The "system" of equations can't be solved for (x, y), because there's no "system" of equations given. There's really only one equation.
Either of these two equations can be massaged to look exactly like the other one. And if you graph both equations, you find that they're both the same line on the graph.
ANY point on the line is a solution to both equations ... and we all know how many different points there are on a line.
7 quarts because 1 gallon is 4 quarts so 4•3=12 and 12-5=7 (Brainliest please)
The first column. The rule for that column is y = x * -4.
- Obtuse = one side is more than 90 degrees
- Acute = all sides are less than 90 degrees
- Isosceles = two sides are of the same length
- Equilateral triangle: all angles are of same measure (60)
- Scalene: all sides are of different lengths
- Right Triangle: One of the angles equals 90 degrees.
Answer:
Step-by-step explanation:
x+y = 60
x-y = 8
------------
2x = 68
x = 34
y = 60-x = 26
