Answer:
2x + 5
Step-by-step explanation:
If I take your problem statement literally, you want to ADD x + 1 and x + 4.
That's what "and" means in this context.
Adding x + 1 and x + 4 results in 2x + 5 (answer)
We have that
1/16 = 64<span>^x
applying log both sides
log(1/16)=log(</span>64^x)
log 1-log16=x*log64
-log 16=x*log 64
divide by log 64 both sides
x=-log 16/log 64
log 16=log 2^4-----> 4*log 2
log 64=log 2^6-----> 6*log 2
-log 16/log 64=(-4*log 2)/(6*log 2)-----> -4/6------> -2/3
the answer is
x=-2/3
Answer:
2) D. y = 1,400 + 400m
Step-by-step explanation:
she starts the first month with the initial amount of 1400. this 1400 doesn't repeat monthly, so it isn't multiplied to anything. the 400m represents the 400 being added every month.
Answer:
(x - 2)² + (y + 3)² = 9
Step-by-step explanation:
(x - h)² + (y - k)² = r²
(x - 2)² + (y - (-3))² = 3²
(x - 2)² + (y + 3)² = 9
