Answer:
lets take a differential equation
taking derivative of M w.r.t y and N w.r.t x
so this is an in exact equation we will find integrating factor and make it exact equation
so 1/y is our integrating factor multiply it by the equation we will get an exact equation:
take derivative
now solving this exact equation
answer: 125 m²
i just took the question and it’s correct.
Substitute the linear eqn into quadratic, check discriminant
Answer: (0,-2)
Step-by-step explanation:
3x - 4y = 8
18x -5y = 10
-6(3x -4y)=8(-6)
-18x + 24y = -48
18x -5y = 10
19y= -38
y= -2
18x - 5(-2) =10
18x + 10 = 10
10 10
18x= 0
x= 0
Answer:2
Step-by-step explanation:
Given
The derivative of a function is
The slope at (2,9) is
the tangent at (2,9) is parallel to another tangent at (a,b) i.e. their slopes are equal
