Answer:
Domain is all Real Numbers and the Range is all Real Numbers.
Step-by-step explanation:
It is a function.
The graph of this function is a straight line passing through the x axis at (10,0) and the y-axis at (0,10). The line continues to the left and right without bounds.
So the Domain is all Real Numbers and the Range is all Real Numbers.
The answer is 73.5
To make it a lot easier split the shapes into a rectangle and triangle.
The rectangle is a tad easier because the measurements are given here.
5 x 12 = 60 (rectangle area)
To find the triangle find the base then height. The base is 3cm and the height is 9cm (shown above)
9 x 3 = 27
Divide that by 2 because it's a triangle and you get 13.5.
Add those two numbers and voila you have your answer of 73.5.
A = -6
b = 48
Hope this helps :)
