Solve the following system algerbraically: y=-3(x-2) squared+4 y=-6x+16

pishuonlain [190]

$y = - 3(x - 2) ^{2} + 4$
$y = - 6x + 16$
distribute the -3 and the square into the first equation
$y = - 3x ^{2} + 12x - 8$
$y = - 6x + 16$
multiply the second equation by 2
$y = - 3x ^{2} + 12x - 8$
$y = - 12x + 32$
add the equations together
$y = - 3x ^{2} + 24$
factor out -3
$y = - 3(x ^{2} - 8)$
factor inside parenthesis
$y = - 3(x + \sqrt{8} )( x - \sqrt{8})$
refine
$y = - 3(x + 2 \sqrt{2} )(x - 2 \sqrt{2} )$

The population of Maricopa County has been increasing for the past few decades. In 2016, the Maricopa County population is appro

maria [59]

Answer: 3,965,481

Step-by-step explanation:

Given: In 2016, the Maricopa County population is approximately 3.817 million.

i.e. Initial population= 3.817 million =3,817,000

Of the population increases from the current population by 3.89 % over the next 5 years,

Population increased = 3.89% of 3,817,000

= 0.0389 (3817000)

= 148481.3 ≈ 148481

Population in 2021= 3,817,000 +148,481 =3,965,481

Hence, the population in 2021 = 3,965,481
