I. After how many weeks will Jennifer and William have the same amount of money in their bank accounts? ii. How much will be in their accounts?

Step-by-step explanation:

Jennifer's account:

William's account can be expressed as:

Because the rate of change is 14 and y-intercept is 30

They will be same after x years, f(x) = g(x)

The accounts will be same after 5 weeks

The amount in the accounts after 5 weeks:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
