Answer:
x=1
Step-by-step explanation:
log_4(x + 3) + log_4x = 1
We know that loga(b) + loga(c) = loga(bc)
log_4(x + 3)x = 1
Raise each side to the base of 4
4^log_4(x + 3)x = 4^1
(x+3)x = 4
x^2 +3x = 4
Subtract 4 from each side
x^2 +3x -4 = 0
Factor
(x+4) (x-1) =0
Using the zero product property
x= -4 x=1
But x cannot be negative since logs cannot be negative
x=1
Answer:
B or D
Step-by-step explanation:
your x point with be really close to 0 but not quite zero while your y would be 3
Lets look at the information we have:-
6.8 pounds on Sunday
8.75 pounds on Monday
How many pounds did he collect together on these 2 days?
Add:-
6.8 + 8.75 = 15.55
Dan collected 15.55 pounds of aluminum on these 2 days.
CHECK OUR WORK:-
15.55 - 8.75 = 6.8
We were RIGHT!!
So, Dan collected 15.55 pounds of aluminum on these 2 days.
Hope I helped ya!! xD
