What else can I help you with?
Which is the solution set for 3x2 - 4x - 15 equals 0?
3x2-4x-15 = 0 (3x+5)(x-3) = 0 x = -5/3 or x = 3
How do you solve 3x2 x-4 equals 0?
3x2+x-4 = 0 (3x+4)(x-1) = 0 Solutions: x = 1 and x = -4/3 By using the quadratic equation formula.
What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.
What -19 x - 30 equals?
-49
If 19 percent of x equals 45?
x = 45 x 100/19 = 236.84
What is the value of x in this equation y equals 3x2?
x = +/- sqrt(y/3)
What is the absolute value of -19?
The absolute value of 19 is 19. If x is positive , absolute x equals x.
What is the value of x in x plus 10 equals 19?
x + 10 = 19 x = 19 - 10 x = 9
Can you solve 3x2-x equals -1?
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
What is the value of 3x2 - y2 if x equals -1 and y equals 3?
x = -1y = 33x2 - y2 = 3 (-1)2 - (3)2 = 3 (1) - 9 = -6
