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.

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...

Solve quadratic equation: 11 m ^2 + 14m - 16 = 0 The solutions are: m1 = -2 m2= 8/11 Use formula for factoring quadratic equation: a m ^ 2 + b m + c = a(m - m1)(m - m2) Where m1 and m2 are solutions of quadratic equation In our case we have: 11 m^ 2 + 14 m - 16 = 11(m - (-2...

1.0 = 1 1.1 = 1 and 1/10 1.11 = 1 and 11/100 you can also think of the same this way: 1.0 = 1 and 0/100 1.1 = 1 and 10/100 1.11 = 1 and 11/100 thus, 1.11 is the largest of the three. Using this template, you can solve the problem.

math, really need some feedback asap.
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.

If you mean 4/x = √11 - 1/3 4/x = (3√11-1)/3 x/4 = 3/(3√11-1) x = 12/(3√11-1) or, if you insist on rational denominators, x = 12(3√11+1)/98 = 6(3√11+1)/49
