Because if you multiply numbers with the same sign you get a positive. If they have different signs, you get a negative.
Explanation: Because of the inverse of a positive is that positive number and back again.
Example: -2 - 2 = 0[ Also zero pairs ]
0 is positive

Answers
Answer:
25:26
Step-by-step explanation:
You mean the ratio?
Let's simplify the speed skater first. 500 meter in 40 second to x meter in 1 second. 500/40=12.5 meters per seconds
Cheetah:260/10=26 meters per seconds
Let's make this into a integer

Mallory puts $1.00 in a jar. The following week, she puts 2 times that original amount in the jar. For each of the next six weeks, Mallory continues to double the amout of money she places in her savings jar each week.
Determine if the relationship is linear or nonlinear. Explain your choice using examples with ordered pairs. (week, amount)
Answers
We want to see if the relationship between the number of weeks and the money put in the jar is linear or not, we will see that this is not a linear equation (it is exponential).
So a linear relation is something like:
y = a*x + b
Note that for any value of x, an increase of 1 unit gives:
y = a*(x+ 1) + b = (a*x + b) + a
So for increases of 1 unit in the x-value, we have increases of "a" units on the y-value.
In the given situation we have:
In week 1 she puts $1.00 in the jar.In week 2 she puts $2.00 in the jar (now the jar has $3.00 in it)In week 3 she puts $4.00 in the jar (now the jar has $7.00 on it)In week 4 she puts $8.00 in the jar (now the jar has $15.00 on it)and so on.
Writing that as points we have:
(1, $1)
(2, $3)
(3, $7)
(4, $15)
Notice that for equal increases in the x-value, (increases of 1 unit) we don't equal increases in the y-value (first increases by $2, then by $4, etc...) So this is not a linear equation, this is actually exponential.

The relationship of the ordered pair that represents Mallory savings is a nonlinear relationship.
Let x represents the number of weeks, and y represents the amount put in the jar, each week.
So, we have the following highlights for 6 weeks.
Week 1: (1, 1)Week 2: (2,2)Week 3: (3,4)Week 4: (4,8)Week 5: (5,16)Week 6: (6,32)The ordered pairs can then be represented as:
[tex](x,y) = (1,1)(2,2)(3,4)(4,8)(5,16)(6,32)[/tex]
As the x values increase, the y values increase too, but the y values do not increase at a constant rate.
This means that the relationship is not linear; it is an exponential relationship.
Hence, the relationship is a nonlinear relationship.

Shaun is painting a fence. After finishing three-eighths of the length of the fence he finds that
he has painted 15 feet. Let f be the total length of the fence, set up an equation like one of
those in 4(b) and solve to find f. Use either of the two methods.
Answers
Answer: F = 40
Step-by-step explanation:
*Important: I do not know what the methods mentioned in 4b are, nor do I know its equation. Please take this into account.
What we know:
3/8 is equal to 15 ftF is the total amount of fence paintedWe need to set up and solve the equationHow we do this:
Using basic division, this equation is solveable.
Process:
Divide to find 1/8 15/3 = 5 (1/8f = 5)Multiply to find total 5 x 8 = 40(1/8 x 8 = 8/8)
Solution:
F = 40
8(5) = F
Answer: x = 40
Step-by-step explanation:
let f be the total length of the fence:
(3/8)f = 15
divide both sides by 3/8
f = 15 x 8/3
f = 120/3
f = 40
N'(-10,-15) is the image of N after a dilation with a scale factor of 5/4, centered at the origin. What are the coordinates of N?
Answers
When the point N is dilated, the coordinate of N changes to N'
The coordinate of point N is (8,12)
How to determine the coordinate of NThe given parameters are:
N' = (10,15)
k = 5/4
To calculate the coordinate of N, we make use of:
N * k = N'
So, we have:
N * 5/4 = (10,15)
Multiply both sides by 4
N * 5 = (40,60)
Divide both sides by 5
N = (8,12)
Hence, the coordinate of point N is (8,12)

• At store A, 3 pounds of apples cost $12.
• At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.
• The cost of apples at store C is shown in the graph.
(don't worry about the graph I know how to do this one)
Answer the questions to find out which store's apples are the least expensive.
2. What is the unit price of apples at store B? How did you use the equation to find the unit price? (2 points)
Answers
Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.
