Answer:

(x-y) (a+x-y)

Step-by-step explanation:

(y-x)=-(x-y)

-a(y-x) = a(x-y)

(x-y)^2 = (x-y)(x-y)

(x-y)(a + x - y)

1 point<br> Solve: 0.75 (x + 200) = 150.5 (2 – 28)<br> type your answer...

adelina 88 [10]

Answer:

$\huge \: x = - 5417.33$

Step-by-step explanation:

$0.75 (x + 200) = 150.5 (2 – 28) \\$

<u>Expand the terms and simplify</u>

That's

$0.75x + 150 = 301 - 4214 \\ 0.75x + 150 = - 3913$

Subtract 150 from both sides of the equation

$0.75x + 150 - 150 = - 3913 - 150 \\ 0.75x = - 4063$

<u>Divide both sides by 0.75</u>

$\frac{0.75x}{0.75} = - \frac{4063}{0.75} \\ x = - 5417.333333$

We have the final answer as

In 1960, the population of a town was 14 thousand people. Over the course of the next 50 years, the town grew at a rate of 30 pe

andre [41]

SOLUTIONS

Given: Assume y is the population

$\begin{gathered} t=0=1960,y=14030 \\ t=1=1961,y=14060 \\ so\text{ b = 14000} \\ so\text{ k = 30} \end{gathered}$

The town grow at the rate of 30 people per year.

$y=kt+14000$ $y=30t+14000$

(A) The population predicted to be in 2030 will be

$\begin{gathered} 2030-1960=70 \\ y=30k+14000 \\ y=30(70)+14000 \\ y=2100+14000 \\ y=16100people \end{gathered}$

(B) so when y = 15000, find t

$\begin{gathered} y=15000 \\ y=30t+14000 \\ 15000=30t+14000 \\ 15000-14000=30t \\ 1000=30t \\ t=\frac{1000}{30} \\ t\approx33 \\ t=1960+33 \\ t=1993 \end{gathered}$
