are you supposed to evaluate (x^2+11)/(3-x) when x=4i? If so, just plug it in: ((4i)^2+11)/(3-4i) = (-16+11)/(3-4i) = -5/(3-4i) = -5(3+4i) / (3-4i)(3+4i) = (-15 - 20i)/(9+16) = -3/5 - 4/5 i

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) ) ...

Start by converting 2 3/4 to an improper fraction. (3+2*4)/4 = 11/4 Divide 11/4 by 1/2. (11/4)/(1/2) = (11/4)*(2/1) = 11/2. Convert back to a mixed number. 11/2 = 5 1/2. The cook cannot bake half a batch of muffins. Round down to 5 batches.

Brad, you forgot the left hand sided x 11x/8=11/8 + x subtract x from both sides 3x/8=11/8 multiply by 8 3x=11 x=11/3

10x + x = 11 + 16x, so the next step is: 11x = 11 + 16x (get x-terms on the left.) -x = 11 (divide by -1.) x = 11 Is this now correct?

just start putting the words into symbols. If your age is a, (a + a/2 + a/3 + 3)*3 = 6*20+10 (11/6 a + 3)*3 = 130 11/2 a +9 = 130 11/2 a = 121 a/2 = 11 a = 22

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 11 and 2 from 19...

plug the value you found for x to determine whether or not this value is correct. Like so: 5/8(11)+1/16(11)=11/16+ 11 11x = 11 + 16x here's the next step: 11x-16x = 11 collect like terms and solve for x

0.11 * 165gal * 3.78 l/gal = 68.6 liters Since you didn't specify which is the 11%, it's hard to say which whether the 11% is gasoline or methanol. However, I suspect that the 11% is methanol, so I think you can take it from here.
