(3,4)  (9,7)

to find the slope

m = (y2-y1)/(x2-x1)

  = (7-4)/(9-3)

3/6

1/2

The slope is 1/2

point slope form

y-y1 = m(x-x1)

y-4 = 1/2(x-3)

distribute

y-4 = 1/2x -3/2

add 4 to each side

y = 1/2 x -3/2 + 4

y = 1/2 x -3/2 + 8/2

y = 1/2 x + 5/2

this is in slope intercept form

y = \frac{1}{2} x + \frac{5}{2}

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 4 ) and (x₂, y₂ ) = (9, 7 )

m = \frac{7-4}{9-3} = \frac{3}{6} = \frac{1}{2}

y = \frac{1}{2} x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 4 ) then

4 = \frac{3}{2} + c ⇒ c = \frac{5}{2}

y = \frac{1}{2} x + \frac{5}{2} ← equation in slope-intercept form

What is the simplified form of √144x^36
Nadusha1986 [10]

Answer:

The simplified form of \sqrt{144x^{36}} is 12x^{18}

Step-by-step explanation:

Given : \sqrt{144x^{36}}

We have to write the simplified form of \sqrt{144x^{36}}

Consider the given expression \sqrt{144x^{36}}

We know \sqrt{144}=12

and \sqrt{x^{36}}=\sqrt{x^{18}\cdot x^{18}}

Thus,

\sqrt{144x^{36}}=\sqrt{12^2\cdot (x^{18})^2}

Simplify, we have,

=\sqrt{12^2\cdot (x^{18})^2}=12x^{18}

Thus, The simplified form of \sqrt{144x^{36}} is 12x^{18}

The zeros for f(x)=x^4-4x^3-9x^2+36x are
Mrrafil [7]
X^4 - 4x^3 - 9x^2 + 36x = 0
 x(x^3 - 4x^2 - 9x + 36) = 0
x(x^2(x - 4) - 9(x - 4) = 0
x(x + 3)(x - 3)(x - 4) = 0

the zeroes are  -3, 0, 3, 4  Answer
