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.
Y equals 3x-4 and y equals 4 plus x solve by elimination?
y = 3x - 4 y = 4 + x Subtract the second equation from the first: y - y = 3x - 4 - 4 - x 0 = 2x - 8 2x = 8 so that x = 4 Substitute for x into second equation: y = 4 + 4 = 8 So the solutions is (4, 8).
How do you graph -3x-y equals 4?
Get in function form. - 3X - Y = 4 - 1(- Y = 3X + 4) Y = - 3X - 4 ----------------------------solve for X and Y by the 0 out method - 3X - 4 = 0 - 3X = 4 X = - 4/3 --------------- Y = - 3(0) - 4 Y = - 4 -------------- Draw a line linking those points.
What is the orded pair for 3x plus y equals -1 5x-y equals 9?
3x+y=-1 y=-1-3x5x-y=9 5x-(-1-3x)=95x+1+3x=98x=8x=1y=-1-3(1)y=-4(1,-4)
If T equals 3x plus 7y what is T when x equals 4 and y equals 6?
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
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.
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!
Y equals 3x-4 and y equals 4 plus x solve by elimination?
y = 3x - 4 y = 4 + x Subtract the second equation from the first: y - y = 3x - 4 - 4 - x 0 = 2x - 8 2x = 8 so that x = 4 Substitute for x into second equation: y = 4 + 4 = 8 So the solutions is (4, 8).
What is the gradient of y equals 3x plus 4?
y=3x+4 -3x+y=4 x=-1/3
What is 3x y equals 4 and x y equals 0?
A pair of simultaneous eq;ns. 3x + y = 4 x + y = 0 Subtract the two eq'ns. This will eliminate 'y' 2x = 4 x = 2 Substitute this value of 'x' into either eq'n for 'y' 2 + y = 0 y = -2 or 3)2) + y = 4 6 + y = 4 y = 4 - 6 y = -2 ( again) . So the answer is ( x,y) = ( 2, -2).
Are y equals -3x plus 2 and y plus 3x equals 4 parallel?
Their graphs are.
Convert y equals 3x-4 into standard forn?

If y equals 3x and 3x equals 12 what does y equal?
y = 12. It's the transitive property. y = 12 = 3x.
Where do the lines 3x-y equals -4 and 3x-y equals 0 intersect?
3x - y = -4 3x - y = 0 Those lines do not intersect. They are parallel. You can demonstrate by solving either of them for one of the two variables, then plugging it's value into the other: 3x - y = -4 ∴y = 3x + 4 Now substitute: 3x - y = 0 ∴ 3x - (3x + 4) = 0 ∴ 3x - 3x - 4 = 0 ∴ -4 = 0 This result is obviously incorrect, indicating that the lines do not intersect.
What is the equation of a line perpendicular to y equals -3x plus 4?
y = 1/3x+4
What would be three equations parallel to y equals 3x plus 4?
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
What is the y intercept of y equals 3x plus 4?
