How do I evaluate an expression

1. Replace each variable in the expression with the assigned value.

2. Perform the operations in the expression using the correct order of operations.

Step-by-step explanation:

Here's an example. Let's evaluate the expression 2x³ – x² + y

for x = 3 and y = –2.

Replace each variable in the expression with its value. In this example, this means each x becomes a 3 and each y becomes a -2. (It's a good idea to use parentheses to keep track of this.)

So 2(3)³ - (3)² + (-2)

Perform operations with exponents.

2(27) - 9 + (-2)

Perform operations with multiplication and division.

54 - 9 +(-2)

Perform operations with addition and subtraction

I hope this helps!

Let me know if u have any questions :}

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
