Answer:
2>y
Step-by-step explanation:
4/9>y/18
Here u cross multiple
4*18 >9*y
72>9y
the you divide both sides by 9
72/9>9y/9
8>y
Answer:
c=5
Step-by-step explanation:
Sorry I did a problem just like this on my paper so im just gonna copy my work
Simplifying
2x + -5 = 2x + -1c
Reorder the terms:
-5 + 2x = 2x + -1c
Reorder the terms:
-5 + 2x = -1c + 2x
Add '-2x' to each side of the equation.
-5 + 2x + -2x = -1c + 2x + -2x
Combine like terms: 2x + -2x = 0
-5 + 0 = -1c + 2x + -2x
-5 = -1c + 2x + -2x
Combine like terms: 2x + -2x = 0
-5 = -1c + 0
-5 = -1c
Solving
-5 = -1c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add 'c' to each side of the equation.
-5 + c = -1c + c
Combine like terms: -1c + c = 0
-5 + c = 0
Add '5' to each side of the equation.
-5 + 5 + c = 0 + 5
Combine like terms: -5 + 5 = 0
0 + c = 0 + 5
c = 0 + 5
Combine like terms: 0 + 5 = 5
c = 5
Simplifying
c = 5
Answer:
y = Ax^2
Step-by-step explanation:
below is the detailed solution
To determine the orthogonal trajectories of the family of curves
X^2 + 2y^2 = 17k^2
we have to differentiateX^2 + 2y^2 = 17k^2 with respect to x
= 2x + 4y dy/dx = 0
Hence : dy/dx = - x/2y
we have to determine the negative reciprocal
dy/dx = 2y/x ----------- 1
integrate equation 1
∫dy/2y = ∫dx/x
= 1/2 log y = log x + log c
log y = 2logx + 2logc
log y = logx^2 + logC^2
therefore : y = Ax^2 ; where C^2 = A
Because it is like a plane. In order to have a plane, there must be at least 3 points. In a chair with three legs, the legs are all in the same plane.
