13 and 15<br><br>solve each problem by graphing and slope intercept​
mylen [45]

Answer: The answers are 13. (A) and 14. (B).

Step-by-step explanation: The calculations are as follows:

(13) The given equations are

y=-\dfrac{3}{8}x-6,\\\\\\y=-\dfrac{13}{8}x+4.

In the attached figure (a), these two lines are drawn. We can see that The lines intersect at the point P(8, -9). So, the solution to the pair of equations is (8, -9).

Thus, the correct option is (A).

(14) The given equations are

y=-\dfrac{1}{7}x-1,\\\\\\y=-x+5.

In the attached figure (b), these two lines are drawn. We can see that The lines intersect at the point Q(7, -2). So, the solution to the pair of equations is (7, -2).

Thus, the correct option is (B).

A population of amoebas in a petri dish will triple in size every 20 minutes. at the start of experiment the population is 800.
sp2606 [1]
If we are to derive the equation that models the growth of the amoeba, we make use of the general form:
p = po k^t
where po is the initial population
k is the multiplicative rate of change

From the problem
3po = po k^(20)
k = 1.06

The equation is
p = 800 (1.06)^t
