Answer:

Step-by-step explanation:
Given equation :

Standard equation of circle :

We will consider the x terms in the equation first to find a.

-2ax = 20x
a = -20x/2x = -10
a = -10
Next consider the y terms to find b.

-2by = 12y
b = -12y /2y = -6
b = -6


But the given equation constant is 15. So find the difference between 136 and 15 to find the radius : 136 - 15 = 121
Therefore, radius = √121 = 11

Stan worked 2h days this week
Step-by-step explanation:
The given is:
- Stan drives 30 minutes a day commuting to and from work
- He drove h hours this week
We need to find how many days he worked
∵ Stan drives 30 minutes a day
∵ 1 hour = 60 minute
∴ 30 minutes =
hour
∴ Stan drives
hour a day
∵ He drove h hours this week
- To find the number of days that he worked divide the total
hours he drove in this week by the hour he drives in a day
∴ The number of days = h ÷ 
- Change the division sign to multiplication sign and reciprocal the
fraction after the division sign
∵ The reciprocal of
=
= 2
∴ The number of days = h × 2
∴ The number of days = 2h
Stan worked 2h days this week

Answer:
1 2/15 loaves
Step-by-step explanation:
In a restaurant:
Total Loaf of wheat bread = 5/6
Total Loaf is white bread = 3/10
The total number of loaves that were served in all =
Loaf of wheat bread + Loaf of white bread
= 5/6 + 3/10
Lowest Common Denominator = 30.
Hence:
= 25 + 9/30
= 34/30
= 1 4/30
= 1 2/15 loaves
The total number of loaves served in all = 1 2/15 loaves
Answer:
y= 7
Step-by-step explanation:
Plug in values into y=mx+b
m= slope
b= y intercept
Since slope is 0, y will always be at 7.
y= 0(x) +7
y= 7
