City A had a population of 175,000 residents in 2018. The population is increasing at a rate of 10% per year. City B has a popul

ation that can be modeled B(t) = 350,000(0.97)t where t represents the number of years since 2018.
What is the initial population of City A?
What is the growth rate of City A?
What function model for the population of City B?
Does the model for B(t) represent an exponential growth or decay?

The solution to the equation is x = 1.62

<h3>How to solve the equation?</h3>

The equation is given as:

x =\sqrt{x\ -\ \frac{1}{x}}+\sqrt{1-\ \frac{1}{x}}

Next, we split the equations as follows:

y = x

y =\sqrt{x\ -\ \frac{1}{x}}+\sqrt{1-\ \frac{1}{x}}

Next, we graph the equations (see attachment)

From the attached graph, the equations intersect at

(x, y)= (1.62, 1.62)

Remove the y value

x = 1.62

Hence, the solution to the equation is x = 1.62

JANE, ANDRE, AND MARIA PICK APLLES. ANDRE PICKS THREE TIMES AS MANY POUNDS AS MARIA. JANE PICKS TWO TIMES AS MANY POUNDS AS ANDR
bekas [8.4K]
<span>Okay so let x = the amount of apples that Maria picks.
Andre picks three times as much as Maria, so amount Andre picks = 3x

Jane picks two times as much as Andre, and Andre = 3x So Jane = 2(3x), = 6x
</span><span>All of these added together should give 840.
</span>
<span>x + 3x + 6x = 840
</span><span>10x = 840.
</span><span>x = 84
</span><span>Therefore, Maria picked 84 pounds of apples
Andre picked 3x = 3 x 84 = 252 pounds of apples.
Jane picked 6x = 6 x 84 = 504 pounds of apples.</span>

How is the graph of y = (x + 1)^2- 5 transformed from the graph of y=x^2?
Ainat [17]

\text{Hi there! :D}

\boxed{\text{There is a horizontal shift of 1 unit left and 5 units down.}}

\text{Recall that the transformations form of a quadratic function is:}\\\\y = \pm a(b(x-h))+k \text{ where:}\\\\a = \text{ vertical stretch/compression}\\\\b = \text{ horizontal stretch/compression}\\\\h = \text{ shift left/right}\\\\k = \text{ shift up/down}\\\\\text{Therefore, in this instance:}\\\\h = -1\\\\k = -5, \text{ so:}\\\\\text{There is a horizontal shift of 1 unit left and 5 units down.}

are the graphs of the lines in the pair parallel? explain. y equals two thirds x minus 17. 4 x minus 6 y equals negative 6. a. n
nasty-shy [4]
The slope of the line is the quotient when the negative of the numerical coefficient of x is divided by the numerical coefficient of y. The slope of the first line is 2/3 and that of the second line is -4/-6 or 2/3. Thus, the answer is letter C.
