Answer: -11 & 9
Step-by-step explanation: Coefficients are the numbers before the variables.
Answer:
Suzanne is incorrect.
Step-by-step explanation:
To figure out if the two equations are equivalent, we can simplify each one of them.
Simplifying the first equation, we get:
Simplifying the second equation, we get:
Now that both equations are simplified, we can see that the equations are not equivalent. Suzanne is incorrect.
The slope of a line that passes through the point (-3,0) and has a y-intercept of 12 is 4.
<h3>How to find the slope of a line?</h3>
Using the point slope equation,
y = mx + b
where
Therefore, using (-3, 0)
0 = -3m + 12
-12 = -3m
divide both sides by -3
m = -12 / -3
m = 4

Step-by-step explanation:
the graph crosses the y-axis at (0,5) , increasing from x=-10 to x=2 and decreasing from x=2 to x=10
Answer:
92 dB
Step-by-step explanation:
Use the mean formula, mean = sum of elements / number of elements.
Since it is a 8 hour work day, there are 8 elements.
mean = sum of elements / number of elements
mean = (98 + 98 + 98 + 98 + 98 + 82 + 82 + 82) / 8
mean = 736 / 8
mean = 92
So, the average noise level is 92 dB
