Answer:
1. Equilibrium solution: y= -3
2. Equilibrium solution y= ±1.414
Step-by-step explanation:
Thinking process:
The equilibrium solution can only be derived when 
1. Let's look at the first equation:

equating
to the expression
gives
y + 3 = 0
y = -3
Therefore, the equilibrium solution occurs at y = -3
2. Let's look at the second solution:

dividing each side by (t²-1) gives
1/(t²-1)
= (y²-2)/ (y²-4)
factorizing the right hand side gives:
at equilibrium:
, then
y² - 2 = 0
solving for y gives y = ±√2
= ±1.414
Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Check all that apply.
(x + 1)
(2x + 1)
(x + 2)
(5x + 1)
<span>(5x – 2)
Solution :
By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow.
</span>(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
= <span>5x^2 + 10x - 2x - 4
= </span>5x^2 + 8x - 4
The answer to the question is letter C. 4(x + 3). The expression means that the sum of x and 3 is multiplied by 4. This expression should be equal or greater than 28. All the other choices do not satisfy the inequality.

(7+15) + (1/4 +7/8)
22 + 2/8 + 7/8
22+ 9/8
