Speed of canoe in still water we will denote it CS and water itself has a speed we denote it WS. Downstream will be (CS + WS)*45 = 2, Upstream will be (CS - WS)*90 = 2. Solve the system you will find canoe speed in still water and the water speed as well. 90CS = 90WS +2, CS = WS+ 1/45 put it in the first function 90WS +1 = 2, WS = 1/90 miles per minute, CS =1/30 miles per minute.
Answer:
x = 12
Step-by-step explanation:
5x - 30 = 2x + 6
3x = 36
x = 12
Answer:
Yes
Step-by-step explanation:
The form of a direct variation equation is
y = kx ← k is the constant of variation
Given
3y = 18x ( divide both sides by 3 )
y = 6x ← equation of direct variation
with k = 6
Answer:
A
Step-by-step explanation:
The graph of ...
f(x) = |x -h| +k
has its vertex at (h, k). If h and k are both positive, the graph will match the description of graph A. (The vertex is in the first quadrant.)
