The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
Answer:
We can not see all the graphs, so i will just do a graph of the system of inequalities, and you can select the option that matches it.
We have the system:
y ≥ 2x + 1
(to represent this, we need to have a solid line y = 2x + 1, and shade all the region above this)
y ≤ 2x - 2
(to represent this, we need to have a solid line y = 2x - 2, and shade all the region below this)
The graph of this system is shown below:
If I could look at the graph and it would really help....
Answer:
60.39 inches
Step-by-step explanation:
Given that:
A Pac-Man poster which is having three fourth of a circle and there are two sides.
Diameter of circle = 18 inches
Sides of Pac-Man poster = 9 inches
To find:
Perimeter of the Pac-Man poster.
Solution:
Perimeter of a figure is nothing but equal to the periphery i.e. the outer area of the circle/figure.
Perimeter of a circle is given by the formula:
Perimeter =
is the radius of the circle.
Radius is half of perimeter.
Perimeter of the Pac-Man poster = Perimeter of circle + 2 sides
Perimeter of the Pac-Man poster = + 9+9 = 42.39+28 = <em>60.39 inches</em>
