Perimeter is adding the 3 sides together. Since both triangles have the same perimeter set both triangles to equal:
(x+3 + x+3 + x+3) = (x+3 + 2x-3 + x)
Simplify each side:
3x+9 = 4x
Subtract 3x from each side:
x=9
1 Correct!
2 Correct!
3 Correct!
4 Correct!
5 Correct!
The inverse variation of y=3 would be y=1/3
The inverse variation of x=5 would be x=1/5
You just need to flip the variation around.
Your answer is: y=1/3; x=1/5
Have an amazing day and stay hopeful!
Answer:
b - (-2,-1)
Step-by-step explanation:
A function is a mapping in which each element of the domain, or input, is mapped to one element of the range, or output.
In this mapping, the input value -2 is mapped to both 2 and -1; this makes the points (-2, 2) and (-2, -1). If one of these two was removed, the mapping becomes a function.
The only one of these listed in the values given is (-2, -1).
