-3x+9y =18

add 3x to each side

9y = 3x+18

divide by 9

y = 3/9 x +18/9

y = 1/3 x+2

the slope is 1/3

the y intercept is 2

-3x+9y =18

let y=0 to find the x intercept

-3x=18

divide by -3

x=-6

the x intercept is -6

NEED HELP I GOT 15MINS%$!

goldenfox [79]

Answer:

The answer is option 2.

Step-by-step explanation:

First, you have to eliminate brackets, you have to divide -1.5 to both sides :

$- 1.5(4 - r) = - 12$

$- 1.5(4 - r) \div - 1.5= - 12 \div - 1.5$

$4 - r = 8$

Next you have to solve r :

$4 - r = 8$

$- r = 8 - 4$

$- r = 4$

$r = - 4$

Prove that: (12^13–12^12+12^11)(11^9–11^8+11^7) is divisible by 3, 7, 19, and 37. The answer should be like: x^b*3*7*19*37. Also

Answer:

Step-by-step explanation:

Given (12^13–12^12+12^11)(11^9–11^8+11^7),

(12^13–12^12+12^11)(11^9–11^8+11^7) =

[(12^12)12 – 12^12 + 12^11][(11^8)11 – 11^8 + 11^7)

[(12^12)(12 – 1) + 12^11][(11^8)(11 – 1) + 11^7] =

(12^12(11) + 12^11)(11^8(10) + 11^7) =

(12^11(12x11) + 12^11)(11^7(11x10) + 11^7) =

[(12^11)(12x11 + 1)][(11^7)(11x10 + 1)] =

[(12^11)x(11^7)](12x11 + 1)(11x10 + 1) =

[(12^11)x(11^7)](133 x 111) =

[(12^11)x(11^7)](14763) =

[(12^11)x(11^7)](3x7x19x37)

From here, it is clear that the given number is divisible by 3, 7, 19 and 37.
