Find the equation of the line specified.

OLga [1]

The point slope form of a straight line is y-y1 = m(x-x1)

y -(-3) = -7(x-5)

y + 3 = -7(x-5)

y = -7x + 35 - 3

y = -7x + 32

Make U the subject of the formular S=½(u+v)t

kirill [66]

Answer:

$U = \frac{2S}{t} - v$

Step-by-step explanation:

$S = \frac{1}{2} (u+v)t$

Divide S by 1/2

$2S = t(u+v)$

Divide 2S by t

$\frac{2S}{t} =u + v$

Subtract v

$U = \frac{2S}{t} - v$
