Answer:
(3x + 2)(x-4)
Step-by-step explanation:
3x² - 10x - 8 = 0
(splitting the middle term)
3x² -12x + 2x -8 = 0
3x(x-4) + 2(x-4) = 0
(3x + 2)(x-4) = 0
(3x + 2)(x-4) is the correct answer (option a)

Vehicles generally decrease in value around 14% per year. If you buy a vehicle priced at $39,500 , this can be modeled by the equation A=39500(0.86)t . Estimate the value of the vehicle after 4 years. Round to the nearest cent and do not round until the final calculation.
Answers
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..
To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.
Substituting t = 4 into the equation:
A = 39500(0.86)^4
A ≈ 39500(0.5996)
A ≈ 23726.20
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.
This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

y = five-halves x, where y is the cost in cents for a book that is x days overdue
y = 5 x, where x is the cost in cents for a book that is y days overdue
y = 5 x, where y is the cost in cents for a book that is x days overdue
Mark this and return
Answers
Answer:
The answer would be B!
Step-by-step explanation:
In the chart if you divide the number of days over due to the cost of the fine, you get 5/2 every time. therefore, if y is the cost in cents and x is the days overdue, you would multiply x5/2 or y=5/2x, so your answer is B (y=5/2x).

Answer:
common factors: 1, 2, 4common multiples: any multiple of 168, including 168, 336, 504, 672Step-by-step explanation:
Common factors of 12 and 56 will be factors of the greatest common factor (GCF) of those numbers. That can be found several ways. One is to list the prime factors of each number, then choose the ones that are common.
12 = 2·2·3
56 = 2·2·2·7
The common factors are 2·2. Of course 1 is always a factor. So, "all common factors" are 1, 2, 4.
__
The least common multiple (LCM) can be figured using the same lists of factors. It must include all of the factors (only as many times as necessary), so will be ...
2·2·2·3·7 = 168
It can also be figured as the product of the two numbers, divided by their GCF:
12·56/4 = 168
Any "common multiple" will be a multiple of this LCM. Some common multiples of 12 and 56 are ...
1·168 = 168; 2·168 = 336; 3·168 = 504

A woman buys an item marked Rs. 3,060 after allowing a discount of 15% with 10% VAT. How much does she pay for it?
Answers
After applying a 15% discount and adding a 10% value-added tax (VAT), a woman pays a different amount than the original price of Rs. 3,060 for the item.
The original price of the item is Rs. 3,060. To calculate the final amount paid by the woman, we first apply a 15% discount to the original price. A 15% discount on Rs. 3,060 is calculated as (15/100) x 3,060 = Rs. 459. After deducting the discount, the revised price becomes Rs. 3,060 - Rs. 459 = Rs. 2,601.
Next, a 10% value-added tax (VAT) is applied to the revised price. The VAT amount is calculated as (10/100) x 2,601 = Rs. 260.1. Adding the VAT amount to the revised price, the final amount paid by the woman is Rs. 2,601 + Rs. 260.1 = Rs. 2,861.1.
Therefore, the woman pays Rs. 2,861.1 for the item after allowing a 15% discount and adding a 10% VAT.

How to solve differential equation
In this problem we find a differential equation of the form M(x) dy + N(y) dx = 0, this can be solved by separation of variables and by using integrals. First, write the differential equation:
(x - 1) dy + (y - 2) dx = 0
Second, separate the variables:
(x - 1) dy = - (y - 2) dx
- dx / (x - 1) = dy / (y - 2)
- ∫ dx / (x - 1) = ∫ dy / (y - 2)
Third, integrate the expression:

Answers

-1/2x+y-8=0, y-0, 7/6x+y-6=0
Step-by-step explanation:
First we find the slope of side AB:
6-0/0-(-3) =2
Altitude CD is perpendicular to AB:
slope of CD=-1/slope of AB = -1/2
Since the altitude CD passes through the point C(4, 6), using the point-slope form of the equation of a line, the equation of CD is:
y-6= -1/2*(x-4)
-1/2x+y-8=0
This is the required equation of the altitude from C to AB. The rest of the equations are solved in the same way. Good luck!
