7. Practice: Summarizing (1 point) Classify each of your graphs as increasing, decreasing, or constant.

First bulb:

Second bulb:

8. Practice: Summarizing (2 points)

Fill in the blanks.

First bulb: When 3 is the input, the output is . When 10 is the input, the output is .

Second bulb: When 3 is the input the output is . When 10 is the input, the output is .

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
