2(x - 3) = (x - 1) + 7

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms [Addition]:                                                                        2(x - 3) = x + 6
  2. [Distributive Property] Distribute 2:                                                                 2x - 6 = x + 6
  3. [Addition Property of Equality] Add 6 on both sides:                                    2x = x + 12
  4. [Subtraction Property of Equality] Subtract <em>x</em> on both sides:                         x = 12

Two numbers (represented by A and B) when multiplied together produce a maximum value. Two times the first number (A) plus one t
marusya05 [52]

Maximize U=ab subject to 2a+b=48

b = 48-2a

U = ab = a(48-2a)

U = -2(a^2 - 24 a) =-2(a^2 - 24 a + 144) + 2(144) = -2(a-12)^2+288

That's clearly maximum when the squared term is zero, so

a=12

b=48-2(12) = 24

U=12(24)=288

Answer: a=12, b=24, max 288

Use the definition mtan=lim
Leokris [45]

(a) mtan refers to the slope of the tangent line. Given <em>f(x)</em> = 9 + 7<em>x</em> ², compute the difference quotient:

\dfrac{f(x+h)-f(x)}h = \dfrac{(9+7(x+h)^2)-(9+7x^2)}h = \dfrac{(9+7x^2+14xh+7h^2)-9-7x^2}h = \dfrac{14xh+7h^2}h

Then as <em>h</em> approaches 0 - bearing in mind that we're specifically considering <em>h</em> <em>near</em> 0, and not <em>h</em> = 0 - we can eliminate the factor of <em>h</em> in the numerator and denominator, so that

m_{\rm tan} = \displaystyle \lim_{h\to0}\frac{f(x+h)-f(x)}h = \lim_{h\to0}\frac{14xh+7h^2}h = \lim_{h\to0}(14x+7h) = 14x

and so the slope of the line at <em>P</em> (0, 9), for which we take <em>x</em> = 0, is 0.

(b) The equation of the tangent line is then <em>y</em> = 9.
