Answer:

 y = -1/2x + 4

Step-by-step explanation:

We have two points ( 8,0) and ( 0,4)

We can find the slope

m =(y2-y1)/(x2-x1)

    = (4-0)/(0-8)

    4/-8

   -1/2

We can use the slope intercept form

 y = mx+b where m is the slope and b is the y intercept

 y = -1/2x + 4

Step-by-step explanation:

<u>Blank</u><u> </u><u>C</u> :

Given total = 68

No. of TV news = 13

Therefore, in Internet it would be = Total - TV news

= 68 - 13 = <u>55 (ans)</u>

<u>Blank</u><u> </u><u>D</u> :

No. of Internet news in 7th grade = 55

No. of Internet news in 8th grade = 64

Hence, total Internet base news = 64 + 55 = <u>119 (ans)</u>

<u>Blank</u><u> </u><u>B</u> :

All total = 138

Internet news total = 119

Hence, TV news total = All total - Internet news

= 138 - 119 = <u>19 (ans)</u>

<u>Blank</u><u> </u><u>A</u> :

No. of TV news in 7th grade = 13

Total news in TV = 19

Therefore, no. of TV news in 8th grade = 19 - 13 = <u>6(ans)</u>

<u>Blank</u><u> </u><u>E</u> :

All total = 138

Total of 7th grade news = 68

Hence, total of 8th grade news = 138 - 68

= <u>70 (ans)</u>

Answer:

21 1/3 inches

Step-by-step explanation:

Inverse variation means that when the frequency goes up by a factor of 576/256 = 9/4, the length of the string goes down by a factor that is the inverse of that, 4/9.

4/9·48 inches = 21 1/3 inches
