Best ResponseYou've already chosen the best response.2I suppose that should give you something like 2*(3) = 2*(x)  3(x3) can you solve for x from there? :)

Best ResponseYou've already chosen the best response.2try plugging it back into the original stufff if there's problems with it > extraneous if it comes out to be true (like 3=3) then > non extraneous

Best ResponseYou've already chosen the best response.2to get the inverse of a function, you flop the x and y and solve for the new y \[x = \frac{ 5y  3 }{ 4 }\]now try to get y alone ^_^

Best ResponseYou've already chosen the best response.0Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x)= −1x + 1 The function g of x going through 0, 3 and 2, negative 1 The function f(x) has a larger slope. The function g(x) has a larger slope. They both have the same slope. The relationship between slopes cannot be determined.

Best ResponseYou've already chosen the best response.2ew the wording of this is weird do they mean larger as in slope of 2 is greater than slope of 1 because it is steeper? or do they mean larger as in 1 is greater than 2 because it is?

George − 3x − 30 = 5x + 18 − 3x − 30 − 5x = 5x + 18 −5x −8x − 30 = 18 − 8x − 30 + 30 = 18 + 30 −8x = 48 Negative 8x over negative 8 equals 48 over negative 8 Bella x = − 6 − 3x − 30 = 5x + 18 −3x − 30 − 3x = 5x + 18 − 3x − 30 = 2x + 18 −30 − 18 = 2x + 18 −18 − 48= 2x Negative 48 over 2 equals 2x over 2 x=−24 Bella made the error when she subtracted 18 Bella made the error when she subtracted 3x George made the error when he subtracted 5x George made the error when he divided by −8

Best ResponseYou've already chosen the best response.2good! now the big fraction line can be interpreted as a division sign and dividing is just multiplying by the flipped so x^2 + 5x +6 5 x^2 y  *  15 x y^2 2x^2 + 7x + 3

Best ResponseYou've already chosen the best response.0yeah will is be (x + 3) (x + 2) and (x + 3) (2x + 1) and since we have both of (X + 3) would it be \[\frac{ x + 2 }{ 15xy^2 } \times \frac{ 5x^2y }{ 2x +1 }\]
