Grade is rise/run, or difference in elevation divided by the horizontal distance. If the roof rises 1.4' vertically over a horizontal distance of 11.8', the grade is 1.4/11.8=0.1186, or in percents, then multiply the above fraction by 100 to get 1.4/11.8*100=11.86%.

(y+4)/(x-1) = (7+4) / (2-1) (y+4)/(x-1) = 11 y + 4 = 11 x - 11 y = 11 x - 15 so I get none of he above unless d is a typo

I'm not sure what grade/math level you are at. Reasoning: There are two sides that are 11cm. You have 22 cm already. 76-22 will get you 54. What number adds up to 54? 25 adds up to 50, 26 adds up to 52, 27 adds up to 54. Anything higher than 27 will make it greater than 76cm. ...

X^2-12=-11 First add 11: x^2-12+11=0 Next: (x-11)(x-1)=0 Set each equal to 0: (x-11)=0 (x-1)=0 Get x alone by adding: x=11 x=1 Answer: (11,1) Check work by plugging numbers into original equation.

5/2x + 1/4x = 9/4 + x Multiply both sides by 4x 10 + 1 = 9x + 4x^2 Bring all terms to one side of the equation. 4x^2 + 9x -11 = 0 Unfortunately, this equation does not factor. To get - 11, it factors into 11 and - 1 or -11 and 1. The other side (4x^2) can factor into both 2x ...

F(x) = -x^2/7 - 2x/11 + 1/121, h = -b/2a = (2/11) / (-2/7) = -7/11. k = -(-7/11)^2/7 -2(-7/11)/11 + 1/121, k = -(49/121*1/7 + 14/11/11 + 1/121, k = -7/121 +14/121 + 1/121 = 8/121. V(h,k) = V(-7/11,8/121).
