Answer:
One
Step-by-step explanation:
It is given that,
y = 3x-5 ....(1)
y = -x+4 .....(2)
We can solve the above equations using substitution method. Put the value of y from equation (1) to equation (2) such that,
Put the value of x in equation (1) we get :
It means that the value of x is and the value of y is
. Hence, the given equations has only one solution.
Answer:
D.
Step-by-step explanation:
Remember that the limit definition of a derivative at a point is:
Hence, if we let f(x) be ln(x+1) and a be 1, this will yield:
Hence, the limit is equivalent to the derivative of f(x) at x=1, or f’(1).
The answer will thus be D.
