Answer:
-1
Step-by-step explanation:
The attached result from a graphing calculator shows the other root to be ...
x = -1
__
The "system of equations" consists of one equation for the left side function, and one equation for the right side function. The graphs of the two equations intersect at the point where the left and right parts of the given equation are equal to each other. The graphs intersect at x=-1.
__
<em>Additional comment</em>
We prefer to subtract one side of the equation from the other, so we have a single function whose value is 0 at the root of interest. Here, that would be ...
(x^3 +x^2) -(-9x -9) = 0
x^2 +x^2 +9x +9 = 0
We would graph y = x^3 +x^2 +9x +9 and have the graphing calculator identify the x-intercept. This is shown in the second attachment. No "system of equations" is required for this.
B. is the answer because he can just refill the 1 gallon jug to eventually measure out 3 gallons!
The length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.
<h3>What is an ampere circuit?</h3>
Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”
Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.
A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.
Hence the length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.
