Answer:

A) - 2a+3b

B) 1.2a+1.2b

OP = OA + AP

AP:PB = 2:3

So, AP is 2/5 of AB

2/5 is the same as 0.4

OA+AP

2a + 0.4AP

2a + 0.4(-2a+3b)

2a + - 0.8a + 1.2b

1.2a + 1.2b

For B:

I don't know how to find the multiple of a+b to OP, for the last mark, but I hope this helps!

Finding the domain of a rational function. <br><br> F(x)=x/x^2-4
sleet_krkn [62]
If the equation is x/(x^2-4) then I will solve it here

it's rational
therefor we can't have any impossibles like dividing by zero and square root of -1 an d stuff



f(x)=x/(x^2-4)

we know that the denomenator cannot be equal to zero so the numbers you cannot user are the numbers that will make the bottom number zero
so x^2-4=0
x^2=4
x=-2 or 2

so x cannot be -2 or 2, but it can be all other numbers so
domain=all numbers except -2 and 2
