1 is the simplest form since the line means division. 54 divided by 54 is 1.
You can graph them on Desmos, then use this attachment to find out the classification.
In the first system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.
In the second system, they're parallel lines with no solution, therefore the answer is inconsistent.
In the third system, they intersect and they have one solution, therefore the answer is consistent, independent.
In the fourth system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.
Answer:
15° C.
Step-by-step explanation:
To do this, we will need to plug in and solve.
59 = 9/5c + 32
Isolate the variable by subtracting 32 by both sides:
27 = 9/5c.
Divide both sides by 9/5, giving you:
15° C.
Answer:
b.
Step-by-step explanation:
Two supplemental angles add up to 180°
So we have (A + B = 180°)
The measure of one of them is always 180° - the other.
A = 180° - B
B = 180° - A
