<span>7x-6y=14
6x-y=-17
x = -4 y = -7 (SOLUTION) ; in ordered pair form (x,y) = (-4,-7)

-9x-24y=-48
INFINITE SOLUTIONS: general form = (x,y) = ( x, -(3x/8)+2 )

6x-y=-17
From second equation 6x - y = -17, we have y = 6x +17. Substitute this in the first equation to get
7x-6y=14
>> 7x-6(6x+17)=14
>> 7x-36x-102=14
>> 7x-36x=102+14
>> -29x=116
>> x=116/(-29)
>> x=-4
Now plug this value in y = 6x +17, to get
y = 6(-4) + 17 = -24 +17 = -7
So x = -4, y = -7 is the solution.
The answer would be 30.51
Your answer is A. x/2+1000
the mother recieved $4000 and the son recieved $3000, $4000/2 equals $2000, $2000 plus $1000 equals $3000
hope I helped please thank, rate, and award me best answer if you're on desktop :)
There are two congruent triangles that are being formed from the lamppost, the light, the ground and the man. Always try to draw a picture for these types of problems. It helps a lot when solving. Your answer should be about 4.3ft
