we have
-----> equation A
----> equation B
To find the solutions for x of the system of equations
equate equation A and equation B
The values of x of the intersection points are the solutions of the system
Using a graphing tool
see the attached figure
There are two intersection points
therefore
The solutions are

Answer:
14 feet
Step-by-step explanation:
Let the shorter piece have length x.
Since the ratio is 2:3 and the longer piece is 21 feet long, we can write that as 2:3 = x:21.
Writing it as fractions, we get 2/3 = x/21 —(multiply by 21)—> x = 21*2/3 = 7*2 = 14 feet.
Thus, the shorter piece is 14 feet.
I hope this helps! :)
PEMDAS order refers to parentheses, exponents, multiplication, division, addition, and subtraction. So, 2*5=10 and 34+10=44.
