I think it is about rates; Ian can pay his parents back in roughly 16 months. Ken can pay his parents back in 30 months.
Ian: 1000$ / 60$m = 16.6 m
Ken: 600$ / 20$m = 30m
Easy,
write the coordinates out in pairs:
x= hours
y= earnings
(1,10)
(2,20)
(3,30)
(4,40)
(5,50)
Now it makes it much easier to see the increase,
After 1 hour of working she has made $10
After 2 hours of working she has made $20
<span>After 3 hours of working she has made $30
</span>
And so on,
that being said it's easily seen that she is getting paid $10
Thus the unit rate is $10.
Translations. You are moving it around.
The value of the product expression given as product of (2i) and (5+3i) is 10i -6
<h3>How to determine the product?</h3>
The product expression is given as:
product of (2i) and (5+3i)
Rewrite the expression as:
(2i) * (5+3i)
Open the brackets
(2i) * (5+3i) = 10i + 6i^2
Evaluate
(2i) * (5+3i) = 10i + 6(-1)
This gives
(2i) * (5+3i) = 10i -6
Hence, the value of the product expression given as product of (2i) and (5+3i) is 10i -6
