Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
Step-by-step explanation: If you take a look at the right side of the equation, a 3 is being added to our variable <em>x</em>.
If you were going to solve this equation, you must subtract 3 from the right side and the left side to isolate our variable.
You would end up with 4 = x.
Alright lets interpret this first.
x - 4 = 4( x + 2 )
This question is basically asking you if it has infinite, none or only one solution.
To figure out no solutions you would need to find out if x = anything.
let's simplify first!
x - 4 = 4x + 8
Now once you remove all the parenthesis you can actually take out two options.
Infinite and No Solutions.
It is not infinite because in its simplest form they are still different.
It is not no solutions because it can still be done (they aren't impossible)
Example:
No solution -> (x+2)=(x+3)
Infinite -> (x+2)=(x+2)
Now back to the problem!
x - 4 = 4x + 8
Solve for x to find out what the solution is.
Do this first by taking out the x
-4 = 3x + 8
subtract the 8
-12 = 3x
finally divide by 3
-4 = x
Tada!
Hope this helps!

Answer:
The y-value of Point A is 1.
Step-by-step explanation:
Because Point A only went up one (1) the coordinate plane.
