Answer:
hello :
f(x) = 13/ (x-3)
f(x) exist : x - 3 ≠ 0
x - 3 = 0 : x = 3
the domain of the function : f is D = ]-∞:3[ U] 3;+∞[
2 would be the answer if you follow your order of operations the order of operations is parentheses exponents multiply divide whichever comes first and add and subtract whichever comes first and -6x with the exponent of 2 it can be turned into -36 cuz you're multiplying six two times then 8 * 4 is 32 and 3 * 6 is 18 so you would do -36 + 32 which would give you negative 4 then you're going to bring down the 18 then do -4 + 18 which would give you 4 then you're going to bring down the - 6 and do 4-6 and -6 -4 gives you positive 2
Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.
So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.
You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.
You get 3/1 × 1/1 = 3
It equals to 3
Then, 4(2.6) = 4 × 2.6 = 10.4
2(-3) = +2 × (-3) = -6
When you multiply a positive number for a negative one, you'll always get a negative number.
Sum all the results.
3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4
Final answer: -13,4
