Answer:

$x = \frac{46}{3}$

Step-by-step explanation:

A straight angle is equal to 180° degrees. Since both 9x +4 and 3x -18 is supplementary then I can make this claim below

$(9x + 4 ) + (3x - 8) = 180$

All we have to do now is to solve for x

$(9x + 4) + (3x - 8) = 180 \\ 9x + 4+ 3x - 8 = 180 \\ 12x - 4 = 180 \\ 12x = 184 \\ x = \frac{184}{12} \\ x = \frac{46}{3}$

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year

SashulF [63]

Answer:

640 foxes

Step-by-step explanation:

The actual formula is $y = 40 * 4^{x}$

Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.

26 / 13 = 2 periods

Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...

$y = 40 * 4^{x}$

$y = 40 * 4^{2}$

$y = 40 * 16$

$y = 640$

Finally, we can see that there should be 640 foxes after 26 years.
