Answer:

2x^2+2x+2 or 2(x^2+x+1)

Step-by-step explanation:

C = 2x^2+5x-1

D = x-1

C-3D = (2x^2+5x-1) - 3 * (x-1) =2x^2+5x-1-3x+3 =2x^2+2x+2 = 2(x^2+x+1)

If y varies directly as x and y-21 when x<br> is 7, find x when y = -5.

klasskru [66]

Step-by-step explanation:

Since, y varies directly as x:

$\therefore \: y = kx..(1) \\ (k = constant \: of \: proportionality) \\ at \: y = 21 \: and \: x = 7 \\ 21 = k \times 7 \\ k = \frac{21}{7} = 3 \\ plugging \: k = 3 \: in \: equation \: (1) \\ y = 3x..(2) \\ plugging \: \: y = - 5 \: in \: (2)\\ - 5 = 3x \\ x = \frac{ - 5}{3} \\ \: \: \: \: \: \: \huge \red{ \boxed{x = - \frac{5}{3} }}$
