Answer:

z=3

Step-by-step explanation:

-12=-8z+12

-12-12=-8z

-24=-8z

-24/-8=z

z=24/8

3=z

z=3

Answer and Step-by-step explanation:

To solve for z, we have to get everything away from z.

First, subtract 12 from both sides of the equation.

-24 = 8z

Now, divide each side by 8.

-3 = z

z is equal to -3 (negative three).

Write the equation of a line perpendicular to y=1/2x + 8 that passes through ( 4, 9 ).

iogann1982 [59]

Answer:y = - 2x + 17

Step-by-step explanation:

The equation of a line, represented in the slope-intercept form, is

y = mx + c

Where

Slope = m

c = intercept

Looking at the equation given,

y=1/2x + 8

Slope,m = 1/2

If a line is perpendicular to a another line, then the slope of one line is equal to the negative reciprocal of the other line. It means that the slope of the perpendicular line that passes through that passes through ( 4, 9 ) will be -2

To determine c,

We will substitute m = -2, y = 9 and x = 4 into the slope intercept equation,

y = mx + c. It becomes

9 = -2 × 4 + c

9 = -8 + c

c = 9 + 8 = 17

The equation becomes

y = - 2x + 17

The expression cube root of 54x^8y^12 can be written in simplest radical form as

igomit [66]

Answer:

The simplest radical form of the cubic root is $3x^2y^4\sqrt[3]{2x}$

Step-by-step explanation:

Cube root of 54x^8y^12

That is:

$\sqrt[3]{54x^8y^12}$

Can be simplified as:

$\sqrt[3]{54x^8y^12} = \sqrt[3]{54}\sqrt[3]{x^8}\sqrt[3]{y^12}$

We find each separate simplification, and multiply them:

Cubic root of 54:

$54 = 2*3^3$

$\sqrt[3]{54} = \sqrt[3]{2*3^3} = 3\sqrt[3]{2}$

Cubic root of x^8

$\sqrt[3]{x^8} = \sqrt[3]{x^6*x^2} = x^2\sqrt[3]{x^2}$

Cubic root of y^12

$\sqrt[3]{y^{12}} = y^4$

Multiplying all these terms:

$\sqrt[3]{54}\sqrt[3]{x^8}\sqrt[3]{y^12} = 3\sqrt[3]{2}(x^2\sqrt[3]{x^2})(y^4) = 3x^2y^4\sqrt[3]{2x}$

The simplest radical form of the cubic root is $3x^2y^4\sqrt[3]{2x}$
