The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
Y_Kistochka [10]
Ur independent variable is ur x values....ur dependent variable is ur y values..so if hrs are on the x axis, then ur independent values are ur hrs (or time)....and ur dependent values are ur distance.

(0,0),(2,50)
slope = (50 - 0) / (2 - 0) = 50/2 = 25

y = mx + b
slope(m) = 25
and since u have point (0,0), ur y int (b) = 0
so ur equation is y = 25x + 0 which is written as y = 25x...which is basically saying that he travels 25 miles per hr

how far will he travel in 24 hrs.....so sub in 24 for x
y = 25(24)
y = 600 miles

in summary : The dependent variable is distance, the equation is y = 25x and the dragonfly will fly 600 miles.

Please Hurry! What is the solution to log2_(9x)-log2_3=3?
brilliants [131]

Answer:

log_{2}(9x)  - log_{2}(3) = 3 \\ 3 =  log_{2}(8) or log_{2}( {2}^{3} )  \\  log_{2}( \frac{9x}{3} )  = log_{2}(8) \\  \frac{9x}{3}  = 8 \\ 9x = 8 \times 3 \\ 9x = 24 \\ x =  \frac{24}{9}  \\ x =  \frac{8}{3}  \\ x = 2 \times \frac{2}{3}
