I think that she could buy 3 tubes of paint because that's $25.50 and that gives you 28.50 for the canvas.
It is called the slope of the line
Answer:
=21+11x
Step-by-step explanation:
Answer: 36 units squared.
Explanation:
Area of a traingle is given by,
| 0.5{x1(y2-y3) + x2(y3-y1) + x3(y1-y2)} |
Accepting the values of the coordinates in x's and y's,
x1 =0, y1=0
x2=3, y2=8
x3 =9, y3=0
= | 0.5 × (-72)|
= 36 unit squared.
