The two digit number can be:

21, 42, 63, 84

Now reverse those numbers and subtract to find one with a difference of 18:

21 - 12 = 9

42 - 24 = 18

The number would be 42.

Eliminate the parameter

<u> </u> $y = x -2, x\geq 1$

<u>Step-by-step explanation:</u>

In the question given correct parameter is - 2) $y = x -2, x\geq 1$

Method -

$x= t^2 + 1$ ........................(1)

$y = t^2 - 1$ ..........................(2)

Let's solve the equation 1,

⇒ $x = t^2 +1$

⇒ $t^2 = x - 1$

Put the value of t² in equation 2

$y =t^2 - 1 \\y = x -1 -1\\y = x - 2$

<u>Here we got the y parameter as </u> $y = x -2$

<u>So the option no .2 is the correct option</u> 2) <u> </u> $y = x -2, x\geq 1$

Decrease £120 by 15%

Irina-Kira [14]

To decrease this amount by 15% we must first find out what is 15% percent.

We can do that by multiplying the decimal of 15% by 120

15% = 0.15

0.15 x 120 = 18

So 18 is 15% of 120.

Wait! that's not the answer. We are asked to decrease by 15%

So 120 - 18 = 102

Your answer is £102
