Answer:
i)
ii) (f-g)(x)=2x-5
iii) (f+g)(-1)=3
Step-by-step explanation:
f(x)=3x+1
g(x)=x+6
we are asked to determine
i) (f.g)(x) = f(x).g(x)
ii) (f-g)(x)=f(x)-g(x)
=(3x+1)-(x+6)
=3x+1-x-6
(f-g)(x)=2x-5
iii) (f+g)(x) = f(x) + g(x)
= (3x+1)+(x+6)
= 3x+x+1+6
(f+g)(x)=4x+7
(f+g)(-1)=4(-1)+7
=-4+7
(f+g)(-1)=3
Answer:
5
Step-by-step explanation:
Let :
x(1) be 2
y(1) be 5
x(2) be -2
y(2) be 2
We know that distance between any 2 points is equal to:-
So using the above formula ,
Answer:
a=20; b=-12
Step-by-step explanation:
if you just say (20,-12) then a can anything it can be 20 or it can be -12 so (a=20; b=-12) is an organized way of keeping it.
