Answer:
7 radians
Step-by-step explanation:
In a circle, an angle measuring 2π radians intercepts an arc of length 14π. Find the radius of the circle in simplest form.
Since our Angle in in radians
The formula for Arc length = S = rθ
S = 14π
θ = central angle = 2π radians
Hence
r = S/θ
r = 14π/2π radians
r = 7 radians
Radius = 7 radians

y = 2x+5
x+3 = 2x+5
x+8 = 2x
x = 8
I think I did that right, anyway.
y=2x+5
1. Solve for the variable that is easiest to find.
In this case I will solve for x.
y=x+3
-3 -3
y-3=x
2. Now plug in (y-3) for x in the other equation.
y=2(y-3)+5 ~use distributive property
y=2y-6+5 ~combine like terms
y=2y-1
-2y=-2y
-y=-1 ~multiply both sides by -1
y=1
3. Since you have a value for y you can plug it in to solve for x.
y=x+3
1=x+3

'm' is for gradient of the line. First, calculate the gradient.
Let's use (6,15) and (8,21)
Gradient, m =
--------------
= 21 - 15 = 6 = 3
----------- ----
8 - 6 2
Therefore, m = 3 . Now let's search 'b' .
Let's use (6,15) again. Substitute it into the equation.
y=mx+b
15 = 3 (6) + b
b = -3
Thus, the equation : y=3x -3

Answer:
Step-by-step explanation:
x-intercept if when y is 0, so, on the x-axis. as we can see the x-intercept is -40
y-intercept if when x is 0, so, on the y-axis. as we can see the y-intercept is 15
Answer:
x-intercept:
y-intercept:
Step-by-step explanation:
The x-intercept is the point where the line meets the x-axis, and the y-intercept is the point on the line which meets the y-axis.
The line intersects the y-axis at , so the y-intercept is
.
The line intersects the x-axis at , so the x-intercept is
.
Hope this helps :)
