If a b and c are three different numbers which of the following equations has exactly one solution?
Mrrafil [7]

Option B is correct.

Step-by-step explanation:

We need to identify which of the following equations has exactly one solution.

We will solve each equation to find the answer

A. ax+b=ax+b

Solving and finding value of x:

ax+b=ax+b\\ax-ax=b-b\\0=0

This equation has infinite number of solutions because both sides are equal to 0

B. ax=bx+c

Solving and finding value of x:

ax=bx+c\\ax-bx=c\\x(a-b)=c\\x=\frac{c}{a-b}

This equation has exactly one solution

C. ax+b=ax+c

ax+b=ax+c\\ax-ax=c-b\\0=c-b

This equation has no solution because both sides are not equal.

So, Option B is correct.

Dy/dx = (cos x) e^(y+sinx) and y = 0 when x = 0. find the original equation
Korvikt [17]
Find the general solution by separating the variables then integrating: 
dy / dx = cosx℮^(y + sinx) 
dy / dx = cosx℮ʸ℮^(sinx) 
℮^(-y) dy = cosx℮^(sinx) dx 
∫ ℮^(-y) dy = ∫ cosx℮^(sinx) dx 
-℮^(-y) = ℮^(sinx) + C 
℮^(-y) = C - ℮^(sinx) 
-y = ln[C - ℮^(sinx)] 
y = -ln[C - ℮^(sinx)] 

Find the particular solution by solving for the constant: 
When x = 0, y = 0 
-ln(C - 1) = 0 
ln(C - 1) = 0 
C - 1 = 1 
C = 2 
<span>y = -ln[2 - ℮^(sinx)]
