 - 5

The slope in this a/2

<u><em>Hence, ... </em></u>

<u><em>... a/2 = -1/3 </em></u>

<u><em>... 3a = -2 </em></u>

<u><em>... a = -2/3 </em></u>

<h2><u><em>Hence, the value of a is -2/3. </em></u></h2><h3><u><em>Hope my answer helps!</em></u></h3>
