First of all , I think you meant f(x) = 1/(x+5) the difference quotient is (f(l+h) - f(6))/h = (1/(11+h) - 1/11 )/h = (11 - 11 - h)/(11(11+h) (1/h) = -1 / (11(11+h)) I notice another error is your typing you probably meant to type: ..... can be simplified to -1/(a(h+b) ) ...

f(x) = 1/(x+11) where x is not 11 or -11. It looks like it ought to be true for x=11 as well, except that at x=11, we have f(x)=0/0. So, the function is continuous on (-oo,-11) (-11,11) and (11,+oo) While the limit from the left and right at x=11 is 1, the function is not ...

A little thought should make it clear that since x is farther from 11 than from 19, 1. x is between 11 and 19 2. x > 19 If 11<x<19, x-11 = 3(19-x) x-11 = 57-3x 4x = 68 x = 17 If x > 19, x-11 = 3(x-19) x-11 = 3x-57 2x = 46 x = 23 check: 17 is 6 from ...

14x + 3x - 40 = 11 17x - 40 + 40 = 11 + 40 17x = 51 x = 3 To prove it: 14(3) + 3(3) - 40 = 11 42 + 9 - 40 = 11 51 - 40 = 11 11 = 11 Yep! It works!

1. Subtract 11 from both sides, to get rid of the 11. Then solve for p. 7p+11=-31 -11 -11 7p=-42 Then divide by 7 to get rid of the 7. p=-6 Does that help?

Multiply to get a common denominator: The common denominator must be (v+11)(v+19). Therefore, multiply each part by the missing factor to reach that denominator. v/(v+11)*(v+19)/(v+19) + 1/(v+19)*(v+11)/(v+11) = (v+11)(v+19)/((v+11)(v+19)) Now we have v(v+19)/((v+11)(v+19...

x^2 + 9x - 22 = 0 (x+11)(x-2) = 0 x = -11 or x = 2 but x is to be positive, so x = 2 then y^2 - 13y + 24 = 2 y^2 - 13y + 22 = 0 (y-11)(y-2) = 0 y = 11 or y = 2 so the sum of these y values is 11+2 = 13
