Answer:

x and y = (2,-1)

Step-by-step explanation:

3x + 5y = -11

3x = -1 - 7y

-(-1 - 7y) + 5y = -11

y = -1

3x=-1-7x(-1)

x = 2

(x,y) = (2,-1)

-3x2+5x(-1) = -11

3x2+7x (-1) = -1

-11 = -11

-1 = -1

solution

x and y = (2,-1)

Answer:

7+3n=28 and the answer would be n=7

Step-by-step explanation:

7+3n=28 subtract 7 on both sides, that would leave 3n=21, divide 3 on both sides, the answer would be n=7 if I'm correct. I hope I helped.

Helpppp meeee fassttt pleaseeee
Yuki888 [10]

Answer:

 y = -1/3x + 3 2/3

Step-by-step explanation:

step 1. find the slope of the given line

y2-y1/x2-x1          2 - 4/ 3 + 3 = - 1 / 3

take the opposite of that and there is your slope

step 2. plug in the values to the following equation using the given point:

y - y1 = m ( x - x1 )          y - 4 = - 1/3 ( x + 1 )

step 3. solve for y

y-4 = -1/3(x+1)

-1/3(x) and -1/3(1)  ----> y-4 = -1/3x-1/3

y-4+4 = -1/3x-1/3+4  ---->  y = -1/3x + 3 2/3

P - 4 = -9 + p. Please help.
OverLord2011 [107]
Easy, take:

p-4=-9+p

Isolate the variable, this is what you are trying to find (p)

p-4=-9+p
-p        -p

-4=-9.

There is no variable, which means, there is NO SOLUTION!

You can put no solution, or ∅, as an answer.
