4(3b - 5) < -31 + 12b
12b - 20 < -31 + 12b, this is not true because -20 > - 31, so that the solution for the given inequality does not exist.
Seven minus negative two times negative 4 is equal to -1
Simple math rules state that a negative times a negative equals a positive!
Three times negative 2 minus three is equal to -9
you get a negative
(9 - y)(a + 5)
Positive (Plus) times Negative (Minus) always equals a negative (minus).
The quotient of a positive integer by a negative is always negative. Say this to yourself a couple times: "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
Seven minus negative two times negative 4 is equal to -1
Simple math rules state that a negative times a negative equals a positive!
Negative times positive equals negative.
I honestly don't know :D but heres something to help you "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
Three times negative 2 minus three is equal to -9
negative 49. This is because a minus multiplied by a plus is a minus.
you get a negative
Your answer will depend on the parameters of the instructions. If you're looking for the first derivative, simply use the product rule by changing the denominator to a negative exponent and bringing it up (take the negative square root of the quantity x-2 to the top). Then, follow the rules of calculus and algebra. Wow, that's a mess. Let's see... you get "the quantity x cubed plus 6x squared plus 3x plus 1 times the quantity -1(x-2) raised to the negative second plus the quantity x-2 raised to the negative first times the quantity 3x squared plus 12x plus 3." This is because of the Product Rule. Simplifying (by factoring out (x-2) raised to the negative second and combining like terms) gives us "(x-2) raised to the negative second times the quantity 2x cubed minus 24x minus 7." This can also be written as "2x cubed minus 24x minus 7 all over the quantity x-2 squared." f'(x)= 2x^3-24x-7 (x-2)^2
Negative times a Negative is a Positive. Negative minus a Negative is a Negative.
