Answer:
...
Step-by-step explanation:
The two trains the same distance from Buffalo is 20
Answer:
Reminder that is this form a(b)^x where a > 0
When b > 0 but < 1 that is a decay function
When b > 1 than its a growth function
Step-by-step explanation:
So following this you can figure out the answer
g(x)=0.3(x)
this is neither since there is no exponent (linear)
H=72(56)^t
this is growth since b = 56
A=(43)^t
this is growth since b = 43 ("a" is understood as "1")
H=5.9(0.82)^t
this is decay since b = 0.82
y=0.8(3.6)^t
this is growth since b = 3.6
f(t)=0.72(15)^t
this is growth since b = 14
A=49(8)^t
this is growth since b = 8
A) .10 d + .25 q = 7.75
B) d + q = 40
Multiplying B) by -.10
B) -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75
Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75
Correct!!
The answer is d because 12c=20 = c=65/12 divide by both sides
