Answer:
Y=-2
Step-by-step explanation:
You would use the vertex form to find the directrix
27 * 35
= 20*35 + 7 * 35
= 700 + 245
= 945
Answer:
x = 10
Step-by-step explanation: 10/2 = 5 + 1 = 6
Answer:
For the first city, the 95% confidence interval would be:
28,900 +/- 2300 x 3 = 28,900 +/-6900$
For the second city, the 95% confidence interval would be:
30,300 +/- 2100 x 3 = 30,300 +/- 6300$
Answer:
x = -1/2
Step-by-step explanation:
To solve the equation, we first need to combine like terms:

Simplify further:

Divide by -12 on both sides to get:

To check the solution, plug x back into the original equation and check if we get the correct answer:



Thus, it checks out and our answer is correct.
