4 / (1/4 - 5/2)
4 / (1/4 -10/4)
4 / (-9/4)
4 x (-4/9) = -16/9
Answer:
x ≠ 4 or -2
Step-by-step explanation:
the denominator cannot be zero, so factor the bottom equation to get the zeros and those are the domain restrictions.
3x^2 - 6x - 24 ≠ 0
3(x^2 - 2x - 8) ≠ 0 (factor out a 3)
3(x - 4)(x + 2) ≠ 0 (factor equation)
x ≠ 4, x ≠ -2 (use zero product property to find zeros)
Answer:
$19.99 for each cartridge.
Step-by-step explanation:
For this problem, we are finding the cost of the three printer cartridges. Since the problem says that the tax was 5.95, we can subtract that from 90.91.
90.91-5.95=
84.96
Next, since we know that the software package was 24.99, we can subtract that from 84.96.
84.96-24.99=
59.97
Finally, since there are three printer cartridges, we can divide 59.97 by 3, and get our answer.
59.97/3=
19.99
Each printer cartridge would cost $19.99.
Hope this helps and have a good day! :D
The first one is congruent because it is just turned 120degrees
