Is the point (1,-3) a solution to the system? show all your work y>x-1 y >-x+2

vagabundo [1.1K]

Answer:

To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

- x + 2 = - 1 + 2 = 1

Now - 3 < 1

Thus (1, - 3) is not a solution

You have agreed to loan some money to a friend at a simple interest rate of 180% which is outrageous but still about half of the

choli [55]

Answer:

the amount borrowed is ≅ $527

Step-by-step explanation:

Given that;

simple interest rate r = 180% p.a

Let the amount borrowed (principal) be $x.

time t = 4 weeks = 28 days

= 28/365 year

= 0.0767 year

we all know that :

$Simple \ \ interest = \dfrac{P*r*t}{100}$

$Simple \ \ interest = \dfrac{x*180*0.0767}{100}$

Simple interest = 0.13806x

Total amount to be paid after 4 weeks= Interest+Principal

= x + 0.13806x

= 1.13806x

Thus;

1.13806x = $600

x = $600/ 1.13806

x = $527.21

Hence; the amount borrowed is ≅ $527
