Positive times positive = positive
Positive times negative = negative
Negative times negative = positive
So basically, if there is an odd number of negatives, then it'll end up negative, with some exceptions.
So now we know it has to either be the first one or the last one.
The first one is multiplied by 0, so it can't be that one.
So it has to be the last one.

Decay means an overall decrease in the original value. Exponential equations are written in the form:
amount after time n = original amount x (decay OR increase factor)ⁿ
The value of the factor is less than one in the case of a decay.

On December 15, Jim Wright purchased a new automobile. The price was $22,800 cash, or $2,000 down plus 60 monthly payments of $388 each. Jim decided to finance the automobile for 60 months.
Based on the above information, calculate the following: (All work must be shown to get full credit)
a) Amount financed
b) Total amount of the monthly payments
c) Finance charge
d) Deferred payment price
Answers
Part A:
The amount financed is the amount he is owing after making the down payment.
Thus, the amount financed is given by the price of the new automobile minus the down payment = $22,800 - $2,000 = $20,800.
Part B:
Given that he makes a monthly payment of $388 for 60 months, thus the total amount of the monthly payments is given by $388 times 60 months = $388 x 60 = $23,280
Part C:
Given that the amount owed is $20,800 and the total monthly payment is $23,280.
The deferred payment price is the extra cost incurred by making monthly payments, this is given by $23,280 - $20,800 = $2,480.
The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Answers
Both Samuel and Helena are correct as the slope-intercept form and the point-slope form can be used to find the equation of a line given two points. The slope-intercept form is y = mx + b, while the point-slope form is y - y1 = m(x - x1). The methods vary but both are effective depending on the given information.
Explanation:Both Samuel and Helena are correct; they have mentioned different forms that can be used to find the equation of a line given two points. The slope-intercept form of a linear equation is commonly written as y = mx + b, where m represents the slope and b represents the y-intercept. The slope, m, describes the steepness of the line, and the y-intercept, b, is where the line crosses the y-axis. In contrast, the point-slope form is written as y - y1 = m(x - x1), where (x1, y1) is a specific point on the line and m is the slope. To find the slope, you take two points on the line, say, (x1, y1) and (x2, y2), and use the formula m = (y2 - y1)/(x2 - x1).
Either form will produce the equation of the line, but they require different approaches. The slope-intercept form immediately gives the y-intercept and is generally used when this information is valuable or when the graph will be drawn. Meanwhile, the point-slope form is particularly handy when you have one point on the line and the slope, as it can be used quickly without re-arranging the equation to solve for the y-intercept.

Both Samuel and Helena's methods are valid for finding the equation of a line. The slope-intercept form (y = mx + b) requires finding the y-intercept, while the point-slope form (y - y1) = m(x - x1) uses a point on the line directly. Both forms yield the same final equation.
Both Samuel and Helena are correct, but they are using different methods to find the equation of a line. The slope-intercept form and the point-slope form can both lead to the same final equation of the line, which will be consistent after simplifying. Here's a step-by-step explanation of both forms:
Slope-Intercept Form (y = mx + b)Slope-Intercept Form is given by the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
First, find the slope (m) using the formula: m = (y2 - y1) / (x2 - x1).Next, use one of the given points (x1, y1) and substitute in the found slope and coordinates to solve for b (the y-intercept).Substitute the slope and y-intercept back into the slope-intercept form.Example:
Given points (1, 2) and (3, 4):
Calculate the slope: m = (4 - 2) / (3 - 1) = 2 / 2 = 1.Use one of the points to find b: 2 = 1(1) + b; solving this, we get b = 1.Equation of the line: y = 1x + 1.Point-Slope Form (y - y1) = m(x - x1)The Point-Slope Form is given by the equation y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
First, find the slope (m) using the same formula: m = (y2 - y1) / (x2 - x1).Use one of the given points (x1, y1) and substitute in the found slope.Simplify the equation to convert it to slope-intercept form if needed.Example:
Given points (1, 2) and (3, 4):
Calculate the slope: m = (4 - 2) / (3 - 1) = 2 / 2 = 1.Select point (1, 2): y - 2 = 1(x - 1).Simplify: y - 2 = x - 1;y = x + 1.
Both forms ultimately lead to the same linear equation. Choosing which form to use depends on what information is given and personal preference.

With the wind, a jet can fly 2500 km in 2 hours 30 minutes. Against the wind, it can fly only 2000 km in the same amount of time. Find the rate of the jet in still air and the rate of the wind.
Answers
With wind DATA:
distance = 2500 km ; time = 2.5 hrs ; rate = 2500/2.5 = 100 km/h
Against the wind, it can fly only 2000km in the same time.
Against wind DATA:
distance = 2000 km ; time = 2.5 hrs ; rate = 2000/2.5 = 800 kmh
Find the rate of the jet in still air and the rate of the wind.
p + w = 100
p - w = 80
2p = 180
p = 90 kmh (plane speed in still air)
Since p+w = 100, w = 10 kmh (wind speed)

Answers
It will take [tex]\( 5.299643 \times 10^4 \)[/tex] hours for the space shuttle to reach Saturn from Earth.
To calculate the time it takes for the space shuttle to reach Saturn from Earth, we need to use the formula:
[tex]\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \][/tex]
Given:
Distance from Earth to Saturn = 1,483,900,000 km
Speed of the space shuttle = 28,000 km/h
Convert distance to kilometers in scientific notation:
[tex]\[ 1,483,900,000 = 1.4839 \times 10^9 \][/tex]
Plug values into the formula:
[tex]\[ \text{Time} = \frac{1.4839 \times 10^9 \, \text{km}}{28,000 \, \text{km/h}} \][/tex]
Calculate:
[tex]\[ \text{Time} = \frac{1.4839 \times 10^9}{28,000} \][/tex]
[tex]\[ \text{Time} = 52,996.43 \, \text{hours} \][/tex]
Convert to scientific notation:
[tex]\[ 52,996.43 = 5.299643 \times 10^4 \, \text{hours} \][/tex]
So, it will take [tex]\( 5.299643 \times 10^4 \)[/tex] hours for the space shuttle to reach Saturn from Earth.

Subtracting a negative number is the same as adding its absolute value. Hence, the expression x - (-3) is equivalent to x + 3 in mathematics.
Explanation:A negative number is equivalent to its absolute value when subtracted in mathematics. This is often referred to as the rule 'minus a negative is a positive'. Therefore, the correct answer is x + 3. This is because when you subtract -3 (which is a negative number), it is the same as adding 3. Here's the step by step explanation:
Start with the expression x - (-3). Recognize that subtracting -3 is the same as adding 3. Rewrite the expression as x + 3.This means that x - (-3) is equivalent to x + 3.
