x2 - 9x = -8
∴ x2 - 9x + 8 = 0
∴ (x - 1)(x - 8) = 0
You can then solve it as well:
∴ x ∈ {1, 8}

What are the points of intersection of the curves y equals x2 -7x plus 8 and y equals -x2 plus 9x -6 showing work?
If: y = x2-7x+8 and y = -x2+9x-6 Then: x2-7x+8 = -x2+9x-6 So: 2x2-16x+14 = 0 => x2-8x+7 = 0 Therefore: x = 1 and x = 7 By substitution: x =1, y = 2 and x = 7, y = 8 Points of intersection: (1, 2) and (7, 8)

How do you factor x2 - 9x -8?
I think this question needs rewording. Maybe like 2x-9x-8 (144 as in a normal maths question)? Or x2x-9x-8 (x144, like a magnifiyer strength). Another rewording option is 2(-9x-8). This equals -18x-16=288 (remember a minus times a minus is a plus) === ===
What is 9x-8 equals 46?
9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6
How do you solve 44 equals 9x plus 8?
44 = 9x +8 36=9x 4=x
What are the points of intersection of the following parabolas y equals x2 -7x plus 8 and y equals -x2 plus 9x -6?
y = x2 - 7x + 8 y = -x2 + 9x - 6 subtract the 2nd from the 1st equation 0 = 2x2 - 16x + 14 simplify 0 = x2 - 8x + 7 factor it, since 7 = (-1)(-7) and -1 - 7 = -8 0 = (x - 1)(x - 7) let each factor equal to zero x - 1 = 0 or x - 7 = 0 solve for x thus, x = 1 and x = 7. Chose one of the equation and substitute x with 1, and 7 to find the corresponding y-values. y = x2 - 7x + 8 y = (1)2 - 7(1) + 8 = 1 - 7 + 8 = 2; (1, 2) intersection point y = (7)2 - 7(7) + 8 = 49 - 49 + 8 = 8; (7, 8) intersection point
What is the answer to 9x minus 4 equals 7x plus 8?
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
