Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
Answer:
Unit rate: $15 per hour
ordered pair: (1 ,15)
Step-by-step explanation:
30 ÷ 2 = 15
45 ÷ 3 = 15
--------------------------------------------------------------------------------------------------------
they both have 15, which means the graph is proportional and the unit rate is $15 per hour
First solve the 2 inequalities for x:-
x > 0 or x <= -5
The last choice is the correct one.
Answer:
£5.04
Step-by-step explanation:
Let's first find the unit cost.
£3.60/2.5kg = £1.44/kg
To find out how much money 3.5kg of apples costs, we simply need to multiply the unit price by 3.5.
£1.44/kg * 3.5kg = £5.04.
