Knowing the x intercept, we know that change in y / 4= a positive number for the slope. for points (...

I think the answer to the second Q is 6. Let's say R is a four digit number if R/10 =_ _ 3 _ with 3 in the tens place then multiplying it by 10 we get R in the hundreds place => R= _ _ 3 _ 0 Example: 630 X10= 6300 Secondly, if 10 R =_ 6 _ _ with 6 in the hundreds place, dividing by 10 gives us 6 in ...

Hence, sqrt 125 :sqrt 5 sqrt 25 :sqrt 5 dqrt. 5 :sqrt 5 thus, Square Root of 125= (Sqrt 5 X Sqrt 5) X (Sqrt 5) I only put the paranthesis to make you see it easier that Sqrt 5 X Sqrt5=5 The result of the simp...
