Which conic section does the equation below describe?
Rus_ich [418]

Answer: Option C. Ellipse

Step-by-step explanation:

The general equation of an ellipse has the following form:

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1

Where the point (h, k) is the center of the ellipse

In this case we have the equation

\frac{(x-9)^2}{4} + \frac{(y+2)^2}{25} =1

Note that its shape matches that of a ellipse with center (9, -2)

a=\sqrt{4} \\a=2\\\\\\b=\sqrt{25}\\b=5

Therefore the answer is the obtion C

Point R(5,-3) and point N(9,-4) are on line k. What is the slope of the line passing through these points?
Aleks04 [339]
The slope of a line, denoted "m" is:

m=(y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are any two points on the line.

m=(-4--3)/(9-5)

m=-1/4

So the slope is negative one quarter.

Is this answer right?
lubasha [3.4K]

Solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .

3(8 - 2) + 4 = 22

Parentheses...

(15 - 6)² ÷ 3 - 3³

15 - 6 = 9

(9)² ÷ 3 - 3³

Exponent....

9² ÷ 3 - 3³

In this case you have two exponents. Always apply the steps from left to right

9² ÷ 3 - 3³

9² = 81

81 ÷ 3 - 3³

3³ = 27

81 ÷ 3 - 27

Division...

81 ÷ 3 - 27

81 ÷ 3 = 27

27 - 27

Subtraction...

27 - 27 = 0

0

<u>Your mistake: </u>

You subtracted 3 - 27 before dividing 81 by 3. Remember that according to the rules of PEMDAS division must come before subtraction

Hope this helped!
