Replace x with 2:

f(x) = 3x -12:

f(2) = 3(2) - 12

= 6 - 12

= -6

Answer:

  • \boxed{\sf{96x-70}}}

Step-by-step explanation:

Use the distributive property.

<h3>What is a distributive property?</h3>

Distributive property is a serving to distribute or allot or disperse.

<u>Distributive property:</u>

A(B+C)=AB+AC

A(B-C)=AB-AC

-10(1-9x)+6(x-10)

<u>Expand.</u>

-10(1-9x)

-10*1=-10

-10*9x=90x

\longrightarrow \sf{=-10+90x+6\left(x-10\right)}}

6(x-10)

6*x=6x

6*10=60

6x-60

<u>Rewrite the problem down.</u>

= -10+90x+6x-60

<u>Combine like terms.</u>

90x+6x-10-60

<u>Add the numbers from left to right.</u>

90x+6x=96x

96x-10-60

<u>Finally, subtract the numbers from left to right.</u>

-10-60=-70

\Longrightarrow \boxed{\sf{96x-70}}

Therefore, the final answer is<u> 96x-70.</u>

I hope this helps, let me know if you have any questions.
