The are formula for a triangle is (since a triangle is half a rectangle, and the area formula for a rectangle is b*h)
1/2 * b * h = area
Your equation would be:
1/2* 7.3 * 7 = area
=25.55
hope this helps! let me know if i am wrong!

<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
Step-by-step explanation:
According to the graph, our line's x-values span from -4 to infinity. Since -4 is closed dot, it is inclusive in the domain:
Interval Notation: [-4, ∞)
Interval Notation: y ≥ -4
