Answer:
Then, a=-1 and b=-1
Step-by-step explanation:
We need to solve the following system of equations using the adition method:
2a+3b=-1 (i)
3a+5b=-2 (ii)
First, we multiply the equation (i) by -3 and the equation (ii) by 2, so we get:
-6a-9b=3
6a+10b=-4
Adding the two equations we have:
-6a-9b=3
6a+10b=-4
--------------------------
0 + b = -1
Then b=-1. Now, let's substitute the value of b into equation (i):
2a+3b=-1
2a + 3(-1) = -1
2a -3 = -1
2a = 2
a = 1
Then, a=-1 and b=-1
1. The force necessary to gain a velocity of 60 m/s within 5 mins is 40 N
2. The velocity gained by the object at the end of the second minute is 30 m/s
<h3>1. How to determine the force</h3>
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 60 m/s
- Mass (m) = 200 Kg
- Time (t) = 5 ms = 5 mins = 5 × 60 = 300 s
- Force (F) =?
F = m(v –u) / t
F = 200(60 – 0) / 300
F = 40 N
<h3>2. How to determine the velocity </h3>
- Force (F) = 150 N
- Mass (m) = 600 Kg
- Initial velocity (u) = 0 m/s
- Time (t) = 5 ms = 2 mins = 2 × 60 = 120 s
- Final velocity (v) = ?
F = m(v –u) / t
Cross multiply
m(v –u) = Ft
Divide both sides by m
v - u = Ft / m
v - 0 = (150 × 120) / 600
v = 30 m/s

If this is all there is to the equation it would not have an asymptote.
F(x) =3x+4 is a linear equation and it's domain(possible x values) would be all real numbers. Therefore you would not have a vertical asymptote. This also results in having a range (possible y values) of all real numbers. Again, there would be no horizontal asymptote.
