Answer:
2x5 = 10
1xr = 2r
Ans : 10+2r
Step-by-step explanation:
After trying to do it the hard way, i remembered the easy way.
substitution:
because x = 6 and 6 is in the range of -6 < x < 9, we only need the equation 6x^(2) + 2
f(x) = 6x^(2) + 2
f(6) = 6(6)^(2) + 2
f(6) = 6(36) + 2
f(6) = 216 + 2
f(6) = 218
Answer:
Step-by-step explanation:
10 on the y axis and 5 on the x axis
Answer:
10
Step-by-step explanation:
Recall your d = rt, distance = rate * time.
b = speed rate of the boat.
c = speed rate of the current.
keeping in mind that, as the boat goes Upstream, against the current, it's speed is not "b", but is really " b - c ", because the current is subtracting speed from it.
likewise, when the boat is going Downstream, because is going with the current, is really going faster at " b + c ".

what is the speed of the boat? well, 61 + c = b.
