Harlamova29_29 [7]3 years ago
7 0

Answer:

x = 10, y = 0

Step-by-step explanation:

x + 2y = 10

x = 10 - 2y <em>(</em><em>B</em><em>r</em><em>i</em><em>n</em><em>g</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>2</em><em>y</em><em> </em><em>t</em><em>o</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>r</em><em>i</em><em>g</em><em>h</em><em>t</em><em>)</em>

16y = -3x + 30

16y = -3(10 - 2y) + 30 <em>(</em><em>S</em><em>u</em><em>b</em><em>s</em><em>t</em><em>i</em><em>t</em><em>u</em><em>t</em><em>e</em><em> </em><em>x</em><em> </em><em>t</em><em>o</em><em> </em><em>1</em><em>0</em><em> </em><em>-</em><em> </em><em>2</em><em>y</em><em>)</em>

16y = -30 + 6y + 30 <em>(</em><em>E</em><em>x</em><em>p</em><em>a</em><em>n</em><em>d</em><em> </em><em>b</em><em>r</em><em>a</em><em>c</em><em>k</em><em>e</em><em>t</em><em>s</em><em>)</em>

10y = 0 <em>(</em><em>B</em><em>r</em><em>i</em><em>n</em><em>g</em><em> </em><em>y</em><em> </em><em>t</em><em>o</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>l</em><em>e</em><em>f</em><em>t</em><em>)</em>

<u>y</u><u> </u><u>=</u><u> </u><u>0</u>

x = 10 - 2(0) <em>(</em><em>S</em><em>u</em><em>b</em><em>s</em><em>t</em><em>i</em><em>t</em><em>u</em><em>t</em><em>e</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>0</em><em>)</em>

<u>x</u><u> </u><u>=</u><u> </u><u>1</u><u>0</u>

<u>x</u><u> </u><u>=</u><u> </u><u>1</u><u>0</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>0</u>

What's the intercepts for the equation 4x-6y-5z=60?
Rudik [331]
To find the x_i intercept, set x_j=x_k=0. By this I refer to the following procedure.

x-intercept: Set y=z=0, then you're left with 4x=60\iff x=15. Then the x-intercept is (15,0,0).

y-intercept: Set x=z=0, then -6y=60\iff y=-10. The y-intercept is (0,-10,0).

z-intercept: Set x=y=0, then -5z=60\iff z=-12. The z-intercept is (0,0,-12).

Find the Taylor series for f(x) centered at the given value of a. (Assume that f has a power series expansion. Do not show that
Kobotan [32]

Answer:

Here we just want to find the Taylor series for f(x) = ln(x), centered at the value of a (which we do not know).

Remember that the general Taylor expansion is:

f(x) = f(a) + f'(a)*(x - a) + \frac{1}{2!}*f''(a)(x -a)^2 + ...

for our function we have:

f'(x) =  1/x

f''(x) = -1/x^2

f'''(x) =  (1/2)*(1/x^3)

this is enough, now just let's write the series:

f(x) = ln(a) +  \frac{1}{a} *(x - a) - \frac{1}{2!} *\frac{1}{a^2} *(x - a)^2 + \frac{1}{3!} *\frac{1}{2*a^3} *(x - a)^3 + ....

This is the Taylor series to 3rd degree, you just need to change the value of a for the required value.
