Answer:
A. y - 3 = -(x + 5)
Step-by-step explanation:
The general formula for point-slope form is:
, where 'm' is the slope and
is a point on the line
Using the given graph, you can see that the line is downhill, indicating a negative slope. Starting at the y-intercept of -2 and going down two and over two to the point (2, -4) tells us the overall slope is '-1'. You can also see that there is a point at (-5, 3) on the graph. Using the slope (-1) and the point (-5, 3):
y - 3 = -1(x + 5)
Answer – The sum of their measures is 180 degreed
When two diameters of the same circle intersect, four arcs are created. The
following are true of these arcs:
- Opposite arcs are equal in measure
- The sum of the measure of adjacent arcs is 180 degrees
- The sum of the measure of all the arcs is 360 degrees
Answer:
<em>The sound level would be at 80 decibels at 1 or 7 number of measures played</em>
Step-by-step explanation:
<u>Equations with Absolute Values</u>
We have the function s to represent the sound level in decibels:

Where x is the number of measures of the music played.
We are required to find the value of x that makes s=80 decibels. We have to find the equation:

Subtracting 50:


Dividing by 10:


For the absolute value be equal to 3, its argument could be positive or negative:

Or

This leads us to two solutions:

x=7
Or


x=1
The sound level would be at 80 decibels at 1 or 7 number of measures played
