-3x + 6 = 18...subtract 6 from both sides
-3x = 18 - 6
-3x = 12...divide both sides by -3
x = -12/3 reduces to -4 <===
25%
Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%
Answer:
-4
Step-by-step explanation:
Compare this to the form ...
y -y1 = m(x -x1)
which is the point-slope form of the equation for a line. Matching the parts of the equation, you see that ...
m represents the slope of the line. The slope is -4.
<u>Given</u>:
The distance (in kilometers) Dora hiked is modeled as a function of time.
We need to determine the average rate of change in distance hiked, measured in kilometers per hour, between 8:30 am to 1:30 pm.
<u>Average rate of change:</u>
Let us write the time and the distance hiked in coordinates for the time 8:30 am and 1:30 pm.
Thus, the coordinates are (8.30, 4) and (1,12)
The average rate of change can be determined using the formula,

Substituting the points (8.30, 4) and (1.30,12), we get;



Rounding off to the nearest whole number, we get;

Therefore, the average rate of change is -1.
Answer:
The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent
Step-by-step explanation:
The given data can be presented as follows
Year
Number of Photos
2015
236
2016
214
The percentage decrease in the number of candid pictures is give by the following formula

Where;
Original value for the number of pictures = 236
New value for the number of pictures = 214
Substituting the values into the equation for the percentage decrease gives;

The percentage decrease is approximately 9.3 percent.
