When x is -5 what is the value of 2x cubed - 3x?
If the equation is (2x)^3-3x, then the answer is -985. However, if the equation if 2(x)^3-3x, then the answer is -235.
What line Is perpendicular to 3x-y5 and whose y-intercept is -7?
If you mean: 3x-y=5 then y=3x-5 and the perpendicular equation is y=-1/3x-7
What is the y-intercept for the graph of the equation 3x - 2y equals 5?
Put in function form. 3X - 2Y = 5 - 2Y = - 3X + 5 Y = 3/2X - 5/2 Y intercept = - 5/2
What is the x 3x plus 5 equals 20?
3x + 5 = -20. First, subtract 5 from both sides of the equation: 3x + 5 - 5 = -20 - 5; and simplify: 3x = -25. Then divide both sides by 3: 3x / 3 = -25 / 3; and simplify: x = -8 1/3 (or -8.33)
What is 3x plus 2y equals 8?
3x + 2y = 8 This is an equation. It could be the equation of a line.
Why the equation 3x 8 3x - 5 has no solutions?
The equation (3x + 8 = 3x - 5) has no solutions because when you simplify it, you subtract (3x) from both sides, resulting in (8 = -5). This statement is false, as 8 does not equal -5. Since the equation leads to a contradiction, it indicates that there are no values of (x) that can satisfy it. Thus, the equation has no solutions.
What is an equation with the answer as 5?
-3x-5+5=20+5 -3x=-15 x=-5
What is the solution to the equation 3x + 5?
3x+5 Solution- 3x+5=0 3x= (-5) x= (-5)/3
Is 3x plus 5 an equation?
No, an equation needs an "=".
How do you solve the equation -3x minus 5 equals -20?
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
How do you Rewrite this equation 3x plus 5y equals 7?
3X + 5Y = 75Y = - 3X + 7Y = (-3/5)X + 7/5==================equation of the line
Which best explains why the equation 3x plus 8 3x - 5 has no solutions?
The equation (3x + 8 = 3x - 5) has no solutions because when we attempt to isolate (x), we end up with a contradiction. Subtracting (3x) from both sides results in (8 = -5), which is not true. Since there are no values of (x) that can satisfy this equation, it has no solutions.
When x is -5 what is the value of 2x cubed - 3x?
If the equation is (2x)^3-3x, then the answer is -985. However, if the equation if 2(x)^3-3x, then the answer is -235.
What is the inequality for y-3x-5?
There is no single inequality for this equation. Inequalities could include y-3x-5 > 0 y-3x-5 < 0 y-3x-5 != 0
What is 3x-2 equals 3x-5 Solve for X?
Answer: no solution3x - 2 = 3x -53x - 3x - 2 = 3x - 3x - 5 (Subtract 3x from each side.)-2 = -5 Huh??When you are solving an equation, and the variable disappears, there are two possibilities:If you are left with a true statement (such as 2 = 2), then the equation is an identity, and any value of x will satisfy the equation. The number of solutions is infinite.If you are left with a false statement, as in this case, no value of x will satisfy the equation. There is no solution.
What is the equation of the line that goes through 3 1 and is parallel to the line 3x plus 5y equals 6?
Known equation: 3x+5y = 6 or y = -3/5x +6/5 Slope of equation: -3/5 Slope of parallel equation: -3/5 Parallel equation: y-1 = -3/5(x-3) => 5y = -3x+14 Parallel equation in its general form: 3x+5y-14 = 0
3x plus 5 equals 20 solve equation?
3x + 5 = 20 Subtract '5' from both sides 3x = 15 Divide both sides by '3' x = 5 The answer!!!!!
