Consider the expression 5x + 10. Is the expression a numerical expression or an algebraic expression? How do you know?
How many terms are in the expression?
If there is a variable, what is the coefficient on the variable?
Write the expression using words.

Step-by-step explanation:

=> It is an algebraic expression.

=> There are 2 terms 5x,10.

=> Yes,there is a variable X the coefficient is 5.

=> Expression in words = Five times X plus ten.

Hope this helps you.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
