3x - (3x) - 2 = 3x + 3x - 2 {Combine like terms}
= 6x - 2
I-100I + 3x - [-4x] = 100 + 3x + 4x
= 100 + 7x
I -100 I means absolute value of 100 = 100

A new truck sells for $29,000 and depreciates 12% each year. Find the value of the truck after 10 years.
Answer:
according to the question value got less 12% each year
first of all the 12% of 29000$ = 29000÷100×12= 3480 $
in one year truck value deprecates 3480$
in 10 years it will 3480$×10 =34800$
now truck cost will be = 29000-34800$= -5000$

A sports marketing company is interested in how many hours teenagers in a town spend watching sports. They randomly select 40 teenagers in this town and ask how many hours per week they spend watching sports. The mean amount is 6.25 hours with a standard deviation of 4.33 hours. Which of the following is the 90% confidence interval for the true mean amount of time teenagers from this town watch sports?
Find the t-table here.
(4.396, 8.104)
(4.865, 7.635)
(5.097, 7.404)
(5.245, 7.256)

The 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The formula for the confidence interval is:
CI = x ± tα/2 × (s/√n)
where x is the sample mean,
s is the sample standard deviation,
n is the sample size, and
tα/2 is the t-value with (n-1) degrees of freedom and a confidence level of 90%.
From data (x) is 6.25 hours and
s= 4.33 hours.
We also know the sample size (n) is 40.
To find the t-value with (n-1) degrees of freedom and a confidence level of 90%, we can use a t-table.
For 39 degrees of freedom and a confidence level of 90%
Let us find that the t-value is 1.684.
Substituting the values we have into the formula, we get:
CI = 6.25 ± 1.684 × (4.33/√40)
CI = (5.097, 7.404)
Therefore, the 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

I would like help on this math problem please!
Answer:
4^11
Step-by-step explanation:
[(4^3)(4^4)]÷(4^1+4^-4)
using laws of indices
(4^3)(4^4)=4^(3+4)
=4^7
(4^1 +4^-4)=4^(1-4)
=4^-3
4^7/4^-3,recalling about laws of indices if the exponentials are dividiy ,you subtract the powers give their base is equal
4^7/4^-3=4^(7-(-3)
=4^(7+3)
=4^11

The height in feet,h , of a model rocket t seconds after launch is given by the equation h(t) = 3+70t-16t^2.
Answer:
speed of the rocket is 6feet
Step-by-step explanation:
Complete question
The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
Note that the average rate is also known as the speed
Average rate = h(3)-h(1)/3 - 1
h(3) = 3+70(3) - 16(3)^2
h(3) = 3 + 210 - 144
h(3) = 69
h(1) = 3+70(1) - 16(11)^2
h(1) = 3 + 70 - 16
h(1) = 73 -16
h(1) = 57
Average rate = 69-57/3-1
Average rate = 12/2
Average rate = 6ft/s
This shows that the speed of the rocket is 6feet

If you're looking for the answer for edge, its;

If t varies inversely as a and t= 2 when a = -4, what is t when a = 1/3?
1. -2 2/3
2. -24
3. - 1/6
4. -2/3
Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t = [tex]\frac{k}{a}[/tex] ← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 = [tex]\frac{k}{-4}[/tex] ( multiply both sides by - 4 )
- 8 = k
t = [tex]\frac{-8}{a}[/tex] ← equation of variation
When a = [tex]\frac{1}{3}[/tex] , then
t = [tex]\frac{-8}{\frac{1}{3} }[/tex] = - 24
