Zeros are

  • (0,0)
  • (-3,0)
  • (-4,0)

Write in factor form and solve

  • (x-0)(x-(-3))(x-(-4))=0
  • x(x+3)(x+4)=0
  • x[x(x+4)+3(x+4)]=0
  • x(x²+4x+3x+12)=0
  • x(x²+7x+12)=0
  • x³+7x²+12x=0

Points given (-2,16)

Solve for n

  • n(x³+7x²+12x)=y

On solving we get

  • n=-4

So the function is

  • y=-4(x³+7x²+12x)
  • y=-4x³-28x²-48x

Answer:

-4x³ - 28x²- 48x

Explanation:

  • x-intercept: (-4, 0), (-3, 0), (0, 0)

→ so equation: a(x+4)(x+3)(x+0)

  • point given: (-2, 16)

→ substitute these points to find <u>a</u>

  • a(-2+4)(-2+3)(-2) = 16
  • a = -4

so the graphed cubic equation:

  • -4(x+4)(x+3)(x+0)
  • -4x³ -28x²-48x

105 + 35m = expression . Apply the distributive property and the greatest common factor to write an equivalent
andrey2020 [161]

Answer:

<h2>35 × (3 + m)</h2>

Step-by-step explanation:

The distributive property:

<em>a × (b + c) = a × b + a × c</em>

105 = 35 × 3

35m = 35 × m

105 + 35m = 35 × 3 + 35 × m = 35 × (3 + m)

emmainna [20.7K]

Answer

The owner lose is $100 .

Reason

As given

A man comes into a store and steals $100 from the register without the owner knowledge.

Comes back and buys $70 worth of stuff and the owner gives him $30 in change.

i.e First man steals $100  than give back to owner when he buys  $70 worth of stuff and  the owner gives him $30 in change.

Therefore the total owner lose is the sum of  $70 worth of stuff and  $30 in change.

Total owner lose = $70 + $30

                            = $100

Therefore the owner lose be  $100 .

Hence proved
