Answer:
D. y-4= -3/2(x+5)
Step-by-step explanation:
Firstly, taking two valid ordered pairs from the graph:
(-2,4) and (2,-2)
Using Delta y over Delta x, we are able to obtain m as -3/2
Next,
The following is the point-slope formula:
y-y₁=m(x-x₁)
Based on the graph, (4,-5) can be spotted as a definite ordered pair
Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.
F(x). "f(x) = ... " is the classic way of writing a function. And there are other ways, as you will see! .... Example: {(2, 4), (2,5), (7,3)} is not a function because {2,4} and {2,5} means that 2 could be related to .

Answer:
24 cm
Step-by-step explanation:
Given: Picture of the star is made up of 4 unshaded equilateral triangles of equal area and a shaded square.
Area of the shaded region (square) = 
To find: the perimeter of the star
Solution:
Area of the shaded region (square) = 
Area of square = 

As each equilateral triangle has side lengths that are the same as the side length of the square,
length of side of the star = 3 cm
Perimeter is the sum of lengths of the sides.
Perimeter of star = sum of 8 sides of the star
= 8 × 3 = 24 cm
