Answer: c ax + b = ax+ b
Step-by-step explanation: Seems like a trick question, especially since Answer c has no c in the equation. But once you put in numbers for a,b,and c, there cannot be infinite solutions for x in the first two examples.
Set up two or three equations and test them as proof.
Answer:
a. 7.64 km/h
b. 6.0°
c. see below
Step-by-step explanation:
a) The total velocity of the boat is ...
7i +(0.6i +0.8j) = 7.6i +0.8j
The magnitude of this velocity is the speed of the boat, relative to land. That is given by the Pythagorean theorem.
|7.6i +0.8j| = √(7.6² +0.8²) = √58.4 ≈ 7.642 . . . . km/h
__
b) The angle of the total velocity with respect to the "i" direction (the direction of vector v) is ...
α = arctan(0.8/7.6) ≈ 6.009°
__
c) The boat is headed in a direction 6° different from its velocity relative to the water. That may need to be accounted for if the boat is traveling any significant distance.
The answer is 22
All you had to do was add 9+13 and that’s give you 22
Oof idk if u like bts but I saw ur username said jiminahh
Answer:
x = 12
Step-by-step explanation:
Since the top line is equal to the bottom, you make the equation -
x + x + 4 = x + 16
You subtract an x on both sides because there is one on each side -
x + 4 = 16
Then you subtract the 4 from both sides to get x by its self, which makes
x = 12
