Answer:
x=2
Step-by-step explanation:
y = x^2 -4x-8
This is in the form y = ax^2 + bx +c
The axis of symmetry, h is found by h=-b/2a
We know a = 1, b=-4
h = -(-4)/ (2*1)
=4/2
=2
The axis of symmetry is x=2
Answer:
<u>The student's final score is 77.2 and he earned a C letter grade</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the math problem correctly:
Midterm = 5% of the final grade and score of 60
Class project = 10% of the final grade and score of 92
Set of homework = 35% of the final grade and score of 80
Final exam = 50% of the final grade and score of 74
2. What is the student's final score?
Final score = (60 * 0.05) + (92 * 0.1) + (80 * 0.35) + (74 * 0.5)
Final score = 3 + 9.2 + 28 + 37
Final score = 77.2 and letter grade of C
Answer:
See below.
Step-by-step explanation:
An example would be:
3x^2 + 6
and

The second way is found by dividing the first one by 3).
Answer:
Negative
Step-by-step explanation:
The line is trending downwards, which is indicative of a negative slope.
Step-by-step explanation:
there is no diagram so I'm just going to guess this however
sin x = 6/9
sin x = 2/3
sin x = 0.67
x = sin inverse of 0.67
x = 42.1
