1 answer:
The coordinates plane is illustrated below.
<h3>How to illustrate the information?</h3>A coordinate plane simply means the graphing system for points and lines.
Based on the information given, the area of teb triangle will be:
= 1/2 × b × h
= 1/2 × 11 × 20
= 110
Other information are attached.

<h3>I'll teach you how to solve 11X - X2 +4y2 = 52</h3>
-----------------------------------------------------------
11X - X2 +4y2 = 52
Add similar elements:
9x+4*2y= 52
Multiply the numbers 4*2:
4*2= 8
9x+8y= 52
Subtract 8y from both sides:
9x+8y-8y= 52- 8y
Simplify:
9x= 52- 8y
Divide both sides by 9:
9x/9= 52/9 - 8y/9
Simplify:
x=
