Answer:

First evening, 21 calls. Second evening, 26 calls. Third evening, 84 calls.

Steps:

T = 4F

S = F + 5

131 = F + S + T

Substitute in the S and T equations;

131 = F + F + 5 + 4F

126 = 6F

F = 21

Then substitute F into both T and S equations;

T = 4 * 21

T = 84

S = 21 + 5

S = 26

Answer:

The no.of call received on the first evening  = 21

The no.of call received on the second evening  = 26

The no.of call received on the third evening = 84

Step-by-step explanation:

Let the no.of call received on the first evening be x.

The no.of call received on the second evening  = x + 5

The no.of call received on the third evening = 4x

x +   x+5   +  4x   = 131

6x + 5 = 131

     6x = 131 - 5

     6x = 126

        x = 126/6

       x = 21

The no.of call received on the first evening  = 21

The no.of call received on the second evening  = 21 + 5 = 26

The no.of call received on the third evening = 4*21 = 84

Which of these describes the equation –18x + 9y = –416?
Minchanka [31]

Answer:

We conclude the equation is linear because it can be rewritten in the form y = mx + b.

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the line or linear equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

<u>Important Tip:</u>

The graph of a linear equation is always a straight line.

Convert the given equation in the slope-intercept form

18x + 9y = -416

subtract 18x from both sides

18x+9y-18x = - 18x-416

simplify

9y = -18x - 416

divide both sides by 9

y=-2x-\frac{416}{9}

Now, comparing the equation y=-2x-\frac{416}{9} with a slop-intercept form of linear equation

  • The slope m = -2
  • The y-intercept b = -416/9

Therefore, we conclude the equation is linear because it can be rewritten in the form y = mx + b.

From the attached graph, is also clear that the graph of the equation y=-2x-\frac{416}{9} is a straight line.

Hence, option D is correct.
