9s+6s-12s=24... Ignore the 's' for a moment giving the sum 9+6-12=24 - This results in the answer 3 x 'something' = 24. Therefore s=8 !
Factorise to (x-1)(x-24)=0 then either x-1 = 0 or x-24 = 0 so x=1 or x=24
51 - x = 24 Add 'x' to both sides 51 -x + x = 24 + x -x + x = 0 Hence 51 = 24 + x Subtract 24 from both sides 51 - 24 = 24 - 24 + x 24 - 24 = 0 51 - 24 = x x = 27
x^2-5x-24=0 is solved by factoring. (x+3)(x-8)=0 x+3=0 x=-3 x-8=0 x=8
The answer is 0 obviously

4 6s = 4*6 = 24. As a fraction, this can be written as 24/1.
51 - x = 24 Add 'x' to both sides 51 -x + x = 24 + x -x + x = 0 Hence 51 = 24 + x Subtract 24 from both sides 51 - 24 = 24 - 24 + x 24 - 24 = 0 51 - 24 = x x = 27
x^2-5x-24=0 is solved by factoring. (x+3)(x-8)=0 x+3=0 x=-3 x-8=0 x=8
The idea is to multiply:24 x 0 = ...24 x 1 = ...24 x 2 = ...etc.
4 because 4x6=24
The answer is 0 obviously
To find the y-intercept, we set x to 0. 3*0+8y=24 8y=24 y=3 To find the x-intercept, we set y to 0. 3x+8*0=24 3x=24 x=8
x2-5x = 24 x2-5x-24 = 0 (x-8)(x+3) = 0 x = 8 or x -3
6x2-24=0 6(x2-4)=0 x= {-2,2}
The x- intercept of a line occurs when the line crosses the x axis. When this happens the corresponding y value of this point will be 0. From this we know that x-intercepts have y = 0. To find the x-intercept of a line we can plug this y value into the formula and get a corresponding x. 2x - 6y + 24 = 0 2x - 6(0) + 24 = 0 (substituting 0 for y) 2x + 24 = 0 (-6 * 0 is 0) 2x = -24 (add 24 to both sides) x = -12 (divide both sides by 2) The x-intercept of 2x - 6y + 2 = 0 is x = -12 & y = 0 or (-12, 0)
