4x+5y=20 in point slope form

Mathematics

Answer:

<em>y = </em>-\frac{4}{5}<em> x + 4 </em>

Step-by-step explanation:

<em>Ax + By = C is standard form of linear equation. </em>

<em>y - </em>y_{1}<em> = m( x - </em>x_{1}<em> ) </em>

<em>y = mx + b is slope intercept form of linear equation. </em>

<em>Thus, to write the point-slope equation we have to have the coordinates of the point that given line is passing through!</em>

I assume, that we have to re-write the standard form of linear equation into slope-intercept form. That's mean, we have to solve given equation for "y".

5y = - 4x + 20

<em>y = </em>-\frac{4}{5}<em> x + 4</em>

Answer:

y = -4/5x - 4

Step-by-step explanation:

y - y1 = m(x-x1)

4x + 5y = 20 ( subtract 4x on both sides)

5y = -4x + 20 (divide by 5 on each side)

y = -4/5x + 4

So we know one point is (0,4) y-intercept

now plug in (0,4)

y - 4 = -4/5(x-0) (Distribute -4/5 to x - 0)

y - 4 = -4/5x (now add 4 on each side)

y = -4/5x - 4

The value of a small airplane depreciates exponentially every year after it is purchased. The value, in thousands of dollars, a(
ratelena [41]

Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.

<h3>Exponential function:</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function for the value of the airplane after t years is given by:

A(t) = 131.5(0.8)^t

Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.
