Answer:
y = - 
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 7 when x = - 4, then
7 =
( multiply both sides by - 4 )
- 28 = k
y =
← equation of variation
When x = 5 , then
y =
= - 
2 to the 13th power = 8192
8192 divided by 8 = 1024
Answer:
22.5 years to the nearest tenth.
Step-by-step explanation:
The equation is
6000 = 4000(1 + 0.018/12)^12t where t = the number of years
(1 + 0.018/12)^12t = 1.5
1.0015^12t = 1.5
Taking logs:
12t log 1.0015 = log 1.5
12t = log 1.5 / log 1.0015
12t = 270.51
t = 22.54 years.
Answer:
it's 18
Step-by-step explanation:
because
3×9=18
so u do the same thing for 2
2×9=18
and u could reduce it to
9/14
the answer to 3 3/7÷6/7 is 4
