The answer would be
x² + 18x + 81 = 44 + 81
To complete the square, we look at the value of b (the coefficient of x). We take half of it, then square it; this is the number that gets added to both sides.
18/2 = 9; 9²=81
Therefore we add 81 to both sides.
Answer:
Step-by-step explanation:
Slope = (-1+11)/(-4-1) = 10/-5 = -2
Equation of a line is
y +11 = -2(x-1)
y = -2x +2 -11
y = -2x -9
Answer:
Sorry but i don’t know what a would be because I didn’t learn that yet, but I can help with b
