To graph the line we need two points; we already have one the point (4,2) now we need to find another one; to do this we get the equation of the line given by:

y-y_1=m(x-x_1)

where m is the slope and (x1,y1) are a point throught the line. Plugging the values given we have:

\begin{gathered} y-2=1(x-4) \\ y-2=x-4 \\ y=x-4+2 \\ y=x-2 \end{gathered}

Now we give a value to x and find the corresponding y. If x=0, then:

y=-2

hence we have the point (0,-2).

Now that we have two points (0,-2) and (4,2) we graph them on the plane and join them with a straight line, hence the graph is:

of all the songs on a playlist, 1/3 are rock, 1/8 are dance, and the rest are country. what fraction of all the songs on the pla
igomit [66]

Answer:

13/24

Step-by-step explanation:

First, it would be easier to find the common denominator of 1/3 and 1/8. The easiest way to do that is to do 3x8=24. This means the common denominator is 24 and so we must convert the fractions so they have this denominator.

1/3 --> 8/24

1/8 --> 3/24

Now, we can simply add these fractions together to find out the fraction of songs that are NOT country songs.

8/24 + 3/24 = 11/24 songs are not country songs.

To find out the fraction of songs that are country, simply do 1 (or 24/24) take away 11/24.

24/24 - 11/24 = 13/24 songs are country songs.

1. a type of bamboo holds a Guinness world record for the fastest growing plant.is can grow 91cm a day. how fast in inches per h
nikdorinn [45]

1-

Given length is 91 cm

1 cm = 0.3937 inch

so, 91 cm = 91* 0.3937 = 35.826 inches

1 day = 24 hours

In 24 hours the bamboo grows = 35.826 inches

In one hour it will grow = \frac{35.826}{24}

= 1.492 inches per hour. Hence the bamboo grows 1.492 inches per hour.


2-

We have to convert hours and seconds in minutes.

1 hour = 60 minutes

so 10 hours = 60 * 10 = 600 minutes.

60 seconds = 1 minute

so 24 seconds = \frac{24}{60} = 0.4 minutes.

Now we have been given the total time as 10 hours, 39 minutes and 24 seconds

So adding all values in minutes, we get

600 + 39 + 0.4 = 639.4 minutes

So Saturn takes 639.4 minutes to complete one rotation

Mila [183]

The equation for this is quite simple. Take note x is the amount of shirts sold and 5.25 is the cost for each one to which they add a 75 setup fee.

So the equation will be

75+(5.25x)=
