11) 7 + -10+(4(5+-3)) = 7+-10+8=5

12) (12 +-10)+3x+-1(2x+4x), 12+-10x+3x+-2x+-4x = 12+-13x

11. According to the Order of Operations, you start with the inner brackets and work outward. Then, finally, you do the sum left to right.

... 7 + (-10) +(4(5 -3))

... = 7 + (-10) +4(2)

... = 7 + (-10) + 8

... = -3 + 8

... = 5

12. (12 -10x) +3x -(2x +4x)

... = (12 -10x) +3x -6x . . . . . . combine terms inside parentheses

... = 12 - 10x + 3x - 6x . . . . . terms inside the left parentheses cannot be combined

... = 12 -7x -6x . . . . . . . . . . . here, we're combining terms left to right. Of course like terms can be added in any order you may desire, as long as you pay attention to signs. It is sometimes convenient to add all the positve terms, add all the negative terms, then find the sum of those. -10x +3x -6x = 3x -(10x +6x) = 3x -16x = -13x.

... = 12 -13x

Answer:

g(3) = 6

Step-by-step explanation:

The right side of the equation is the part with all the information for the doing of the math.

x^2 - 3 means square the number and then subtract 3.

On the left side of the equation is the g(x). g(x) or f(x) or k(x) is literally just y. Someone could ask what is f(x)? It is y.

What is g(x)? It is y.

What is g? It is the name of the function. So instead of saying ..."the thing where you square a number and then subtract 3..." you can just say "g". Now the (x) beside g DOESNOT mean times, bc sometimes parenthesis means times. THIS IS NOT TIMES!

The (x) is like a billboard. Tells you who will be starring as x in the work on the right side of the equation.

If you see g(x)=x^2-3

then whatever is in the ( ) on the left, put that in the place of x on the right.

g() = ^2 - 3

g(12) = 12^2 - 3

g(-7) = (-7)^2 - 3

or like your question

g(3) = 3^2 - 3

do the calculation

g(3) = 9 - 3

g(3) = 6

done! Hope this helps!
