Answer:
1. 89/112 2. 32/39
Step-by-step explanation:
<u>Answer</u>
1st number = x
2nd number = 4x
3rd number = x + 100
sum of three numbers = 592
x + 4x + x + 100 = 592
6x + 100 = 592
6x = 592 - 100
6x = 492
x = 492/6
x = 82
1st number, x = 82
1st number, x = 822nd number, 4x = 328
1st number, x = 822nd number, 4x = 3283rd number, x+100 = 182
check :
82 + 328 + 182 = 592
pls mark as brainliest. . . ☺
The answer is 6 months because $1100 - $200 (which he already has) = $900. $900 divided by $150 (which he saves each month) = 6. So it took him 6 months to save up enough.
Answer:
Step-by-step explanation:
Given a curve defined by the function 2x²+3y²−4xy=36
The total differential of this function with respect to a variable x makes the function an implicit function because it contains two variables.
Differentiating both sides of the equation with respect to x we have:
4x+6ydy/dx-(4xd(y)/dx+{d(4x)/dx(y))} = 0
4x + 6ydy/dx -(4xdy/dx +4y) = 0
4x + 6ydy/dx - 4xdy/dx -4y = 0
Collecting like terms
4x-4y+6ydy/dx - 4xdy/dx = 0
4x-4y+(6y-4x)dy/dx = 0
4x-4y = -(6y-4x)dy/dx
4y-4x = (6y-4x)dy/dx
dy/dx = (4y-4x)/6y-4x
dy/dx = 2(2y-2x)/2(3y-2x)
dy/dx = 2y-2x/3y-2x proved!
