What is x in this equation x plus 7x - 2 plus x plus 7x -2 equals 60?
X=4.2666666666667
Solve x3 plus 7x equals 8x2?
x3 + 7x = 8x2x3 + 7x - 8x2 = 0 [subtract 8x2 from both sides]x(x2 + 7 - 8x) = 0 [factor out x]x(x-1)(x-7) = 0 [factor]Since the product of the three factors x, x-1, and x-7 equals zero, any of the three expressions could equal zero:x = 0x - 1 = 0, x = 1x - 7 = 0, x = 7Therefore, there are three solutions to the equation x3 + 7x = 8x2:x = 0x = 1x = 7Or, in set notation: x = {0,1,7}
5x plus y equals 5 3x plus 2y equals 3?
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
Rewrite the equation 7x plus 2y equals 0 in slope-intercept form?
7x = -3y + 12
What is -10 plus 7x plus 4x equals 78?
It is an equation and the value of x is 8
What is A equation for -2x plus 8 equals 7x-10?
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
What is x in this equation x plus 7x - 2 plus x plus 7x -2 equals 60?
X=4.2666666666667
How do solve 7x plus y equals 8 in y equals mx plus b form?
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
Solve x3 plus 7x equals 8x2?
x3 + 7x = 8x2x3 + 7x - 8x2 = 0 [subtract 8x2 from both sides]x(x2 + 7 - 8x) = 0 [factor out x]x(x-1)(x-7) = 0 [factor]Since the product of the three factors x, x-1, and x-7 equals zero, any of the three expressions could equal zero:x = 0x - 1 = 0, x = 1x - 7 = 0, x = 7Therefore, there are three solutions to the equation x3 + 7x = 8x2:x = 0x = 1x = 7Or, in set notation: x = {0,1,7}
5x plus y equals 5 3x plus 2y equals 3?
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
Rewrite the equation 7x plus 2y equals 0 in slope-intercept form?
7x = -3y + 12
What is -10 plus 7x plus 4x equals 78?
It is an equation and the value of x is 8
Why the equation 7x plus 3 equals 7x plus 3?
Why not? The statement is trivially true, meaning it holds for all values of x.
What is the solution of the equation 7x plus 9 equals 51?
7x + 9 = 51 7x = 42 x = 42/7 = 6
What is the equation of the xz-trace for the plane 7x 2y plus 3z equals 19?
Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19
