What is the answer to this equation 25x2-5x-20?
is the x a variable? because it would be impossible to solve with that information. in not then 150 25*2-5*-20 50--100 (negative and negative equal positive) 150 25x2 - 5x - 20 = 0 (5x + 1)(5x - 5) = 0 therefore; x = -1, or x = 1/5
How do you solve 5x plus 1 equals 20?
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
What is the X intercept of 5X plus 2Y equals 20?
To find the x-intercept, set y equal to zero in the equation 5x + 2y = 20. Then solve for x: 5x + 2(0) = 20. Simplifying, 5x = 20. Dividing both sides by 5, x = 4. Therefore, the x-intercept is (4, 0).
How do you solve 5x plus 2 equals 22?
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
How do you find the x and y intercept of -5x plus 10y equals 20?
Basically, the x-intercept is what x equals when y=0, and the y-intercept is what y equals when x=0. To find the x intercept, set y equal to 0. -5x+10(0)=20 -5x+0=20 -5x=20 divide both sides by -5 x=-4 so the x intercept is (-4,0) To find the y intercept, set x equal to 0. -5(0)+10y=20 0+10y=20 10y=20 divide both sides by 10 y=2 so the y intercept is (0,2)
