Allow me to review before I start. Inconsistent means there's no solution to the system of simultaneous equations, i.e. parallel lines. Consistent means there's at least one solution. Independent and dependent apply to consistent systems. The former means exactly one solution (two lines in different directions which meet). Dependent means an infinite number of solution; the two lines are really the same line.
1. We have two different slopes, lines in two different directions, so they'll meet in exactly one place. That system is consistent and independent, the usual case.
2. We can write the first one y-3x= -2 and the second y-3x=+2. These are parallel lines that are different, so no solution: inconsistent.
3. The first equation is x+2y=4, same as the second. An infinite number of solutions. Consistent and dependent.
Answer:
448 units^2
Step-by-step explanation:
You need to find the area of each of the faces
1/2 * (7*24) = 84
1/2 * (7*24) = 84
5 * 25 = 125
5 * 24 = 120
5 * 7 = 35
Now add all these
448
The goal in rearranging equations to solve for y is to get y all by itself on one side.
Remember the order of operations.
PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)
When you isolate variables to solve for them, you'll do the order of operations in reverse.
