2x-3y+7=0 -- add 3y to both sides
3y=2x+7 -- divide by 3
y=2x/3 +7/3
The gradient is 2/3
Jamestown- Why are there positive and negative interactions when cultures meet?
Answer:
37.9 cm
Step-by-step explanation:
Arc length is:
s = 2πr (θ/360°)
where r is the radius and θ is the arc angle.
40π cm = 2πr (190°/360°)
20 cm = r (190°/360°)
r = 37.9 cm
The value of n is 4 and yz is 1 if y is between x and z i.e. if y, x and z are collinear points.
According to the given question.
We have some linear equations.
xy = 4n + 3
yz = 2n - 7
and
xz = 20
Since, y is between x and z. Which means y, x and z are collinear points.
Therefore,
xy + yz = xz
⇒ 4n + 3 + 2n - 7 = 20
⇒ 6n -4 = 20
⇒ 6n = 20 + 4
⇒ 6n = 24
⇒ n = 24/6
⇒ n = 4
Therefore,
yz = 2n - 7 = 2(4) - 7 = 8- 7 = 1
Hence, the value of n is 4 and yz is 1 if y is between x and z i.e. if y, x and z are collinear points.

Answer:
12
Step-by-step explanation:
The circumference of a circle is given as
Circumference = 2πr
Where; r is the radius of the circle
The diameter of a circle is 2 times the radius of that circle. It cuts the circle into 2 equal halves
Given, circumference of the circle = 12π
12π = 2πr
make r the subject by dividing both sides by 2π
12π/2π = 2πr/2π
r = 6
Diameter = 2r
= 2 X 6 = 12
