For starters, follow through this problem on the order of operations. PEMDAS is the one I use, but I’ve seen others. It stands for Parenthesis Exponents Multiplication Division Addition Subtraction. You can’t do anything inside the parenthesis and there are no exponents, so we skip to the multiplication. That -2 outside of the parenthesis is what you multiply by. So, your equation then becomes 7x -6x +12. Combining like terms, you are left with x + 12. If what are looking for is substituting -3 in for x, that’s also easy. Just put -3 in place of all the x’s and again follow through order of operations. 7(-3)-2[4(-3)-6] is what you should start off looking like. Doing your multiplication, you have -21 -2(-12-6). Go to your parenthesis, -21 -2(-18). Multiply, -21 + 36. And finally, add. If using substitution, your answer is 15. I did both equations because I didn’t know which way they were supposed to be drone because that x= -3 thing was confusing me. I hope this helped though. :)

Write the function notation for the transformation that would change f(x) to have a vertical
koban [17]

Function is 4 - \frac{f(x)}{8}.

<u>Step-by-step explanation:</u>

We have a function notation for the transformation that would change f(x) to have a vertical  compression by a factor of \frac{1}{8}, reflection over the x axis, up 6 and right 2.

<u>Step 1:</u>

Vertical compression by a factor \frac{1}{8} , this means decreasing value of function by a factor of  \frac{1}{8}. Function becomes \frac{f(x)}{8}.

<u>Step 2:</u>

Reflection over x-axis means rotating f(x) by 180° over origin . Function now is -\frac{f(x)}{8}.

<u>Step 3:</u>

Up 6 , means value of function is increased by 6 , Function now is \frac{-f(x)}{8}  + 6.

<u>Step 4:</u>

Right 2, means shifting function to 2 units on right side i,e, on x-axis.

∴Function finally becomes, \frac{-f(x)}{8} +6 - 2 which is 4 - \frac{f(x)}{8}.

Can someone please answer. There is one question. There a picture. Thank you!

Ok so you need the surface area formula of a cone.

A = πrl +  πr∧2

where π = 3.14 (pi) 
           r = half of the diameter (18/2 = 9)
           l = slant hight ( 22 )
Slot this into the equation  A =  (3.14 [ rounded] )(9)(22) + (3.14 [ rounded] )(9)∧2 = 876.06 this is due to the rounded pi the answer is 876.5 i.e the third.

Hope this helps :D.
