Since x & y vary inversely (it means when x increases, y decreases & vice versa)
Then the equation==> y = k/x (k is a constant to be calculated)
But x=9 and y=3 (given) ==> 3=k/9 or k=27 & the equation becomes y=27/x
Hi there! In order to find the simple interest rate of the bonds, we have to divide the received payment by the bonds invested in them. 504/8,000 is 0.063. This number is in decimal form, but let's multiply by 100 to get the percentage of the number. 0.063 * 100 is 6.3. There. The simple interest rate of the bonds is 6.3%.
Option C (in the figure) is correct.
Step-by-step explanation:
We need to find (f.g)(x)
Given that

Answer:
this equation cannot be written in slope-intercept form
Step-by-step explanation:
The given equation is equivalent to ...
2x +9 = 0 . . . . . subtract 1x
x + 4.5 = 0 . . . . divide by 2
x = -4.5 . . . . . . . the equation of a vertical line.
It has no y-intercept and its slope is undefined.
