The area of the triangle is 31.5 ft^2

Step-by-step explanation:

Mathematically, the area of the triangle is the product of the base and the height divided by 2

From the given diagram, the base is of the measure 4 ft + 5 ft = 9 ft

The measure of the height is 7 ft

Thus, we have the area of the triangle as;

1/2 * 7 * 9 = 31.5 ft^2

8 2/3 is the answer

step-by-step explanation: just use a calculator

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
