Answer:
(x-4)*2 + (y-2)*2 = 25
Step-by-step explanation:
(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
h = 4
k = 2
r = 5
sub in all this info:
(x-4)*2 + (y-2)*2 = 25
to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

you can use cross multiplication to solve for x:


so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
<em>The ratio of shared costs of mean=2:3.
One person paid the cost </em>£<em>52.20, so let the other person paid the cost be X.
</em><em>(2/3)=(52.20/X)
</em><em>X=(52.20</em>×3)/2
X=26.10×3
X=78.30
So the gross cost paid by both the person = £(78.30+52.20)
⇒£130.60
Answer: All points in the shaded region after 2y<-12x+4 is the solution.
Step-by-step explanation:
Since we have given that

We need to find the point of solution to the system of inequalities:
Suppose

We first check the consistency of the system of equation:

So, it is parallel system of equations, but we consider it as an inequality, so all the points in the shaded region is the solution.
Using zero test,

0<4 it is true so, shaded part is towards the center.
Similarly,

0<4 again it is true it would be shaded towards the center.
So, the common part will be after 2y<-12x+4 .
Hence, all the points in the shaded region is the solution.
Answer:
60 miles
Step-by-step explanation:
let d = distance to the lake
Using: time = distance ÷ speed
Create expressions for the time it takes for each journey:
Drive: 
Walk: 
If total time = 17 hours






Therefore she walked 60 miles
