Answer:

The answer is "Option A"

Step-by-step explanation:

The domain is the collection of the value, which belongs to the separate variable (horizontal axis). So, to find a region with a graph, it must search for the function, which starts and end. And at all these levels we are searching at x-values.

Its starting point is (2,9) and the ending point is (8,3). Therefore, x= 2 to x=8 is the domain.

Answer:

Mizuki here to help!

8 minutes longer will be the correct answer!

Step-by-step explanation:

First, let's find out how many minutes Gabriella played:

3:32 - 2:49 = 2:92 - 2:49 = 0:43

Check:

2:49 + 0:43 = 2:92 = 3:32

It's correct so...

43 - 35 = 8

Hope this helped!

Mrrafil [7]

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:

x=5

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−12=−4x+23

Step 1: Add 4x to both sides.

3x−12+4x=−4x+23+4x

7x−12=23

Step 2: Add 12 to both sides.

7x−12+12=23+12

7x=35

Step 3: Divide both sides by 7.

x=5

Answer:

x=5

Q9: Determine e, k, and identify the type of conic for r= 12/7-cos theta .

lapo4ka [179]

Answer:

eccentricity; e = 1/7

k = 12

Conic section; Ellipse

Step-by-step explanation:

The first step would be to write the polar equation of the conic section in standard form by multiplying the numerator and denominator by 1/7;

$r=\frac{\frac{12}{7} }{1-\frac{1}{7}cos theta}$

The polar equation of the conic section is now in standard form;

The eccentricity is given by the coefficient of cos theta in which case this would be the value 1/7. Therefore, the eccentricity of this conic section is 1/7.

The eccentricity is clearly between 0 and 1, implying that the conic section is an Ellipse.

The value in the numerator gives the value of k; k = 12
