Amy can estimate with 10% instead, so she can just simply move the decimal point of $9.11 to the right, and so it will be estimated to more than 91 cents.
First of all to transfer <span>(2x - 1)(x + 6) = 0 into a form where we can plug it into the quadratic formula we need to use the FOIL method.
</span><span>(2x - 1)(x + 6) = 0
</span> becomes
2x*x+2x*6+-1*x+-1*6
which simplifies to
2x^2 + 12x - x - 6
and then we add like terms to get
2x^2 + 11x - <span>6
</span>
now that it is in the correct form we can identify "a" "b" and "c" by following this form
ax^2 + bx + c
looking back at the equation we got earlier
2x^2 + 11x - <span>6</span>
a=2,b=11,and c=-6
<span>Hello!
Economic policy used in the US during the second industrial revolution was the model of laissez-faire capitalism. Socialism and populism have not been used often in the US.

Step-by-step explanation:
<u>Step 1: Define Equation</u>
3.5(x + 12) = -2x + 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3.5: 3.5x + 42 = -2x + 18
- Add 2x on both sides: 5.5x + 42 = 18
- Isolate <em>x</em> term: 5.5x = -24
- Isolate <em>x</em>: x = -4.36364
