Step-by-step explanation:
Let's pick two points on the line: 
and 
Let's calculate the slope of this line using these points:
With this value of the slope, we can write the general slope-intercept form of the equation as
To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:
Therefore, the slope-intercept form of the equation is
Answer:
I got x = 1
Step-by-step explanation:
First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:
And since -2.5 is less than -1 this statement is true. x does in fact equal 1
Step-by-step explanation:
Most accurate one would be how many pounds he bought. Occasionally, the number he bought could also be used
Answer:
33 students
Step-by-step explanation:
Fifteen percent of the students in seventh grade at western middle school have perfect attendance. There are 220 students in seventh grade. How many have perfect attendance?
Fifteen percent in decimal from is 0.15.
You would then multiply that by the number of students; 220.
.15 * 220 =
One multiplied, you get 33.
Therefore, 33 students have perfect attendance.
Answer:
49680
Step-by-step explanation:
Multiply 54,000 by 92%. 100%(this years population)-8%=92%
54000*0.92 = 49680, people one year ago.
