He may be wrong. If he was wrong, this is the example.
0 < -10x
If we were to divide both sides by -10, even though the answer would be undefined or just end up as zero, it is just a common rule to always flip the sign whenever you divide or multiply by a negative.
Don't quote me on it, but I think I'm right.
Hope this helped!
Answer:
7
Step-by-step explanation:
plug in 3 where ever there is x
so
(4(3)+2)-7
use PEMDAS to solve from left to right
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
so we got p so we do that first
(4(3)+2) --> 4 × 3 = 12 (Multiplication first like in PEMDAS)
(12+2) = 14
so then in the equation you are left with
(14)-7 = 7
answer is 7
Your domain is your x or x value. Therefore your domain should be 19; 20; 21; 22 and your y or y value is your range. Hope this helps
Answer:
see below
Step-by-step explanation:
The applicable rules of exponents are ...
- (a^b)(a^c) = a^(b+c)
- a^(-b) = 1/a^b
Using these to simplify your expression, you get ...
