Y=8/3x-5  my teacher want me to find the slope and y-intercept for each equation
Arte-miy333 [17]
Each of these equations follows the standard form: y = mx + b

The variable "m" is the slope, and the variable "b" is the y-intercept.

Therefore, with the equation y = 8/3x - 5, the slope ("m") would equal 8/3 and the y-intercept ("b") would equal -5

A rectangle patio has a perimeter of 38 feet. If the length of the patio is 5 feet less than twice the width, find the dimension
gayaneshka [121]

Answer:

The length is 11ft.

The width is 8ft.

Step-by-step explanation:

Hello!

Perimeter of a rectangle: P = 2(l + w)

  • P = perimeter
  • l = length
  • w = width

We know that the length is 5 ft less than twice the width, which can be expressed by the equation: l = 2w - 5. We can plug in 38 for "P".

We can substitute the equation for l, and solve for the width.

<h3>Solve for W</h3>
  • P = 2(l + w)
  • 38 = 2((2w - 5) + w)
  • 38 = 2(3w - 5)
  • 38 = 6w - 10
  • 48 = 6w
  • 8 = w

The width is 8. We can solve for the length by plugging it back into the equation l = 2w - 5

<h3>Solve for L</h3>
  • l = 2w - 5
  • l = 2(8) - 5
  • l = 16 - 5
  • l = 11

The length is 11.

The dimensions are 11 ft and 8 ft.
