Simplify completely: the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative
True [87]
The answer is <span>a.−4x^2 − 3x + 2
</span>
the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative 2 times x is: \frac{8 x^{3}+6 x^{2} -4x }{-2x}

\frac{8 x^{3}+6 x^{2} -4x }{-2x} =  -\frac{8 x^{3}+6 x^{2} -4x }{2x}=- \frac{2x*4 x^{2} +2x*3x-2x*2}{2x} =- \frac{2x(4x^{2} +3x-2)}{2x} = \\  \\ =-(4x^{2} +3x-2)=-4x^{2} -3x+2

Samantha is going on vacation for the summer and is trying to choose between two different plans. The first plan costs $450 for
ziro4ka [17]
Pretend the cost of the hotel is called "x" and the amusement park is "y"
make the equations.
450=3x+2y  and  700=5x+3y
since you're solving for amusement park, you basically just solve for y
multiply the first equation by 5 and the second equation by 3.
2250=15x+10y  and  2100=15x+9y
these are a system of equations so subtract one from the other to cancel the x values away.
150=y   so the answer is that a day trip to the amusement park costs $150
