Remember
\sqrt{ab}=(\sqrt{a})(\sqrt{b})

so

\sqrt{27a}=(\sqrt{27})(\sqrt{a})=
(\sqrt{(3)(3)(3)})(\sqrt{a})=
(\sqrt{(3)(3)})(\sqrt{3})(\sqrt{a}=
(3)(\sqrt{3})(\sqrt{a})=
(3)(\sqrt{3a})=
3\sqrt{3a}

You split a square root into two square roots if it is not a prime number.

\sqrt{ab} = \sqrt{a}\sqrt{b}

Find two factors where one is a perfect square.

\sqrt{27a} = \sqrt{3a}\sqrt{9} = 3\sqrt{3a}

What is the slope intercept form of the equation of the line?
beks73 [17]

Answer:

The slope-intercept form of the equation of the line is:

y = 2/3x + 2

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the points

  • (0, 2)
  • (3, 4)

(x₁, y₁) = (0, 2)

(x₂, y₂) = (3, 4)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [4 - 2] / [3 - 0]

               = 2 / 3

Thus, the slope of the line = m = 2/3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept b = 2

now substituting m = 2/3 and b = 2 in the slope-intercept form

y = mx+b

y = 2/3x + 2

Therefore, the slope-intercept form of the equation of the line is:

y = 2/3x + 2

Help with this question please?

Answer:

  x^2/25 +y^2/9 = 1

Step-by-step explanation:

You can think of an ellipse as a circle with a different scale factor in the x-direction than in the y-direction. When either dimension is stretched by a factor of k, the corresponding variable (v) is replaced by (v/k).

Here, the unit circle

  x^2 +y^2 = 1

is stretched by a factor of 3 vertically (in the y-direction) and a factor of 5 horizontally (in the x-direction). That means we can replace x with (x/5) and  y with (y/3) in the above equation to get ...

  (x/5)^2 +(y/3)^2 = 1

Traditionally, the denominator is written as a number, not a square, so the equation would be ...

  x^2/25 +y^2/9 = 1
