The functions are:

and

.
After 2 weeks, under no risk of spiders, the population of the flies is calculated by the function as

.
Similarly, we calculate s(2)=2(2)+5=4+5=9, which means that the spider consumes 9 flies in 2 weeks.
Thus, out of 32 flies, 9 are eaten by the spider, so there are 32-9=23 flies left.
Answer: 23
Just make lines. for example 6 divided by 2. draw 6 boxes and split then in to 2 and its 3. otherwise just divide 6 divided my 2 is 3.
Answer:
yes, it passes through the origin and has a 1 slope.
the car traveled 100 miles in 2 hours.
the car traveled 250 miles in 5 hours.
the car traveled 50 miles in 1 hour.
Step-by-step explanation:
Quadratic equation is

WHEN

So, to make this true subtract 7 from each side.
The equation is now
7

- x - 7 = 0
Values for a, b, and c: a = 7, b = -1, c = -7
Plug these variables into the quadratic equation.
Square -1 to get 1 and multiply -4 x 7 x -7 to get 196.

Multiply 2 x -7 to get -14, the denominator, and add 1 to 196.
Since 197 is not a square number, and I don't know if you want to leave it in radical form or not, I will just because it's easier to understand.
Hope this helps!
