Answer:

(-2, -9)

explanation:

original coordinates of B: (7, 9)

use the formula: (x, y) ---> (x, -y)

  • if reflects over x-axis new coordinates: (7, -9)

If horizontally shifted there will be change in x axis,

  • new coordinates (7-9,-9) → (-2, -9)

2.What is the solution of the solution of the equation 5^3x=15? Round to the nearest ten thousandth.
sveta [45]
Hmm
remember
a^c=b can translate to log_a(b)=c
so

5^{3x}=15 can translate to log_5(15)=3x
divide both sides by 3
(1/3)log_5(15)=x
log_5(15^{1/3})=x
use calculator, if you can't use change of base formula to do it
log_a(b)= \frac{log_c(b)}{log_c(a)} so
log_5(10^{1/3})= \frac{log_{10}(15^{1/3})}{log_{10}(5)}=x
evaluate using base 10 on your calculator
