Factorise x^2-y^2-2x+6y-8

Talja [164]

X^2 - y^2 - 2x + 6y - 8
= (x^2 - 2x + 1) - (y^2 - 6y + 9) - 8 - 1 + 9 
= (x - 1)^2 - (y - 3)^2 
= [(x - 1) - (y - 3) ] [(x - 1) + (y - 3)] 
= (x - 1 - y + 3) ( x - 1 + y - 3) 
= (x - y + 2) (x + y - 4)

Emma is training for a 10-kilometer race. She wants to beat her last 10-kilometer time, which was 1 hour 10 minutes. Emma has al

Mandarinka [93]

Answer:

$70 > 55 + t$

Step-by-step explanation:

Given

$Previous\ Time = 1\ hr\ 10\ mins$

$Current\ Time = 55\ mins$

Required

Represent the additional time needed as an inequality

Convert the previous time to minutes

$Previous\ Time = 1\ hr\ 10\ mins$

$Previous\ Time = 1 * 60\ mins + 10\ mins$

$Previous\ Time = 60\ mins + 10\ mins$

$Previous\ Time = 70\ mins$

Let the additional time be t

This means that she needs to run at least t minutes to beat her previous record

To beat her previous record, the sum of current time and x must be less than her previous time. i.e.

$55 + t < 70$

This can be rewritten as:

$70 > 55 + t$
