How do you evaluate and interpret algebraic expressions? To evaluate an algebraic expression, substitute the value(s) of the (select) into the expression and simplify using the order of operations. To interpret an algebraic expression, identify the (select) of each (select) .

see explanation

Step-by-step explanation:

When you have an algebraic expression and you are required to evaluate the algebraic expression, all you need to do is to substitute the give values of each variable into the expression.

For instance, if you intend to evaluate 2x + 2 where x=2, all you need to do is to substitute 2 or x. That is 2(2) + 2=4

However, to interpret an algebraic expression, all you need to do is to identify all the terms and variables in the expression.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
