<em>given</em>

y + 2 = - 3/2 ( x + 2 )

<em>distribute</em>

y + 2 = - 3/2x + 3

<em>subtract 2 from both sides</em>

y + 2 = - 3/2x + 3

...

y = - 3/2x + 3 - 2

<em>combine like terms</em>

y = - 3/2x + 1

answer:

y = - 3/2x + 1

the slope is - 3/2

the y intercept is + 1

Answer:

9.4m is the answer.

Step-by-step explanation:

a = 8m

b = 5m

c = ?

According to the Pythagoras theorem,

a² + b² = c²

8² + 5² = c²

64 + 25 = c²

89 = c²

c = 9.433

Rounding off,

c = 9.4m

which of the following expresses the coordinates of the foci of the conic section shown below? (x-2)^2/4+(y+5)^2/9

elena55 [62]

Step-by-step explanation:

$\frac{(x - 2) {}^{2} }{4} + \frac{(y + 5) {}^{2} }{9} = 1$

This is the equation of the ellipse. Since the denominator is greater for the y values, we have a vertical ellipse. Remember a>b, so a

The formula for the foci of the vertical ellipse is

(h,k+c) and (h,k-c).

where c is

Our center (h,k) is (2, -5)

${c}^{2} = {a}^{2} - {b}^{2}$

Here a^2 is 9, b^2 is 4.

${c}^{2} = 9 - 4$

${c}^{2} = 5$

$c = \sqrt{5}$

So our foci is

$(2, - 5 + \sqrt{5} )$

and

$(2, - 5 - \sqrt{5} )$

Alborosie

Equations don't have minimum or maximum, functions do.

Function y=2n^2+5n-25 has minimum -28.125, has no maximum.

What is the slope of the line containing (-2, 5) and (4,-4)?

Pachacha [2.7K]

Answer:

Option C is correct.

Step-by-step explanation:

<h2> $slope \: = \: \frac{y2 - y1}{x2 - x1}$ </h2><h3> $= \frac{ - 4 - (5)}{4 - (2)}$ </h3><h3> $= \frac{ - 9}{4 + 2}$ </h3><h3> $= \frac{ - 9}{6}$ </h3><h3> $= \frac{3( - 3)}{3 - 2}$ </h3><h3> $= - \frac{3}{2}$ </h3><h3>Hope it is helpful....</h3>
