20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
How does y equals 4x2 plus 21x look in a graph?
It is a parabola with its vertex at the origin and the arms going upwards.
7x plus 7 equals 28 x equals?
7x+7=28x 28x-7x=7 21x=7 x=3
Is 7x plus 2y equals 16 and -21x-6y equals 24 a no solution?
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
What is the factored form of y equals 3x plus 21x squared?
y = 3x + 21x2 = 3x(1 + 7x)
What is 21x equals 6x plus 30?
234 it is not the answer
What is the answer to 21x plus 452 equals 32-84x?
21x+452 = 32-84x 21x+84x = 32-452 105x = -420 x = -4
What is the answer to 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
How do you factor 20x squared -5 equals 21x?
Make it equal zero by subtracting 21x from both sides. 20x2 - 21x - 5 factors to (4x - 5)(5x + 1)
What does x equal when x plus 20x equals to 60000?
x+20x = 60000 21x = 60000 x = 60000/21 = 2857.'142857' recurring
What answer 21x plus 12x - 2 equals?
21x + 12x -2 = 0 33x -2 = 0 33x = 2 x = 2/33 x = 0.06
How does y equals 4x2 plus 21x look in a graph?
It is a parabola with its vertex at the origin and the arms going upwards.
7x plus 7 equals 28 x equals?
7x+7=28x 28x-7x=7 21x=7 x=3
Is 7x plus 2y equals 16 and -21x-6y equals 24 a no solution?
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
What is the answer 21x plus 12x - 2 equals?
I'm assuming that your solving for X. 21x + 12x - 2 = 0 33x - 2 = 0 33x = 2 x = 2/33 x =.06
What is the factored form of y equals 3x plus 21x squared?
y = 3x + 21x2 = 3x(1 + 7x)
What type of linear system is 7x plus 2y equals 16 -21x-6y equals 24?
Do you mean 7x+2y = 16 and 21x-6y = 24? If so then it is simultaneous equation with the solution being: x = 12/7 and y = 2
