Answer:
3x³ - 12x + 4
Step-by-step explanation:
The opposite of a polynomial P is -P.
You find the opposite of P by multiplying it by -1.
P = -3x³ + 12x - 4
-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term
= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1
= 3x³ + (-12)x - (-4)
= 3x³ - 12x + 4
Answer:
(-2, 2)
Step-by-step explanation:
x= -2 y= 2
Answer:
0.96 or .96
Step-by-step explanation:
40 divided by 100 = 0.4 to change the percent to a decimal
and multiply 2.40 to 0.4, 0.4 times 2.40 is 0.96 or .96
<span>A) 2x + 4y = 14
B) 4x + y = 20
If you multiply equation A by -2, then when the equations are added, the x will be eliminated.
The solutions are:
X = 4.714285714285714
Y = 1.1428571428571428
