The first step for solving this equation is to determine the defined range.
\frac{1}{4z} = - \frac{7}{8} +  \frac{1}{8z}, z ≠ 0
Move the expression\frac{1}{8z} to the left side of the equation and change its sign.
\frac{1}{4z} - \frac{1}{8z} = - \frac{7}{8}
Now we need to write all numerators above the least common denominator of 8z. This will change the equation to the following:
\frac{1}{8z} = - \frac{7}{8}
Simplify the equation using cross multiplication.
8 = -56z
Switch the sides of the equation.
-56z = 8
Divide both sides of the equation by -56.
z =  -\frac{1}{7}, z ≠ 0
Lastly,, check if the solution is in the defined range to get your final answer.
z = -\frac{1}{7}
Let me know if you have any further questions.

6(x²-4x+4-4)+1=0, 6(x-2)²-24+1=0, 6(x-2)²=23, x-2=±√(23/6), x=2±√(23/6)=2±1.95789, so x=3.95789 or 0.04211 approx. These are the zeroes.

Use the info given to find the new price: original price: $24 and discount rate: 11%. What is the new price????
ELEN [110]
So I think you have to find 11% of 24 and that is 11/100 x 24 = 2.64$. Then you reduce it to the real price 24-2.64= 21.36$ (the new prize). I might be completly wrong but I hope this helps

The perimeter of a parallelogram is 76 inches and 1 side measures 14 inches of it can be determined what are the lengths in inch
nydimaria [60]

The dimension of the parallelogram ABCD will be 14 inches, 48 inches, 14 inches and 48 inches.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

The perimeter of a parallelogram is 76 inches.0

And one side measure is 14 inches.

Then the rest of the sides will be

We know that opposite sides are prallel and equal.

Let ABCD is a parallelogram.

AB = CD = 14 inches

BC = AD = x

Then the value of x will be

We know

 P = 2(AB + BC)

76 = 2(14 + x)

 x = 48
