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)
X2 - 3x - 10 equals?
If you factor x2 - 3x - 10, you'll get (x-5) (x+2). If your equation is x2 - 3x -10 = 0, then x = 5, and x = -2.
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 8 3x - 5 has no solutions?
The equation (3x + 8 = 3x - 5) has no solutions because when you simplify it, you end up with (8 = -5), which is a contradiction. This means there are no values of (x) that can satisfy the equation, indicating that the two sides are never equal. Thus, the equation is inconsistent and has no solution.
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
