The answer would be the last choice
Answer:
27
Step-by-step explanation:
f(x) = 5x - 8
f(7) = 5(7) - 8 = 27
Since we are working with an equation written in scientific notation and we are dealing with a negative exponent, we are going to divide 4.7 by 10 three times.
4.7 / 10 = 0.47
0.47 / 10 = 0.047
0.047 / 10 = 0.0047
Best of Luck!
