X+2(x+y)=7 3(x-y)=1-2y What is x&y???? Please answer asap!!!!

1 answer:

X= -x over 2 (negative x as a fraction and 2 is the denominator) minus y+ (seven as the numerator over 2 as the denominator).
Solve for y by simplify both sides with inverse operations, then isolate the variable and you get, y = 3x - 1.

Line AB contains points A (8, −4) and B (1, −5). The slope of line AB is....

shutvik [7]

Answer:

$The\ slope\ of\ the\ line\ AB\ is \frac{1}{7} .$

Step-by-step explanation:

Formula for slope

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

As the Line AB contains points A (8, −4) and B (1, −5).

Put points value in the above

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$m = \frac{- 5- (-4)}{1 - 8}$

$m = \frac{- 5 + 4}{1 - 8}$

$m = \frac{- 1}{-7}$

$m = \frac{1}{7}$

$Therefore\ the\ slope\ of\ the\ line\ AB\ is \frac{1}{7} .$

HURRYYYYYY !! A cube has an edge length of 9 centimeters.

CaHeK987 [17]

The perimiter is 4 times 1 side
currently, it is 9 times 4 or 36

increased by 3
I think y mean times 3
so 9*3=27
new perimiter is 27*4=108

how much larger is it?
108-36=72

it is 72cm larger

it is the first answer
(it isn't cm² because that is for area and we are calculating perimiter)
