To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

I hope this helps thank you

Help PLSSSSS BRAINLIST Rate of change on both of them pls look down below

expeople1 [14]

Answer:

$\huge \boxed{\mathrm{4}} \\ \huge \boxed{\mathrm{2}}$

Step-by-step explanation:

Rate of change is another term for the slope.

rate of change = slope = (change in y)/(change in x)

<u>Function A:</u>

y = mx + b (m = slope)

y = 4x - 3

Function A has a slope of 4.

The rate of change for function A is 4.

<u>Function B:</u>

Take two points.

(-1, 0) and (1, 4)

slope = (y2 - y1)/(x2 - x1)

slope = (4 -0)/(1 - -1)

slope = 4/2 = 2

The rate of change for function B is 2.

QveST [7]

Answer:

$82.31

Step-by-step explanation:

First, we need to find the total amount of money paid

$82 * 25 = 2050\\$

Next, add the new price for the new total

$2050 + 90 = 2160$

Now divide by total members (25 +1 = 26)

$2160 / 90 = $82.31$
