Answer:

x = 0

Step-by-step explanation:

Step 1: Write equation

-19 = x - 19

Step 2: Solve for x

Add 19 to both sides: 0 = x
Rewrite: x = 0

Step 3: Check

Plug in x to verify it's a solution.

-19 = 0 - 19

-19 = -19

Which calculation can be used to find the value of y in the equation y3 = 27

zalisa [80]

You just divide each side of the equation by three so you'll get $y = 9$

Edit: I believe you wrote the equation wrongly. If it was $y^3 = 27$ , then you cubic root both sides and get $y = 3$ .

Graphing Logarithmic Expressions In Exercise, sketch the graph of the function. y = Inx/3

Alexus [3.1K]

Answer:

The attached image shows the graph for the given function.

Step-by-step explanation:

We are given the function:

$y = \ln\big(\dfrac{x}{3}\big)$

We have to graph the given function.

Properties of given function:

The given function is a log function of the form $y = c\log_a(\frac{x}{3}) + b$
Here a = e(exponential constant), b = 0 and c = 1
There are no y intercept for the given function.
The x-intercept is $(3,0)$
The range of the given function is $(-\infty,\infty)$
The domain of the given function is $(0,\infty)$

The attached image shows the graph for the given function.

Viktor [21]

Answer:

The difference in the cost of book between Portugal and England is £2.37.

Step-by-step explanation:

Given,

Cost of book in Portugal = €34.95

Cost of book in England =£27.50

We need to find the difference in pounds (£) between for cost of the book in Portugal and England.

Solution,

Firstly we will find out the cost of book bought in Portugal in pounds.

We have also given that;

£1 = €1.17

Here we use the unitary method to find the cost in pounds.

Since €1.17 =£1

$\therefore 34.95=\frac{34.95}{1.17}=\£29.87$

also given that the cost of book in England is £27.50.

Now we will find the difference, which is equal to cost of book in England minus cost of book in Portugal.

Difference = $\£29.87-\£27.50=\£2.37$

Hence The difference in the cost of book between Portugal and England is £2.37.
