Answer: е) Step-by-step explanation: we know the coordinates of the points so we can easily determine which function this is To begin with, let's take any two points with an integer coordinates let these be two points with coordinates (1 ; 4) and (0 ; 3) Now let's check
and all other options except option e are incorrect because
Answer:
A
Step-by-step explanation:
since milimetres is a smaller unit than centimetre, we will divide. We use division to convert from smaller to bigger value
Answer:
$471.65
Step-by-step explanation:
-The value of the laptop after each year is calculated by the formula:

where:
is the value at time t
is the initial value
is the rate of depreciation
is the time
#We substitute the values to solve for the value after 3 years(2010-2007=3):

Hence, the value of the laptop in 2010 is $471.65
2x + y = 3
x = 2y - 1
solve for y in the first equation;
2x + y = 3
y = 3 - 2x
x = 2y - 1
x = 2(3 - 2x) - 1
x = -4x + 5
solve for x;
x = -4x + 5
x + 4x = 5
5x = 5
x = 1
solve for y;
y = 3 - 2x
y = 3 - 2(1)
y = 1
the answer is: x = 1, y = 1
hope this helps, God bless!
