Is y equals 2x plus 5 a direct variation if so what is the constant of variation?
No, it is not a direct variation.
Is y plus 8 equals -x a direct variation?
No.
Is 3x plus y equals 6 a direct variation?
Yes
Can ax plus by equals c be a direct variation if a and b and c does not equal 0?
No, direct variation is "y=ax." In direct variation a equals any real constant, b=1, and c must equal zero. If any of thee conditions are changed, it is not direct variation.
How do you solve the direct variation y equals 5x plus 1?
y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.
Is 0.8x0.5y-2 a direct variation?
Some symbols not visible. Please resubmit using words eg "plus", "equals" etc
Does y plus 2 equals x show direct variation?
No, y+2=x does not show direct variation. In direction variation you need to be able to multiply y by something to get x. In the question y+2=x, you have to add 2 to y to get x, which is not multiplying.)
When will be the linear equations a1x plus b1y plus c1 equals 0 and a2x plus b2y plus c2 equals 0 has unique solution?
When (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
What is -5c plus d equals 2c?
It is a single equation of direct proportionality. It cannot be solved since that would require two linear equations.
What is the correct classification of this system of equations -2x plus y equals 7 3y equals 6x plus 4?
Inconsistent linear equations in two variables.
Which type of lines match these equations 4y plus 8x equals 20 y equals -2x plus 5?
The two equations represent the same straight line.
What is the system of equations set in order pairs 3x plus 4y equals 38 5x - 5y equals -30?
Simultaneous equations.
