Identify the graph of the equation. what is the angle of rotation for the equation? 2xy – 9 = 0

a. hyperbola; 90° c. ellipse; 30° b. hyperbola; 45° d. ellipse; 60° select the best answer from the choices provided a b c d

B. Hyperbola; 45 degrees

Step-by-step explanation:

refer to the image, it is what the equation looks like graphically.

it's a hyperbola with the x- and y-axis as asymptotes.

90 degrees means that it would shift into the II and IV quadrants, so 45 degrees means that it would stay in the I and III quadrants.

also by simplifying the equation you get xy=9/2 which also equals 4.5-

triangle and cube

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
