Answer:
they are opposites?
Step-by-step explanation:
2x makes x twice as big
while .5 makes x twice as small
not sure but thats what im thinkin
Answer: The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices.
Step-by-step explanation:
Substitution is a method of solving systems of equations by removing all but one of the variables in one of the equations and then solving that equation.
Elimination is another way to solve systems of equations by rewriting one of the equations in terms of only one variable. The elimination method achieves this by adding or subtracting equations from each other in order to cancel out one of the variables.
Augmented matrices can also be used to solve systems of equations. The augmented matrix consists of rows for each equation, columns for each variable, and an augmented column that contains the constant term on the other side of the equation.
First let's put them all over 100.

Then if we put them from least to greatest it would be from highest to lowest (since they are negatives)

<span>Kayla walks a path with a triangle shape with three corners, starting point A, point where turns north, B, and point where head towards start, C.
The question is calculate the angle in the point C, knowing that A-B distance is 4 km and B-C is 2.5
To do this calculation we are going to use the trigonometry function tangent:
tangent C = opposite/adjacent = 4/2.5 = 1.6
Then C angles is: C = arctan (1.6) = 57.99Âş
So the solution is round to 58Âş</span>
