Answer:
2.
Step-by-step explanation:
The gradient or slope of a straight line which is found between two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Where y2 = 7
y1 = 3
x2 = 4
x1 = 2
=> m = (7 - 3) / (4 - 2)
m = 4 / 2 = 2
The gradient is 2.

y = (x-3)² has horizontal translation RIGHT 3 unit from y = x²
Answer:
Speed of boat in still water is 6km/h
Speed of current is 4km/h
Step-by-step explanation:
We know speed = distance / time
Let the speed of boat in still water be x
Let the speed of current be y
Hence the speed of boat, down stream =
Distance downstream = 20km
Time taken = 2 hours
We have
......(1)
Speed of boat upstream =
Distance upstream = 4
Time taken = 2
We have
...(2)
Adding (1) & (2)
Substituting in (1) we get
Answer:
A) $3.55
Step-by-step explanation:
What we know:
If <em>c</em> ( acustomer) orders 4 pizzas, each pizzas cost $4.44
There, we can multiply $4.44 by 4 to get $17.76.
Mr. Pelee wants to give the driver a 20% tip.
So, divide 17.76 by 5 (or multiply by 1/5) to get 3.552.
But, it's asking us to round to the nearest cent.
2 is less than 5, so 3.552 rounds down to $3.55
