Answer:
19. 1 do 4^5 which is 1024 then do 1024^0 which is 1
21. 0.000064 do 5^-2 which is 0.04 then do 0.04^3 which is 0.000064
23. 2.33 do 9^4 which is 6561 then do 6561^-2 which is 2.32305731 so you round it to 2.33
btw you should talk to me more
Answer:
Independent variable: c
Dependent variable: b
Step-by-step explanation:
The c is by itself meaning it is independent. :)
x/20 = 21/14 (similar proportions)
x/20 = 3/2 (simplify by canceling out a factor of 7)
x = 30
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
