Speed against current = 120 miles / 6 hours = 20 miles / hour
Speed with current = 120 miles /5 hours = 24 miles / hour.
Speed of boat in still water = (20+24)/2 = 22 miles / hour
B. three units down and one unit right
x minus will always translate down, x plus will always translate up.
y minus will always translate left, y plus will always translate right.
Answer:
The value of y for x = 8 is 60 .
Step-by-step explanation:
Given expression as :
For x = 2 , y = 15
Let the equation be written with constant k'
So, y = k x
Or, k =
∴ k =
<u>Now, again </u>
For x = 8
equation can be written as
y = k x
Or, y = × 8
Or, y =
∴ y = 15 × 4
I.e y = 60
Hence The value of y for x = 8 is 60 . Answer
Answer:
Step-by-step explanation:
Factor the denominator and cancel the common factor.
