Answer:1.56
Step-by-step explanation:
For constant of proportionality of k,
y=(1/k)*x
If y =9,
9=7/k
K=7/9=0.78
y=0.78x
y=0.78*2=1.56
When x
Answer:
V≈4624.42
Step-by-step explanation:
the difference from 40000 to the future value in 2020, namely 5 years later is simply the yield or interest amount.

Step-by-step explanation:
y > -15
y is bigger than -15
= -14 , -13 , -12 , -11 , -10 , etc . . .
A = 1/2 (b x h)
A = 1/2(12.5 x 2.4)
A = 1/2(30)
A = 15
