Equations, Their Slopes And Y-intercepts. Please 9,11 and 12 question! Thank you!)
MakcuM [25]

Hey there!

(9) 2x-9y=45

... -9y=-2x+45

... y = (2/9)x - 5

Slope = 2/9

y-intercept = (0,-5)

(11) 3y+2x=-15

... 3y=-2x-15

... y = (-2/3)x - 5

Slope = -2/3

y-intercept = (0,-5)

(12) 10x+8y=40

... 8y=-10x+40

... y=(-10/8)x+5

Slope = -5/4 (after simplifying )

y-intercept = (0,5)

Hope my answer helps!

Help me decrease 25 by 30%
Marysya12 [62]

Step-by-step explanation:

Percentage decrease = 30% × 25

New value = 25 - Percentage decreaseNew value =

25 - Percentage decrease =

25 - (30% × 25) =

25 - 30% × 25 =

(1 - 30%) × 25 =

(100% - 30%) × 25 =

70% × 25 =

70 ÷ 100 × 25 =

70 × 25 ÷ 100 =

1,750 ÷ 100 =

17.5

Absolute change (actual difference) =

New value - 25 =

17.5 - 25 =

- 7.5
