-\dfrac{16}{12}=-\dfrac{16:4}{12:4}=-\dfrac{4}{3}=-1\dfrac{1}{4}\\-------------------------\\\text{Your solution of a system of equations is incorrect.}\\\\\text{Correct is}\\\\\left\{\begin{array}{ccc}6x+5y=4&\text{multiply both sides by 7}\\6x-7y=-20&\text{multiply both sides by 5}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}42x+35y=28\\30x-35y=-100\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad72x=-72\qquad\text{divide both sides by 72}\\.\qquad\boxed{x=-1}

\text{Put the value of x to the first equation:}\\\\6(-1)+5y=4\\-6+5y=4\qquad\text{add 6 to both sides}\\5y=10\qquad\text{divide both sides by 5}\\\boxed{y=2}\\\\Solution\ of\ the\ system\ of\ equations:\ \boxed{x=-1\ and\ y=2}


\text{After adding both sides of the equations in this form.}\\\text{Then you will get}\\\\12x-2y=-16\ not\ 12x=-16

Can someone illustrate 4\6 yards and 5/7 yards on an number line. I need help

4/6 =.66×36inches in a yard=24 in
5/7=.71 =25.5 inches

As you can tell 24 in comes first and less than 25.so 4/6 is smaller than 5/7

Is x + 2 a factor of x^20 - 4x^18 + 3x - 6
KiRa [710]

Answer: (x-2) is not a factor

Step-by-step explanation:

x^20 - 4x^18 +3x - 6 = 0 is a polynomial.

To test if (x + 2) is a factor, we are to use factor theorem

Make x the subject of the formula

x + 2 = 0

x = 0 - 2

x = -2

Put x = -2 into the equation. If the result on both the left hand side and right hand side is 0, then (x + 2) is a factor

(-2)^20 - 4(-2)^18 + 3(-2) - 6 = 0

1048576 - 4(262144) -6 -6 =0

1048576 - 1048576 -12 = 0

0 -12 = 0

-12 =0

Since LHS is not equal to RHS. (x+2) is not a factor of the equation
