Answer:

Step-by-step explanation:
Step 1:
Calculate the circumference of both circles.
The formula of a circumference:of a circle with radius r:

The circle R:

The circle S:

The length of the intercepted arc for circle R is

Step 2:
Calculate what the part of the circumference of the circle R is the intercepted arc:

The same length of the circumference of the circle S is searched for the length of the intercepted arc for circle S.
Step 3:
Calculate the length of the intercepted arc for circle S:

Answer:
Step-by-step explanation:
Rewrite -x-2y= -10 as -2y= x - 10 and then as y = (-1/2)x + 5.
Then choose any 3 x values and find the corresponding y values using this formula. For example:
x y = (-1/2)x + 5 (x, y)
----- -------------------- ---------
0 5 (0, 5)
-4 (-1/2)(-4) + 5 = 7 (-4, 7)
6 (-1/2)(6) + 5 = 2 (6, 2)
Plot these three points and then draw a line through them.
Answer:
But u only gave 25 points silly
Step-by-step explanation:
-Distribute the number outside the parenthesis into all the numbers within.
-Move the numbers with an "x" attached to it to one side and the numbers without an "x" to the other. be sure to change signs as you do (positive to negative, negative to positive)
-subtract or add the numbers on each side together
-divide the number attached to the "x" on both sides (ex. 7x=14, you divide 7)
- you get your answer (x=......)
