Answer:
- no solutions
- a finite number of solutions
- an infinite number of solutions
Step-by-step explanation:
Your question is very general, including linear and non-linear equations of any number and/or degree. In the general case you're asking about, there will be ...
- no solutions -- no values of the variables satisfy all equations
- a finite number of solutions -- all equations are satisfied for some finite set of variable values
- an infinite number of solutions -- equations are dependent (or periodic*) so the set of solutions is an infinite set
__
For 2 linear equations in 2 unknowns, there will be 0, 1, or infinite solutions.
_____
* Aperiodic equations may also have an infinite number of solutions. 1/sin(x)=0 is an example.
Answer:
Step-by-step explanation:
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1)
so it would be
11-(-1)/12--4)
which would be
12/16
to simplify that it is 3/4
Answer:
50 newspapers
Step-by-step explanation:
100 (total amount of newspapers) - 25 (amount Edward already sold) = 75 (amount of newspapers left)
75 (amount of newspapers left) ÷ 3 (Edward and his 2 friends) = 25 (equal amount each person delivered)
25 (amount Edward already sold) + 25 (amount Edward sold after his friends helped him) = 50 (amount of newspapers Edward sold in total)
Answer:
x(x + 4) = 21
Step-by-step explanation:
Area = length * width.
21 = x + 4 * x
x(x + 4) = 21
