Answer:
y = +6
Step-by-step explanation:
-y + 6 = 0
Subtract 6 from both sides;
-y = -6
Divide both sides by -1
y = 6
2x because its 2 times the price of the book (x)
Either it is C or D or E.
group the 1st 2 terms and last 2 terms:
(Z63 -2z^2) + (9z-18)
factor out GCF:
z^2(z-2) + 9(z-2)
now factor the polynomial:
(z-2) (z^2+9)
Answer:
b. (x-3)(x+2)
Step-by-step explanation:
y=x^2-x-6
y=x^2-3x+2x-6
=x(x-3)+2(x-3)
=(x-3)(x+2)
