Answer: 18 over x = -2x

Explanation:

Multiply all terms by the same value to eliminate fraction denominators,Cancel multiplied terms that are in the denominator and Re-order terms so constants are on the left,Combine exponents

Move terms to the left side

Rearrange terms

Common factor

Divide both sides of the equation by the same term

Use the quadratic formula

Simplify

Hope this helps (all the Steps to solve)

yuradex [85]

Answer: The approximate value of x is -3.396

Step-by-step explanation:

Given:

Now,to find the value of x.

Use logarithm rule:

We have,

Now,

Using value of: and we get,

on simplify:

Adding 1 both the sides, we get

Which system of linear inequalities is graphed?

ANEK [815]

To determine the system of inequality that has been graphed, we need to be very smart.

Observe that all the equations are the same.

Also note that all the lines are solid. This should tell you that the inequities should involve.

$\ge \:or\: \le$

Therefore the answer is between option A and B.

So we choose a point in the solution region to discriminate between A and B.

Let us choose the origin since that is easy to evaluate.

We substitute into option A to get.

$y\le 3x-1\:and\: x+ 3y \ge 6$

$0\le 3(0)-1\:and\: 0+ 3(0) \ge 6$

$0\le -1\:and\: 0\ge 6$

The above statements are false

We now substitute into option B

$y\ge 3x-1\:and\: x+ 3y \le 6$

$0\ge 3(0)-1\:and\: 0+ 3(0) \le 6$

$0\ge-1\:and\: 0 \le 6$

Both statements are true, therefore the correct answer is option B.

Write an appropriate direct variation equation if y = 18 when x = 2

Sergeu [11.5K]

Answer:

$y=9x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In this problem we have

y=18 when x=2

Find the value of the constant of proportionality k

$k=\frac{y}{x}$ ----> $k=\frac{18}{2}=9$

therefore

The equation is equal to

$y=9x$

A bird (b) is spotted flying 900 feet from an observer. the observer (o) also spots the top of a tower (t) at a height of 200 fe

Svetach [21]

Angle of depression = 12.52°

The right angle triangle formed has a height of 200 ft and a base of 900 ft.

The opposite side of the triangle is 200 ft while the adjacent side of the triangle is 900 ft.

Using tangential ratio we can find the angle of depression. Therefore,

Let

x = angle of depression

tan x = opposite/adjacent

opposite = 200 ft

adjacent = 900 ft

tan x = 200/900

tan x = 2/9

x = tan⁻¹ 2/9

x = tan⁻¹ 0.222

x = 12.5166739144

x = 12.52°
