Answer:
x² = 8 - (y - 8)² - 2x
x² = 16y - y² - 2x - 56
Step-by-step explanation:
∵ (x + 1)² + (y - 8)² = 9
∵ x² + 2x + 1 = 9 - (y - 8)²
∴ x² = 9 - (y - 8)² - 2x - 1
∴ x² = 8 - (y - 8)² - 2x
OR:
∵ x² = 8 - (y² -16y + 64) - 2x
∴ x² = 8 - y² + 16y - 64 - 2x
∴ x² = 16y - y² - 2x - 56
4 , divide the x by the y to find a constant
Answer:
6x(x+3)(x-2)=6x^3+6x^2-36x
3(x-2)(x +9)=3x^2+21x-54

Answer:
140
Step-by-step explanation:
Let total money spent by Eliza's be represented as x
Five times amount Eliza spent = 5x and total amount spent by Jade is $150
So it will be $10+ 5x =$150
5x= 150- 10
5x= 140
x = 140÷5
x= 28
........................
So therefore Eliza's amount spent = $28 and
5x$28 = $140
Jade spent $10 more equals $10+$140= $150(Total money spent by Jade).
K-mart is open from 8am to midnight on Monday to Saturday- there 16hrs from 8am to 12midnight
And on sunday it’s open from 10am to 8pm - so there is 10hrs from 10am till 8pm ....
So this is how you find your answer ...........✌️
*8am to 12midnight - 16hrs (Monday to Saturday)
*10am to 8pm - 10 hrs (Sunday)
*16hrs+10hrs=26
*26x7(days in a week )
*26x7=182
*therefore it’s opened for 182 hrs a week
....hrs means hours
