Answer:
the answer would be -4x
Step-by-step explanation:
dividing (-20xyz) by (5zy) = 3
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
f(x) represents the total number of pages Antonia has read; x represents the number of days
Answer:
x = 1
Step-by-step explanation:
Using the rules of logarithms
log
⇔ n log x
x = n ⇔ x = 
Given
3
(2x) = 3
(2x)³ = 3
(2x)³ = 2³
8x³ = 8 ( divide both sides by 8 )
x³ = 1 ( take the cube root of both sides )
x = 1
