Solve the system of equations algebraically: x^2 +y^2 =25, y=x^2 +3

aalyn [17]

Answer:

${ \tt{ {x}^{2} + {y}^{2} = 25 - - - \{eqn(a) \}}} \\ { \tt{y = {x}^{2} + 3 - - - \{eqn(b) \} }}$

» substitute y in eqn(a) with y in eqn(b)

${ \tt{ {x}^{2} + ( {x}^{2} + 3) {}^{2} = 25}} \\ { \tt{ {x}^{2} + ( {x}^{2} + 6x + 9) = 25}} \\ { \tt{2 {x}^{2} + 6x + 9 = 25 }} \\ { \tt{2 {x}^{2} + 6x - 16 = 0}} \\ { \tt{x = 1.7 \: \: and \: \: - 4.7}}$

» Find y in eqn(b)

${ \tt{y = {x}^{2} + 3 }} \\ { \tt{y = 5.89 \: \: and \: \: 25.09}}$

A group of entomologists has determined that the population of ladybugs at a local park can be modeled by the equation y = − 1.4

Oksanka [162]

<h3>Answer:</h3>

A) 177.568 thousand.

B) 125.836 thousand.

<h3>Step-by-step explanation:</h3>

In this question, it is asking you to use the equation to find the population of ladybugs in a certain year.

Equation we're going to use:

$y = -1.437 x + 197.686$

We know that the "x" variable represents the number of years since 2010, so that means our starting year is 2010.

Lets solve the question.

Question A:

We need to find the ladybug population is 2024.

2024 is 14 years after 2010, so our "x" variable will be replaced with 14.

Your equation should look like this:

$y = -1.437 (14) + 197.686$

Now, we solve.

$y = -1.437 (14) + 197.686\\\\\text{Multiply -1.437 and 14}\\\\y=-20.118+197.686\\\\\text{Add}\\\\y=177.568$

You should get 177.568

This means that the population of ladybugs in 2024 is 177.568 thousand.

Question B:

We need to find the ladybug population is 2060.

2060 is 50 years after 2010, so the "x" variable would be replaced with 50.

Your equation should look like this:

$y = -1.437 (50) + 197.686$

Now, we solve.

$y = -1.437 (50) + 197.686\\\\\text{Multiply -1.437 and 50}\\\\y=-71.85+197.686\\\\\text{Add}\\\\y=125.836$

This means that the population of ladybugs in 2060 would be 125.836 thousand.

In this situation, choose length and width such that 12.75=l*w. writing it as a mixed number you have 51/4=sqrt51/2*sqrt51/2 or any other combination you can use.
