Answer:

YES

Step-by-step explanation:

Any straight line can be represented by an equation of the form

Y = mX + b

where m is the slope and b is the Y intercept, so these two equations are lines. The only solution is where the two lines cross, so must satisfy both equations. Plugging in 3 for X and -2 for Y we get

Y = -3X + 7

-2 = -3(3) + 7

-2 = -9 + 7

-2 = -2 True

AND,

Y = 2X - 8

-2 = 2(3) - 8

-2 = 6 - 8

-2 = -2 True

So since both are true, yes (3, -2)  is the solution.

pantera1 [17]
Let width = w  then we have the equation:-

w(w + 12) = 448

w^2 + 12w - 448 = 0

(w - 16)(w + 28) = 0

w = 16  

Answer: the dimensions of the window are width 16 by height 28 inches

2n+7+7n=13+3n+8n <br><br><br>please help
Rasek [7]

first combine like terms so 2n + 7n which is 9n


so 9n + 7 = 13 + 3n + 8n


then combine on other side so 9n + 7 = 13 + 11n

then subtract 7 to 13 so 6

sp 9n + 6 = 11n

then subtract 9 to the other side so 2n


6 = 2n then divide all by 2

n= 3
