What is the answer to the rational expression 2x plus 3 over 10x squared plus 21x plus 9?
(2x+3)/(10x2+21x+9)Factor the quadratic expression in the denominator:(2x+3)/(5x+3)(2x+3)which becomes:1/(5x+3) or (5x+3)-1
What is the rate of change for the linear function y equals 2x plus 3?
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
What is 11 over 2x minus 3 over x?
5/2x
What is the rate of change for the liner function y -2x-3?
If you mean: y = -2x-3 then the slope is -2 and the y intercept is -3
Is the fraction 7 over 3 rational or irrational?
Rational

What is equal to the rational expression when x 5 or negative 3 x2 plus x-6 over x2-2x-15?
When x = -3
How do you rewrite as a function of x using function notation for 2x plus 3y equals 4?
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
How do you factor 6x2-7x-35?
Since the discriminant, b2-4ac is not a perfect square, there are no rational roots and so these are no rational factors.
If a function rule is 2x - 3 what is the output for 3?
Where Y = 2x-3, the output for x = 3 is Y = 3. 2x - 3 = 2(3)-3 = 6-3 = 3
What is the rate of change for the linear function y equals 2x plus 3?
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
What is 11 over 2x minus 3 over x?
5/2x
What is the discontinuity and zero of the function fx the quantity of 2 x squared plus 5 x minus 12 all over x plus 4?
f(x) = (2x^2 + 5x - 12)/(x + 4) as given, is not defined when the denominator is 0 ie when x + 4 = 0 or x = -4. However, 2x^2 + 5x - 12 = (x + 4)*(2x - 3) so that the function can be simplified to (x + 4)*(2x - 3)/(x + 4) = 2x - 3 This has a zero when 2x - 3 = 0 ie 2x = 3 or x = 1.5
What is the rate of change for the liner function y -2x-3?
If you mean: y = -2x-3 then the slope is -2 and the y intercept is -3
