Consider the system of differential equations dxdt=ā5ydydt=ā5x. convert this system to a second order differential equation in y by differentiating the second equation with respect to t and substituting for x from the first equation. solve the equation you obtained for y as a function of t; hence find x as a function of t. if we also require x(0)=1 and y(0)=3, what are x and y? x(t)= equation editorequation editor y(t)= equation editorequation editor

Write the equation of a line that is perpendicular to the given line and that passes through the given point. ā3x ā 6y = 17; (6, 3) y = x ā 9 y = 2x ā 9 y = ā2x ā 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y ā 5 = (x ā 1). the relationship is not linear. the relationship is linear; y ā 5 = (x ā 1). the relationship is linear; y ā 1 = (x ā 5). write an equation in point-slope form for the line through the given point with the given slope. (ā10, ā1); m = y + 10 = (x + 1) y ā 1 = (x ā 10) y ā 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | ā 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x ā 5.5 | y = | x | ā 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | ā 8 y = | x | + 8 y = | x ā 8| y = | x + 8|
