If y equals 3x and 3x equals 12 then what does y equals?
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
How do you solve for y 3x-y equals 12?
-9
3x minus y equals 9 solve for y?
3x-y=9 y=3x-9
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
3x - 7y equals 36 and y equals 3x?
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
5x2 y equals 3x-6y as a function?
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
Rewrite the equation in function form -3x plus y equals 12?
y=3x+12
What is the inverse function of y equals 3x-3?
6
What If y is a function of x in the equation y equals 3x - 5?
-2
Is y equals -3x plus 3 a function?
yes
Is y equals 3x plus 1 and -2x2 a function?
No.
Is y equals 3x-1 a function?
4
Is y equals 3x-2 a function?
5
Which statement best explains why y equals 15 plus 3x is a function?
If you mean: y = 15+3x then it is the function of a straight line equation.
Is y equals 3x squared plus 2x -3 a function?
Yes.
How can you define when the Graph is Function or not?
If a graph is a function, it will always have y=... or x=... (or anoher letter equals an equation) for example y= 3x-12 is a function
Are 3x-y equals 4 and y equals 3x-4 equivalent to each other?
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
