Answer:
x = 30 and y = -34
Step-by-step explanation:
Given the following functions
(1/4)^(x+y) = 256... 1
log₄(x-y) = 3.... 2
From equation 2;
x-y = 4³
x-y = 64
x = 64 + y ... 3
Substitutw 3 into 1
From 1:
(1/4)^(x+y) = 256
(1/4)^(64+y+y) = 256
(1/4)^(64+2y) = 256
Take log₄ of both sides
64+2y log₄ (1/4) = log₄256
-(64+2y) = 4log₄4
-(64+2y) = 4
64+2y = -4
2y = -4 - 64
2y = -68
y = -34
Since
x = 64 + y .
x = 64 - 34
x = 30
Hence x = 30 and y = -34
Answer:
D $45
Step-by-step explanation:
you would take the $350 and divide it by 80 an you get 4.375 than you round that to the nearest 5th
Answer:
-18
Step-by-step explanation:
Successor of -19 = - 19 + 1 = - 18
From the picture it looks like 38 degrees still from the picture sorry if I'm wrong
let me know if the propositions they gave don't match with mine.
thanks
