Can your provide a picture ??
Answer:
AGAIN DONT FORGET THE X
it would be "y=-4/5x+3"
Step-by-step explanation:
2+11x+121=x+96 is rearranged as: x^2+11x+121-x-96. => x^2 +10x +25, which is like ax^2+bx+c. So D = b^2-4ac = (10^2-4*1*25) = 0. So the discriminant of the given equation is 0.
Answer:
(7, -3)
Step-by-step explanation:
9x - 3y = 54
9x +1 ly = 12
Subtract both expresion
-3y - 11y = 54 - 12
-14y = 42
y = 42/-14
y = -3
Substitute y = -3 into 1;
From 1, 9x - 3y = 54
9x - 3(-3) = 54
9x - 9 = 54
9x = 54 + 9
9x = 63
x = 63/9
x = 7
Hence the solution to the system of equation is (7, -3)
