-3x+5y=30
+3x+5y=30
5y=3x+30
divide 5 by everything
answer: y=3/5x+6
Notice that for this question, they are providing you with:
1) The slope of the line (4)
2) a point on the plane through which the line goes (6, -2)
So you can directly use for this the "point-slope" form of a line which is as follows:
This includes m as the slope, and the pair (x0, y0) as the pair representing the point the line goes through.
So, let's use the info they gave you to complete this:
which we can work out a little more:
And even a little more to finish the equation of the line in its standard slope-intercept form:
So the equation of the line is:
Answer:
Piece one would equal to 14" and piece two would be 42" because 42 is three times the length of 14
Let,
Lee’s class size = L
Fred’s class size = F
We are told that Lee’s fifth-grade class has 1.0 times as
many students as Fred’s
Therefore, L = 1F
L = F
Question A. If there are a total of 60 students, how many
students does Fred’s class have?
Total number of students = 60
L + F = 60
Since L = F
L + F = F + F + 60
F + F = 60
2F = 60
F = 60/2
F = 30
Therefore, if there are a total of 60 students, Fred’s class
has 30 students.
QUESTION B. If there are a total of 60 students, how many
students does Lee’s class have?
Total number of students = 60
L + F = 60
Since L = F
L + F = L + L + 60
L + L = 60
2L = 60
L = 60/2
L = 30
Therefore, if there are a total of 60 students, Lee’s class
has 30 students.
Answer:
He is incorrect
Step-by-step explanation:
In 1.967, the hundredth is greater than 5. That means you'd round up! So, the correct answer would be 2.
