The function m is given in three equivalent forms. Which form most quickly reveals the zeros (or "roots") of the function? Choos

e 1 answer: (Choice A) m ( x ) = − 2 ( x − 6 ) 2 + 18 (Choice B) m ( x ) = − 2x^2 + 24x - 54 (Choice C) m ( x ) = − 2 ( x − 3 ) ( x − 9 ), Write one of the zeros

Answer:

Choice C

Step-by-step explanation:

Choice C already has X factored into a form which can readily be set equal to zero.

Eg. X - 3 = 0 and X - 9 = 0

To find the zeroes, simply solve for X

Fill in the blank with a constant, so that the resulting expression can be factored as the product of two linear expressions: 2a
Vitek1552 [10]

Answer:

2ab - 6a + 5b - 15

Step-by-step explanation:

Given

2ab - 6a + 5b + \_

Required

Fill in the gap to produce the product of linear expressions

2ab - 6a + 5b + \_

Split to 2

(2ab - 6a) + (5b + \_)

Factorize the first bracket

2a(b - 3) + (5b + \_)

Represent the _ with X

2a(b - 3) + (5b + X)

Factorize the second bracket

2a(b - 3) + 5(b + \frac{X}{5})

To result in a linear expression, then the following condition must be satisfied;

b - 3 = b + \frac{X}{5}

Subtract b from both sides

b - b- 3 = b - b+ \frac{X}{5}

- 3 = \frac{X}{5}

Multiply both sides by 5

- 3 * 5 = \frac{X}{5} * 5

X = -15

Substitute -15 for X in 2a(b - 3) + 5(b + \frac{X}{5})

2a(b - 3) + 5(b + \frac{-15}{5})

2a(b - 3) + 5(b - \frac{15}{5})

2a(b - 3) + 5(b - 3)

(2a + 5)(b - 3)

The two linear expressions are (2a+ 5) and (b - 3)

Their product will result in 2ab - 6a + 5b - 15

<em>Hence, the constant is -15</em>

Find the center and raduis of the circle
posledela

Answer:

B

Step-by-step explanation:

Because the equation can be written in the form (x-p)^2+(y-q)^2. So it represents a <u>circle</u> with the radius r=3 and the center of (5,0).
