Tao wants to check that the expression 3(4x – 6) simplifies to 12x – 18. What is the value when 2 is substituted for x into both expressions?
The value of each expression is 2.
The value of each expression is 6.
The value of one expression is 2, and the value of the other expression is 6.
The value of one expression is 6, and the value of the other expression is –6.

The value of each expression is 6.

Step-by-step explanation:

3(4x – 6)

Substituting 2 in for x

3(4*2 – 6)

Multiply first inside the parentheses

3(8-6)

Then subtract inside the parentheses

3(2)

Then multiply

6

Now check the second expression

12x-18

12*2 -18

24-18

6

Both expressions equal 6

The value of each expression is 6

Step-by-step explanation:

3(4x-6)

Substituting x for 2

3(4(2)-6)

3(8-6)

3(2)

3X2

=6

12x-18

Substituting x for 2

12(2)-18

24-18

=6

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
