2. W<5
4. D<6 (or equal to)
Answer:
i think the answer is -18x^(2)+9x+5
-18x^(2)+9x+5
Subtract 4x^2 from −14x^2
6^3 = 216. When using chance, take the number of outcomes(six for a die) and raise it to the power of the number of repetitions
Answer:
Cody made a mistake when calculating the slope of the line and this affected every other steps after than.
She divided -3 by 6 instead of -3 by 1/6
Step-by-step explanation:
Given

1) it must be fulfilled that the denominator is different from zero, then for this expression
x^2 -9 ⇒ x^2-3^2 = (x-3)(x+3)⇒ (x-3)(x+3) = 0 ⇒ x = 3 o x = -3 , the dominium is all numbers reals except 3 and -3
