Express the relationship between x + 2 and -2x + 8 as a single equation

aksik [14]

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

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

$= -2x^2 +4x+ 16$

The City Zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bi

Anna11 [10]

Let a and c represent, respectively, the price of an adult and a child ticket. We know that

$\begin{cases}3a+2c=78.94\\2a+3c=75.86\end{cases}$

Multiply the first equation by 3 and the second equation by 2 to get

$\begin{cases}9a+6c=236.82\\4a+6c=151.72\end{cases}$

Subtract the two equations to have

$5a=85.1 \iff a=17.02$

Plug this value in the first equation to get

$3\cdot 17.02+2c=78.94\iff 2c=27.88\iff c=13.94$
