Select True or False. The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x. True False
To figure this out, you need to distribute the 2 in the first equation and solve for any like terms. Once you solve the first equation, compare it with the second one and see if they are equivalent.
idk how to do that
To distribute the 2, multiply 5x times 2 and -1 times 2. Then you will get 4x - 10x - 2. Then you combine like terms: 4x - 10x= -6x, so your equation becomes -6x - 2.
So that means the first expression is equivalent?
Well both the 2 and 6x are negative in the first expression and positive in the second, so what do you think?
No?
No, I don't think they are equivalent.
you were right thank you
can you help me with another
Simplify negative 6 over 3 divided by 2 over negative 9. 9 11 12 18
so you mean (-6/3)/(2/-9) ?
When dividing a fraction by another fraction, you invert the second one (switch the numerator and denominator) and multiply. So it becomes (-6/3) x (-9/2)
Then you multiply the -6 times -9 = 54 and 3 times 2 = 6. So then you have 54/6, which reduces to become 9.
