Therefore it has 2 rational soltions
The given equation solved for A is A = (T + 5)/ B
<h3>Solving linear equation</h3>
From the question, we are to solve the given equation for A
To solve the equation for A, we will simply make A the subject of the equation
The given equation is
T = AB - 5
Solving for A
T = AB - 5
Add 5 to both sides of the equation
T + 5 = AB - 5 + 5
T + 5 = AB
Divide both sides of the equation by B
That is,
(T + 5)/B = AB/B
(T + 5)/B = A
∴ A = (T + 5)/ B
Hence, the given equation solved for A is A = (T + 5)/ B

The answer to the question is 96
Answer:
2s or 3s
Step-by-step explanation:
Given the function that models the height of the object as;
h(t) = - 16t^2 + 80t + 96
The ball reaches the ground when h = 0
Substitute
0 = - 16t^2 + 80t + 96
Divide through by -16
0 = t²-5t-6
t²-5t-6 = 0
t²-2t-3t+6 = 0
t(t-2)-3(t-2) = 0
(tt-2)(t-3) = 0
t - 2 = 0 and t-3 = 0
t = 2 and 3s
Hence it will take the ball 2s or 3s to reach the ground
Answer:
Step-by-step explanation:
Initial value ( y - value) for Function A is 12.
For B its 3(-1) + 2 = -1 so the answer is Function A.
