Solve the system <br> -2y+5z=-3<br> y=-5x-4z-5<br> x=4z+4
kow [346]
-2y + 5z = -3
y = -5x - 4z - 5
x = 4z + 4

-2(-5(4z + 4) - 4z - 5) + 5z = -3
-2(-20z - 20 - 4z - 5) + 5z = -3
-2(-20z - 4z - 20 - 5) + 5z = -3
                    -2(-24z - 25) = -3
                          48z + 50 = -3
                          <u>       - 50  - 50</u>
                                 <u>48z</u> = <u>-53</u>
                                  48      48
                                     z = -1⁵/₄₈
x = 4(-1⁵/₄₈) + 4
x = -4⁵/₁₂ + 4
x = ⁵/₁₂

y = -5(⁵/₁₂) - 4(-1⁵/₄₈) - 5
y = -2¹/₂ + 4⁵/₁₂ - 5
y = 1¹¹/₁₂ - 5
y = -3¹/₂

(x, y, z) = (⁵/₁₂, -3¹/₂, -1⁵/₄₈)

If dy/dt=-2y and if y=1 when t=0, what is the value of t for which y=1/2
gladu [14]
\bf \displaystyle \int -2t\cdot dt\implies -2\int t\cdot dt\implies -2\cdot \cfrac{t^2}{2}+C&#10;\\\\\\&#10;-t^2+C=f(x)\qquad &#10;\begin{cases}&#10;f(x)=y=1\\&#10;t=0&#10;\end{cases}\implies -0^2+C=1\implies C=1&#10;\\\\\\&#10;-t^2+1=f(x)\\\\&#10;-----------------------------\\\\&#10;-t^2+1=f(x)\qquad f(x)=\cfrac{1}{2}\implies -t^2+1=\cfrac{1}{2}&#10;\\\\\\&#10;1-\cfrac{1}{2}=t^2\implies \pm \sqrt{\cfrac{1}{2}}=t\implies \cfrac{1}{\pm \sqrt{2}}=t&#10;\\\\\\&#10;\pm \cfrac{\sqrt{2}}{2}=t\impliedby \textit{with a rationalized denominator}
