Answer:

x = 0

Step-by-step explanation:

Step 1: Write equation

-19 = x - 19

Step 2: Solve for <em>x</em>

  1. Add 19 to both sides: 0 = x
  2. Rewrite: x = 0

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-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.<br> 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.
