Recall that the slope-intercept form of the equations of a line is:
Taking both equations to their slope-intercept form we get:
Notice that both equations are the same, therefore the system has infinitely many solutions, therefore it is consistent and dependent.
Answer:
Equations:
The system is consistent and dependent.
A solution to the system is (0,-5).
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
The inequality that represented this situation is
substitute the values and solve for t

Answer:
sign(f(3)) ≠ sign(f(4))
Step-by-step explanation:
The intermediate value theorem tells you that a sign change between f(a) and f(b) means there is a root in the interval [a, b].
Here, we have f(3) ≈ +2.9 and f(4) ≈ -17.6, so there is a root in [3, 4].
_____
The root is approximately 3.27560108885.
