Answer:
Step-by-step explanation:
To find the x-intercept, substitute 0 for y and solve for x:
Divide both sides by 2:
Add 7 to both sides to isolate x:
The x-intercept for 
is 7 at point 
.
Remove parentheses:
Subtract 2 from both sides:
The x-intercept for 
is -2 at point 
.
Finito.
Answer: after 6 years.
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car.
r represents rate at which the value is decreasing.
From the information given,
P = 3000
A = < 10000
r = 16% = 16/100 = 0.16
Therefore
10000 = 30000(1 - 0.16)^ t
1000/30000 = (0.84)^t
0.333 = (0.84)^t
Taking log of both sides to base 10
Log 0.333 = log0.84^t = tlog0.84
- 0.4772 = t × - 0.0757
t = - 0.4772/ - 0.0757 = 6.3 years
Answer:
hmm maybe 1?
Step-by-step explanation:
Answer:
I'm not 100% sure I'm right but I think x = -1
because it says "f(x)" and then it says"Find f(-1)" so that is why I think x = -1
