Answer: Choice D (aka 4th option)

C ' (-8, 1)

D ' (-6, 5)

E ' (-2, 4)

===========================================================

Explanation:

The x axis reflection rule is (x,y) \to (x,-y)

x stays the same while y flips in sign (positive to negative, or vice versa).

  • A point like C(-8, -1) will reflect to C ' (-8, 1)
  • The point D(-6, -5) reflects to D ' (-6, 5)
  • Lastly, the point E(-2, -4) reflects to E ' (-2, 4)

All of this points to Choice D as the final answer.

Answer:

last option is correct

Step-by-step explanation:

use formula of reflection over x axis .

The coordinates of C , D , E are (-8 , -1) , (-6 , -5) , (-2 , -4) respectively.

formula :

(x , y) = (x  -y)

C(-8 , -1) = C'(-8 , 1)

D(-6 , -5) = D'(-6 , 5)

E(-2 , -4) = E'(-2 , 4)

2. Margie Spencer wants to have $100,000 in her savings account in 20 years. If her account pays 6.6% annual
WITCHER [35]

~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$100000\\ P=\textit{original amount deposited}\\ r=rate\to 6.6\%\to \frac{6.6}{100}\dotfill &0.066\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{semiannually, thus two} \end{array}\dotfill &2\\ t=years\dotfill &20 \end{cases}

100000=P\left(1+\frac{0.066}{2}\right)^{2\cdot 20}\implies 100000=P(1.033)^{40} \\\\\\ \cfrac{100000}{1.033^{40}}=P\implies 27288.97\approx P
