G=x-c/x. for x how do yoy make this an equation for x? help

zzz [600]

1.
$\displaystyle \text{if }\quad G=x- \frac{C}{x} \\\\$

$x \neq 0$

Multiply both sides by x:

$\displaystyle Gx=x\bigg(x- \frac{C}{x}\bigg )\\\\Gx=x^2-C$

Subtract from both sides Gx:
$Gx-Gx=x^2-C-Gx\\x^2-Gx-C=0$

Then solve this equation:

$\displaystyle x^2-Gx-C=0\\\\x_{1,2}= \frac{G\pm \sqrt{G^2+4C} }{2}$

2.
$\displaystyle\text{if}\quad G= \frac{x-C}{x}$

$x \neq 0$

Multiply both sides by x:

$Gx=x-C$

Subtract from both sides Gx:

$x-C-Gx=0$

Then solve this equation:

$\displaystyle x-Gx-C=0\\x(1-G)=C\\x= \frac{C}{1-G}$

Linear or nonlinear tables?

Oxana [17]

Table 1 and Table 2 are linear tables while table 3 is a non-linear table.

Step-by-step explanation:

Step 1; If y's value is dependent on the value of x, it is a linear relationship i.e. as the value of x varies, y also varies correspondingly. So x is independent while y is dependent on x i.e. the value of y depends on the value of x. We need to determine if there is a linear relationship between the values of x and y in the given tables.

Step 2; In table 1, the values of y are squares of the values of x i.e. 1² = 1, 2² = 4, 3² = 9, 4² = 16, 5² = 25. So the relationship is y = x². So table 1 is a linear table i.e. values which exist in a linear relationship.

Step 3; In table 2, the values of y are obtained by summing two times the value of x and 4.

when x = 1, y = 2(1) + 4 = 6,

when x = 2, y = 2(2) + 4 = 8,

when x = 3, y = 2(3) + 4 = 10,

when x = 4, y = 2(4) + 4 = 12,

when x = 5, y = 2(5) + 4 = 14.

So y = 2x + 4, so table 2 is also a linear table.

Step 4; There is no relationship between the values of y and x. For the negative values of x, y = -x while for positive values of x, y = x, there is no constant relationship between the values of y and x. So table 3 is a non-linear table.

Alan drew several three-dimensional figures. Which of the following figures has exactly 5 faces and 5 vertices?

Marat540 [252]

Answer:

Rectangular Pyramid

Step-by-step explanation:

we know that

A rectangular pyramid is a three-dimensional figure that has a rectangular base and four lateral triangular faces

The total number of faces is 5 (one rectangular face plus four triangular faces)

The total number of vertices is 5 (four at the base and one at the apex)
