y ≤ x − 5

y ≥ −x − 4

This is a check and see type of problem.

if x=5

y ≤ 5 − 5 y≤ 0

y ≥ −5 − 4 y ≥-9

-9≤ y ≤ 0

-2 works so (5,-2) is a solution

if x= -5

y ≤ -5 − 5 y≤ -10

y ≥ 5 − 4 y ≥1

no solution

Choice B (5,-2)

Sophia's credit has an APR of 20.87 % and it just changed its compounding. From monthly to daily what will happen to the effecti

Rashid [163]

Answer:

It will increase by 0.2%.

Step-by-step explanation:

In this problem we need to solve for the monthly interest first.

We use the formula:

$r = (1+\dfrac{i}{n})^{n}-1$

Now that we have the formula we now define our variables.

i = 20.87% or 0.2087

n = 12

$r=(1+\dfrac{0.2087}{12})^{12} - 1$

$r=(1+\dfrac{0.2087}{12})^{12}-1$

$r=(1+\dfrac{0.0174})^{12}-1$

$r=(1.0174})^{12}-1$

$r= 1.2299-1$

$r= 0.2299$ or 23%

Now we have to find the daily interest rate.

$r=(1+\dfrac{0.2087}{365})^{365}-1$

$r=(1+0.00057178082)^{365}-1$

$r=(1.00057178082)^{365}-1$

$r= 1.2320-1$

$r= 0.2320$ or 23.20%

23.20% - 23% = 0.20% increase.

Suppose it takes you 14 hour to drive to the movie theater at a rate of 40 mph. Your friend lives closer to the movie theater th

dezoksy [38]

Answer: (d)

Step-by-step explanation:

Given

It takes 14 hours with 40 mph to reach the theatre

so, the distance traveled is given by

$\Rightarrow d_1=40\times 14\\\Rightarrow d_1=560\ \text{miles}$

It is given that d is the distance from theatre to friend's house

So, d must be less than $d_1$ i.e.

$d$

So, the most appropriate option out of the given is option (d) as d must be less than 560 and it is possible that it maybe less than 160.
