The answers is:
D={2,6,7}
You know that it is the domain because it is at the beginning of the parenthesis and is always x.
(x,y) if you were looking for y you would be looking for the second number in the parenthesis and that is know as range.

ITS been increased by 39%

Alenkasestr [34]

Answer:

Step-by-step explanation:

Let 'x' be the original price.

x + 39% of x = 197.38

x + 0.39 x = 197.38

1.39x = 197.38

x = 197.38/ 1.39

x = 142

8 identical pens cost £12 work out the cost of 10 of these pens

katen-ka-za [31]

Ok. So, if 8 pens cost £12. Then we would divide £12 by 8. Each pen costs £1.5.

So now we are going to multiply £1.5 and 10. £1.5*10=15.

The total of 10 pens is £15.

I hope this helps, if you need any additional help, just ask. I am here to help you as needed.

Find the value of x.

Tatiana [17]

$\large \mathfrak{Solution : }$

The given pair of angles are vertical opposite angle pair so, they are equal. i.e

$(x + 90)\degree = 4x\degree$

$(4x - x) \degree= 90\degree$

$3x\degree = 90\degree$

$x\degree = \dfrac{90\degree}{3\degree}$

$x\degree = 30\degree$
