By using the general equation for a circle, we will see that the correct options are:
1) This is a circle centered at (-3, - 5) with a radius of 4 units.2) The center is (-3, 5) and the radius is 2 units.3) The center is (3, 5) and the radius is 2 units.4) This is a circle centered at (3, - 5) with a radius of 4 units.How to write a circle equation?
For a circle of radius R and center (a, b), the equation is given by:
(x - a)^2 + (y - b)^2 = R^2
With that in mind, if we look at the first equation:
(x + 3)^2 + (y + 5)^2 = 16 = 4^2
This is a circle centered at (-3, - 5) with a radius of 4 units.
For the second equation:
(x + 3)^2 + (y - 5)^2 = 4 = 2^2
The center is (-3, 5) and the radius is 2 units.
The third equation is:
(x - 3)^2 + (y - 5)^2 = 4 = 2^2
The center is (3, 5) and the radius is 2 units.
The fourth equation is:
(x - 3)^2 + (y + 5)^2 = 16 = 4^2
This is a circle centered at (3, - 5) with a radius of 4 units.

So, first we have to put in an equation

multiply 9/10 by 2
So you get 9/20+ 2 18/20
Add the fractions together and you'll get 26/20

Find the value of x.
Answers
Answer:
41
Step-by-step explanation:
76, x and 63 are linear pair angles.
Sum of linear pair angles is 180,
76 + x + 63 = 180
x + 76 + 63 = 180
x + 139 = 180
x = 180 - 139
x = 42
A straight line is 180 degrees so i do 76+63 which is 139 and 180-139 which is 41

Explanation:
Let's say Phil passes his brother at a sign post, and let's say the sign post is x miles into the 6 mile hike. This means 0 < x < 6.
Once Bill reaches the sign post, he turns around to walk back x miles. His faster brother Phil bikes the remaining 6-x miles to the trail end, before coming back to bike an additional 6 miles to get to the trailhead again. Phil arrives back at the same moment Bill does.
Overall, Phil travels 6-x+6 = 12-x miles in the same amount of time Bill walks back x miles. I recommend drawing out a number line diagram to see why this is the case.
-------------
For Bill, we have this equation
distance = rate*time
x = r*t
r = x/t
Phil has the equation
distance = rate*time
12-x = (3r)*t
Notice that Phil's rate is three times that of Bill. The t is the same for both brothers because they travel in the same timespan.
Plug in r = x/t and solve for x. The t variables divide and cancel.
12-x = 3*(r)*t
12-x = 3*(x/t)*t
12-x = 3x
12 = 3x+x
4x = 12
x = 12/4
x = 3
Phil passed Bill at the 3 mile marker.
This is why the answer is choice B.

You helped 3.6 customers per half hour yesterday so I helped how many customers in 7,.5 hours yesterday
Answers
Step-by-step explanation:
I guess, "you" and "I" are working with the same efficiency and work rate.
and with the typos in it, it is not clear, if I understood the problem and the given data properly.
but based on what I understood :
so, 3.6 customers in 0.5 hours.
7.5 hours × 2 = 15 times 0.5 hours.
15 × 3.6 = 54 customers.
so, with the same work rate as you, I helped 54 customers in 7.5 hours.
