Answer:
Step-by-step explanation:
(x - 4)
What you are being asked to do is find the exact same binomial in the top as is in the bottom.
But there's a small catch. You must stipulate that x cannot equal 4. If it does, then you will get 0/0 which is undefined. You can't have that happening -- not at this level.
Any other value for x is fine.
Answer: B
Step-by-step explanation:
2/3 x 2/1 =4/3
Answer: D
Step-by-step explanation:
10 squared is 100 and 11 squared is 121, and 111 is in between those two numbers.
F(x) = | 4x - 1 | .....when f(x) = 7
7 = | 4x - 1 |
4x - 1 = 7 -(4x - 1) = 7
4x = 7 + 1 -4x + 1 = 7
4x = 8 -4x = 7 - 1
x = 8/4 -4x = 6
x = 2 x = -6/4
x = - 3/2
solutions are x = -3/2, 2
