Determine the y-intercept of the line that passes through (-5,-12) and has a slope of -5
brilliants [131]

Answer:

-37

Step-by-step explanation:

Not sure what the method is called, but you do this.

substitute the slope into slope formula

y= -5x+b

substitute the points you have for x and y

-12= -5(-5)+b

solve

-12= 25+b

-37= b

If 5-y^2=x^2 then find d^2y/dx^2 at the point (2, 1) in simplest form. ​
ratelena [41]

Answer:

y"(2, 1) = -5

Step-by-step explanation:

Step 1: Define implicit differentiation

5 - y² = x²

Step 2: Find dy/dx

  1. Take implicit differentiation: -2yy' = 2x
  2. Isolate y': y' = 2x/-2y
  3. Isolate y': y' = -x/y

Step 3: Find d²y/dx²

  1. Quotient Rule: y'' = [y(-1) - y'(-x)] / y²
  2. Substitute y': y" = [-y - (-x/y)(-x)] / y²
  3. Simplify: y" = [-y - x²/y] / y²
  4. Multiply top/bottom by y: y" = (-y² - x²) / y³
  5. Factor negative: y" = -(y² + x²) / y³

Step 4: Substitute and Evaluate

y"(2, 1) = -(1² + 2²) / 1³

y"(2, 1) = -(1 + 4) / 1

y"(2, 1) = -5/1

y"(2, 1) = -5

the length of a rectangle is 9 inches less than twice the width. if the perimeter of the rectangle is 84 inches, find the dimens
Alexus [3.1K]

translate each statement into mathematical language

 

length is nine inches less than twice width.    L = 2W - 9

perimeter is 84 inches                                   2L +2W = 84

 

Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing

 

2(2W-9) + 2W = 84

 

4W - 18 + 2W = 84

 

(4W+2W) = 84+18  

6W =  102

W = 102/6 = 51/3

 

L = 2(51/3) - 9

= L= 17-9

L=6
