Here x1 = -5 , y1 = 0 , x2 = 4 and y2 = 3

equation of straight line

y - y1 = y2 - y1 / x2 - x1 (x - x1)

y - 0 = 3 - 0 / 4 + 5 (x + 5)

y = 3/9 ( x + 5)

9y = 3x + 15

3x + 15 - 9y = 0

Therefore 3x + 15 - 9y = 0 is requried answer.

Find the value of r so the line that passes through each pair of points has the given slope.
padilas [110]

Answer:

<em>- 4</em>

Step-by-step explanation:

( 3 - r ) / ( 1 + 5) = 7/6

\frac{3-r}{1+5} = \frac{7}{6} ⇒ 3 - r = 7 ⇒ r = <em>- 4</em>

The diameter of a circular chip is doubled to use in a new board game. The area of the new chip will be
nikitadnepr [17]

Answer: A_2=\frac{\pi(2D)^{2}}{4}


Step-by-step explanation:

1. You have the following formula for calculate the area of the original circular chip:

A_1=\frac{\pi(D)^{2}}{4}

Where D is the diameter of the circle.

2. Then, if the diameter of the original circular chip is doubled (2D) to use in a new board game, the area of the new chip can be calculated with the following formula:

A_2=\frac{\pi(2D)^{2}}{4}

Please help!<br> 5x^2 - 3x - 2 = 0<br> Solve using the zero-factor property.
Alex

Answer:

x = -2/5

x = 1

Step-by-step explanation:

5x² - 3x - 2 = 0

(5x + 2)(x - 1) = 0

⇒ 5x + 2 = 0

⇒ 5x = -2

⇒ x = -2/5

⇒ x - 1 = 0

⇒ x = 1

Which statement is true about the function f(x)= StartRoot negative x EndRoot?
UNO [17]

Answer:

The domain of the graph is all real numbers less than or equal to 0

Step-by-step explanation:

we have the function

f(x)=\sqrt{-x}

we know that

The radicand must be positive

so

-x \geq 0

Solve for x

Multiply by -1 both sides

x\leq 0

The domain is the interval ------> (-∞,0]

All real numbers less than or equal to zero

The range of the function is the interval -----> [0,∞)

f(x)\geq 0

see the attached figure to better understand the problem

All real numbers greater than or equal to zero

<em><u>Verify each statement</u></em>

case 1) The domain of the graph is all real numbers

The statement is false

Because, the domain is all real numbers less than or equal to zero

case 2) The range of the graph is all real numbers

The statement is false

Because, the range is all real numbers greater than or equal to zero

case 3) The domain of the graph is all real numbers less than or equal to 0

The statement is true

case 4) The range of the graph is all real numbers less than or equal to 0

The statement is false

Because, the range is all real numbers greater than or equal to zero
