Answer:

=    -2x^2 +4x+ 16

Step-by-step explanation:

From the given equation:

(x+ 2 ) \   and  \  (-2x +8)

As a single equation, we have:

= (x + 2)  \ \times  \ ( -2x + 8) \  = 0

open brackets

\implies    -2x^2 +8x +(-4x) + 16

=    -2x^2 +4x+ 16

Tanzania [10]

Answer:

a

Step-by-step explanation:

The equation of a proportional relationship is

y = kx ← k is the constant of proportionality

Divide both sides by x

\frac{y}{x} = k

To find k use any ordered pair from the table

Using (2, \frac{5}{2} ) , then

k = \frac{2}{\frac{5}{2} } = 2 × \frac{2}{5} = \frac{4}{5}
