X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324
Therefore the radius, r
r = 324^0.5
r = 18
Answer:
D
Step-by-step explanation:
Lowest possible price would be when the discount is maximum (i.e 60% and then 25%)
Discount of 60% means the cost is 40% of the original price
40% of 32 = 40/100 × 32 = 12.8
Additional 25% discount means paying 75% of 12.8
75% of 12.8 = 75/100 × 12.8 = 9.6

Answer:
Step-by-step explanation:
<u>Reading rate is y pages per x minutes and proportional relationship formula is:</u>
<u>The coefficient is:</u>
<u>Let's verify if the given numbers fit into the same relationship:</u>
- 12/18 = 2/3
- 8/12 = 2/3
- 20/30 = 2/3
We confirm all same and it means k = 2/3
<u>Required equation is:</u>
This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
