Slope of the linear equation 4x = 2y - 3 is ____.

Anettt [7]

Answer:

Step-by-step explanation:

we want y = mx + b

4x = 2y - 3

-2y = -4x - 3

2y = 4x - 3

therefore the gradient (slope) = the coeffecient of x, which in this case is 4

Answer:

Perimeter of the sector = (36 + 8π) cm.

Step-by-step explanation:

Formula to find the of an arc of the circle is,

Length of the arc = $\frac{\theta}{360}(2\pi r)$

Here, θ = central angle formed by the arc

r = radius of the circle

Therefore, length of the arc given in the picture = $\frac{80}{360}(2\pi) (18)$

= 8π cm

Perimeter of the sector = Sum of all sides of the sector

= Length of radius + length of the arc + length of radius

= 18 + 8π + 18

= (36 + 8π) cm

Perimeter of the sector is (36 + 8π) cm.
