Seven years ago, kodi found a box of old baseball cards in the garage. since then, he has added a consistent number of cards to the collection each year. he had 52 cards in the collection after 3 years and now has 108 cards. kodi looking into his box of baseball cards. how many cards were in the original box? is this t(0) or t(1)? write the first few terms of the sequence. kodi plans to keep the collection for a long time. how many cards will the collection contain 10 years from now? write an equation that determines the number of cards in the collection after n years. what does each number in your rule represent?
The required equation is y = 14x + 10 which is the number of cards in the collection and he will have 150 cards after 10 years
What is the slope of the line?The slope of the line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
As per the question, we take the two points are (3,52) (7,108)
So slope = (108 - 52) / (7 - 3) = 56/4 = 14
y = mx + b
slope(m) = 14
Substitute the value of x = 3 and y = 52 in the equation
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b
So the original amount of cards is 10
If x represents the number of years, while y is the total number of cards.
y = 14x + 10
He began with 10 cards and has added 14 cards every year thereafter.
So after 10 years
y = 14(10) + 10
y = 140 + 10
y = 150
Therefore, he will have 150 cards after 10 years

Explain why the equation 6|x| + 25 = 15 has no solution. When one solves, they arrive at a step where |x| is equal to a negative number. Since | x| can never be negative, there is no solution. When one solves, they arrive at a step where |x| is equal to a fraction that may not be represented as an integer. Since | x| must be an integer, there is no solution. When one solves, they arrive at a step where x is equal to a negative number. Since x can never be negative inside of the absolute value bars, there is no solution. The statement is false. There is a solution.
The equation 6|x| + 25 = 15 has no solution because it implies that |x| equals a negative number after simplification, and absolute values cannot be negative.
Explanation:The equation 6|x| + 25 = 15 has no solution because the absolute value of x, denoted by |x|, represents the distance of x from zero on the number line, and as such, it can never be negative. When we solve the given equation, we isolate the absolute value on one side which gives us 6|x| = -10 after subtracting 25 from both sides. Dividing by 6, we obtain |x| = -10/6, which is a negative number. However, since an absolute value cannot equal a negative number, this indicates that there is no valid solution to the equation.
How many times as heavy is the Golden Eagle as the Red Tailed Hawk? The Golden Eagle weighs 13 9/10 lbs and the red tailed hawk weighs 3 1/2 lbs?
The Golden Eagle, weighing 13.9 lbs, is approximately 4 times as heavy as the Red Tailed Hawk, which weighs 3.5 lbs.
Explanation:To find out how many times as heavy the Golden Eagle is compared to the Red Tailed Hawk, we need to divide the weight of the Golden Eagle by the weight of the Red Tailed Hawk. The Golden Eagle weighs 13 9/10 lbs, which can be converted into an improper fraction as 139/10 or a decimal as 13.9 lbs. The Red Tailed Hawk weighs 3 1/2 lbs, which can be converted into an improper fraction as 7/2 or a decimal as 3.5 lbs.
To perform the division, we'll use the decimal form of the weights:
Golden Eagle: 13.9 lbsRed Tailed Hawk: 3.5 lbsDividing the Golden Eagle's weight by the Red Tailed Hawk's weight:
13.9 lbs ÷ 3.5 lbs = 3.9714 (approximately)
So, the Golden Eagle is approximately 4 times as heavy as the Red Tailed Hawk.
34 days to 2 weeks the ratio is
The ratio of 34 days to 2 weeks is [tex]\(\frac{34}{2 \times 7}\)[/tex].
To find the ratio of 34 days to 2 weeks, we first need to convert 2 weeks into days, since there are 7 days in a week. Therefore, 2 weeks is equivalent to [tex]\(2 \times 7\)[/tex] days, which is 14 days.
Now, we can set up the ratio of 34 days to 14 days (2 weeks):
[tex]\[ \text{Ratio} = \frac{34 \text{ days}}{14 \text{ days}} \][/tex]
To simplify this ratio, we can divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 34 and 14 is 2.
Dividing both by 2, we get:
[tex]\[ \text{Ratio} = \frac{34 \div 2}{14 \div 2} = \frac{17}{7} \][/tex]
So, the simplified ratio of 34 days to 2 weeks is [tex]\(17:7\) or \(\frac{17}{7}\)[/tex].

What is the difference of the polynomials?
Answer:
2x^3 + 2x
Step-by-step explanation:
subtract the 2 x^4's
x^3 +x^3 = 2x^3
x +x = 2x
answer is 2x^3 + 2x
The difference between the polynomials, [tex]x^4 + x^3 + x^2 + x $ and $ x^4 - x^3 + x^2 - x[/tex] is expressed as: [tex]\mathbf{2x^3 + 2x}[/tex]
Given the polynomials:
[tex]x^4 + x^3 + x^2 + x $ and $ x^4 - x^3 + x^2 - x[/tex],We are required to find their difference which can be solved as follows:
[tex](x^4 + x^3 + x^2 + x ) - ( x^4 - x^3 + x^2 - x)[/tex]
First, open the bracket by multiplying every term you have in [tex]( x^4 - x^3 + x^2 - x)[/tex] by -1:
Thus:[tex]x^4 + x^3 + x^2 + x - x^4 + x^3 - x^2 + x[/tex]
Group like terms together and add them together[tex]x^4 - x^4 + x^3 + x^3 + x^2 - x^2 + x + x\\\\\mathbf{2x^3 + 2x}[/tex]
Thus, the difference between the polynomials, [tex]x^4 + x^3 + x^2 + x $ and $ x^4 - x^3 + x^2 - x[/tex] is expressed as: [tex]\mathbf{2x^3 + 2x}[/tex]

The table shows the annual profits (in thousands of dollars) of a county fair from 2008 to 2012. What must the 2012 profit be (in hundreds of dollars) to break even over the five-year period?
Answer:
In year 2012, 0.45 thousands dollars will bring the break even for the company.
Step-by-step explanation:
The table shows the annual profits of a county fair from 2008 to 2012.
We have to calculate the profit in 2012 to get the break even over the five year period.
Total profit in four years = profit in year (2008 + 2009) = 2.5 + 1.75 = 4.25 thousand dollars
Total loss in four years = loss in year (2010 + 2011) = 3.3 + 1.4 = 4.7 thousand dollars
Net profit or loss = Net profit - net loss = 4.25 - 4.7 = -0.45
There is a net loss of 0.45 thousand dollars.
If we get a profit of 0.45 thousand dollars in year 2012, we will be in the situation of no profit and no loss (break even).
Therefore, profit of 0.45 thousands of dollars is the answer.
Line SV is an angle bisector of angle RST if angle RSV = (3x+5) and angle RST = (8x-14) find x
Answer:
x=12
Step-by-step explanation:
Line SV is an angle bisector of angle RST
<RSV = <VST
Both angles are equal
m<RSV = (3x+5)
<RSV = <VST, so m<VST = (3x+5), m<RST= 8x-14
m<RST= m<RSV +m<VST
[tex]8x-14= 3x+5+3x+5[/tex]
Combine like terms and solve for x
[tex]8x-14= 6x+10[/tex]
Subtract 6x from both sides
[tex]2x-14=10[/tex]
Add 14 on both sides
[tex]2x=24[/tex]
Divide both sides by 2
x=12
What is the radius of a circle with circumference 27 in.?
The radius of a circle with a circumference of 27 inches can be calculated using the formula for the circumference of a circle which is 2πr. Calculating this, the radius is approximately 4.3 inches.
Explanation:The subject of this question is Mathematics, more specifically, Geometry which deals with shapes, sizes and properties of figures. In this case, we are being asked to find the radius of a circle given its circumference. The circumference of a circle is calculated as 2πr, where r represents the radius and π is approximately equal to 3.14.
To find the radius (r), you would divide the circumference by 2π. Given that the circumference of the circle is 27 inches, we divide 27 by 2π (approximately 6.28). This can be further simplified to approximately 4.3 inches.
