COMPLETING THE SQUARE (PROCESS):
Do a reverse factoring procedure to develop the following form of equation:
(t + a)^2 = b
where:
t = unknown variable
a = coefficient
b = coefficient
Then take square root of both sides to find value of unknown variable as follows:
t^2 + 10t = 75
(t^2 + 10t + 25) = 75 + 25
(t^2 + 5t + 5t + 25) = 100
(t + 5)(t + 5) = 100
(t + 5)^2 = 100
√(t + 5)^2 = √100
Two solutions exist:
+(t + 5) = 10
AND
-(t + 5) = 10
Thus:
t = 10 - 5 = 5
AND
t = -5 - 10 = -15
Answer:
t = 5
AND
t = -15

Answer: OPTION D .
Step-by-step explanation:
1. By definition the function cut or intersects the y-axis when the value of x is equal 0 (x=0).
2. Therefore, you can observe the table given in the problem and see the value of y when x is equal to zero.
3. Keeping this on mind you can see that when x=0, y=8.
Therefore, you can conclude that the y-intercept in the table is 8.
4. As you can see in the graph, the y-intercept is at 5.
5. Then, since 5<8, the answer is the option D
A linear function can only have one solution, so no matter what type of graph it has it'd only have one solution.
So the answer is B.
