Answer:
Length of BC is 6.
Step-by-step explanation:
B is at (-2,-3) and C is at (4,-3)
Length BC

Answer:
-6.
Step-by-step explanation:
Difference coefficient
= -6(x + h) + 3 - (-6x + 3) / h
= -6x - 6h + 3 + 6x - 3 / h
= -6h / h
= -6.
Step-by-step explanation:
-(4x + 3x) = 10x - 5
We would have to multiply the -1 by the 4x and the 3x which is in the bracket.
Though there is no 1 behind the bracket but, behind any bracket there is 1 there even though it's ignored.
So when we multiply -1 by 4x we are going to get;
-4x
And when we multiply -1 by 3x It's going to be;
-3x
We have -3 and -4 because whenever we multiply any positive and negative number the product is negative.
So;
-4x - 3x = 10x - 5
So now, we group like terms;
- 4x - 3x - 10x = -5
So now that we have grouped, we have to add the negative numbers even though there is no addition sign there we would have to add
-17x = -5
So now we divide both sides by;
-17
Which is going to be;
x=
