Answer:
With given side lengths a triangle <u>could not</u> be created.
Step-by-step explanation:
Given:
First side length = 7.7 cm
Second side length = 4.0 cm
Third side length = 1.7 cm
We need find whether this could be the side length of the triangle.
Solution:
Now we know that;
By Triangle In equality property which states that;
"Sum of the two side length of the triangle must be greater than third side."
It should fulfill all three conditions;
So we will find the same.
Condition 1:
First Side + Second Side > Third side
Hence This condition is true.
Condition 2:
Second side + Third Side > First side
Hence This condition is False.
Condition 3:
First side + Third Side > Second side
Hence This condition is true.
Since One of the condition is false hence With given side lengths a triangle could not be created.
Answer:
The inverse is g(x)=-x+5.
Both f and g have domain and range all real numbers.
In interval notation that is
Step-by-step explanation:
f(x)=-x+5 is a linear function.
Since isn't f(x)=constant then it is diagonal so this means the range is all real numbers.
For any linear function, the domain will be all real numbers.
So to find the inverse of y=-x+5, you interchange x and y and resolve for y.
y=-x+5
(interchange)
x=-y+5
(solve for y)
Subtract 5 on both sides:
x-5=-y
Multiplying both sides by -1:
-x+5=y
So the inverse is g(x)=-x+5. To find find the domain and range of the inverse function given you already did it for the original function, the sets are swapped. The sets were the same here because they were both all real numbers.
