An antique clock cost £540. its price is increased by 18% in a year. what is it now worth?
1 answer:
Well, we don't know how many years we're talking about?
Let's say we want to know the prize after one year: it's 540 +540 * 18%.
another way of writing it is 540* 118%. (this is 637.2)
after two years it will be:
540*118%*118%
we can also write it without =%: (as 100 % is always 1, 101% is 1.01 etc)
540*1.118*1.118
we can also make a more general statement:
n=number of years that have passed:
prize of the clock now=540*

Answer:
The coordinates of the points that are members of the solution set
(-3,7), (0,4) and (2,3)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area above the dashed line
----> inequality B
The solution of the inequality B is the shaded area above the solid line
The solution of the system of inequalities is the shaded area between the dashed line and the solid line
see the attached figure
Remember that,
If a ordered pair is a solution of the system of inequalities, then the ordered pair must be in the shaded area of the solution
Plot the points
(-3, 7), (-3, -7), (3,-7), (-4,-0), (0,-4), (0,4), (2,3), (-2,3), (2,-3)
therefore
The coordinates of the points that are members of the solution set
(-3,7), (0,4) and (2,3)
