Step-by-step explanation:
A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².
If l and b are length and breadth of the rectangle.
Area,
Perimeter,
Put the value of l from equation (1) to equation (2). So,
Put the value of b in equation (1),
If b = 5 cm
If b = 9 cm
So, the dimensions of the playing card is 9 cm by 5 cm.
Answer:
changing the currency $ to #
$1000 = #415,640.00
i=prt (formular)
given:
I =?
p = $1000 or #415,640.00
r = 6%
t = 2 years
i= 415,640.00×6×2÷100
i= #49876.8
without changing currency
i= 1000×6×2÷100
i=120

Answer:
Option B is correct
Step-by-step explanation:
A function has form of f(x) = 2x + 3, or y = 2x + 3
To find the inverse of f(x), we are going to represent x in form of y.
To do this, we try to send all components containing x to one side of expression and send the other components to the other side of expression.
Now, let's do it.
y = 2x + 3
We firstly send 3 to the right, change the sign of 3 from + to -, we have:
y - 3 = 2x
We then rearrange both sides to get a standard form:
2x = y - 3
We now divide both sides by 2 to get the expression of x:
(2/2)x = (y - 3)/2
We simplify both sides of expression to obtain final result:
x = (1/2)y - 3/2
=> Inverse of f(x) is x = (1/2)y - 3/2
=> Option B is correct
