Answer:

y = -2x + 170

Step-by-step explanation:

(30, 110)    (40, 90)                          y = mx + b

x1      y1     x2    y2                         90 = -2 (40) + b

<u>90  -  110 </u>=  <u> -20</u>   =  -2                 90 = -80 + b

40  -  30        10                           <u>+80</u>  <u> +80</u>

                                                     170 = b

really hope this helps :)

Find the set below using A=(5,6,9), and so on (Explanation is in picture)
anzhelika [568]

The result is: {5,6,9}

Step-by-step explanation:

Given

U = {0,1,2,......,10}

A = {5,6,9}

B = {0, 6, 7, 10}

We have to find

(A∩B)U(A∩B')

First of all,

<u>B':</u>

B' = U -B = {0,1,2,......,10} -  {0, 6, 7, 10}

= {1,2,3,4,5,8,9}

<u>A∩B':</u>

A∩B' = {5,6,9} ∩ {1,2,3,4,5,8,9}

= {5,9}

<u>A∩B:</u>

A∩B = {5,6,9} ∩ {0, 6, 7, 10}

={6}

At the end we have to find union

(A∩B)U(A∩B') = {6} U {5,9}

(A∩B)U(A∩B') = {5,6,9}

Hence,

The result is: {5,6,9}
