Maksim231197 [3]

Answer:

200

Step-by-step explanation:

<u>Step 1:  Add</u>

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

1 + 2 = 3

3 + 3 = 6

6 + 4 = 10

10 + 5 = 15

15 + 6 = 21

21 + 7 = 28

28 + 8 = 36

36 + 9 = 45

45 + 1 = 46

46 + 2 = 48

48 + 3 = 51

51 + 4 = 55

55 + 5 = 60

60 + 6 = 66

66 + 7 = 73

73 + 8 = 81

81 + 9 = 90

90 + 10 = 100

<em>100</em>

<u>Step 2:  Multiply</u>

100 * 2

<em>200</em>

Answer:  200

Find the Quetion of the line that passes through the points (1,6) and (5,2)
NemiM [27]

Answer:

y=-x+7

Step-by-step explanation:

Equation of straight line is given as

y-y_1=m(x-x_1)

where slope m is calculated as

m=\frac{y_2-y_1}{x_2-x_1}

<u>Here </u>

(x_1, y_1)=(1, 6) \ \ and \ \ (x_21, y_2) = (5, 2)

m = \frac{2 - 6}{5 - 1}\\m=\frac{- 4}{4} \\m=-1

<u>Equation of line that passes through the points (1,6) and (5,2)</u>

<u />y-6=-1(x-1)\\y=-x+7<u />
