Answer:
Step-by-step explanation:
From the graph B,
Let the equation of the line representing the relation between hours spent in studying 'S' and hours spent in class 'C' is,
S = mC + b
Where m = Slope of the line
b = y-intercept of the line
We choose two points (2, 1), and (4, 2) lying on the line.
Slope 'm' =
m =
m =
y-intercept 'b' = 0
Equation of the line will be
S =
The answer to that question is 7 . You have to add 7 to both sides
Answer:
The answer would be 3.
Step-by-step explanation:
-2x= -6-x+3 First you would add the x to each side. Then you are left with..
-x= -6+3 Now add 3 to -6
-x= -3 Now to get rid of the negative sign on the x, divide each side by -1.
x=3 That would be your final answer.
To Check Your Work, plug in 3 to the two x in the original equation, and see if you will get a true statement.
-2x=-6-x+3
-2(3)= -6-3+3 The threes would cancel out because -3+3=0
-6 = -6 This is a true statement so that means x=3 is the correct answer
Answer:
you are left with 1/2
Step-by-step explanation:
1/3+ 1/6= 3/6 =1/2
Answer:
the are perpendicular to each other (option B)
