Answer:
Step-by-step explanation:
There is not possible solution in the real number system or the complex field.
Oddly, before I answer your question, I would point out that the equation given is a perfectly legitimate equation in some computer languages. It has the meaning of
- Take the current value in memory location x
- Subtract 5 from it.
- Put the new result in memory location x.
But that is not what you are being asked about.
The blank you could put in 4
so 4 = 4 - 5
4 = - 1
The second blank will give you the result of 4 = - 1 which can't be true in a million years.
The equation is $58-$32=$26
Answer:
25
Step-by-step explanation:
850-250=500 500 divided by 30 = 25 light sets
Answer:
30 m/s
Step-by-step explanation:
Let's say the distance from the first car to the intersection is x, and the distance from the second car to the intersection is y.
The distance between the cars can be found with Pythagorean theorem:
d² = x² + y²
Taking derivative with respect to time:
2d dd/dt = 2x dx/dt + 2y dy/dt
d dd/dt = x dx/dt + y dy/dt
We know that x = 200, dx/dt = -25, y = 150, and dy/dt = -50/3.
To find dd/dt, we still need to find d.
d² = x² + y²
d² = (200)² + (150)²
d = 250
Plugging everything in:
250 dd/dt = (200) (-25) + (150) (-50/3)
dd/dt = -30
The cars are approaching each other at a rate of 30 m/s at that instant.
