Answer: 28 decibels.
Step-by-step explanation:
1. To solve this exercise you must observe the graph attached in the problem, where the intensity of the sound is represented in the x-axis and the decibel measure is represented in the y-axis.
2. As you can see in the graph, when the value of x is 500 (x=500) the value of y is 28 (y=28).
3. Therefore, the answer is the second option: 28 decibels.
Answer:
y = -2/3x - 3
Step-by-step explanation:
y = mx + b
m = slope
(-3,-1) = (x,y)
<em>Plus in the coordinates</em>
-1 = -2/3(-3) + b
<em>negative times negative = positive</em>
-2/3 * -3 = 2
-1 = 2 +b
<em>Use inverse operations</em>
-2 --2
-3 = b
y = -2/3x - 3
Answer:
Answer 1.25
Step-by-step explanation:
Tolal moths he take to read 8 book = 10
Therefore, Total month he will take to read 1 book =10/8=1.25
Answer:
x - 3 = y
Step-by-step explanation:
The answer is the third equation.
This is because the y-intercept is -3 and the x-intercept is at (2,0) (you can find the x-intercept by making "y" = 0). The only equation that has both of these is the third one.
