Answer: The two numbers are 1 and -7
1 minus -7 = 1 - (-7) = 1 + 7 = 8 .... difference
1 plus -7 = 1 + (-7) = -6 .... sum
===================================================
Explanation:
Let x and y be the two numbers. Let's say that x > y. Meaning that x is the bigger value.
They have a difference of 8 tells us that
x-y = 8
since "difference" is the result of subtraction. The term "sum" means the result of addition. Having a sum of -6 tells us
x+y = -6
We have this system of equations
[tex]\begin{cases}x-y = 8\\x+y = -6\end{cases}[/tex]
We can add the equations straight down. So we add the x terms to get x+x = 2x. The y terms add to -y+y = 0y = 0, so the y terms go away. The stuff on the right hand side adds to 8+(-6) = 2
After adding the equations straight down, we boil things down to the equation 2x = 2 which solves to x = 1, after dividing both sides by 2.
Then you'll use x = 1 to find y
x-y = 8
1-y = 8
-y = 8-1
-y = 7
y = -7
or
x+y = -6
1+y = -6
y = -6-1
y = -7
Regardless of what equation you pick, you should end up with the same y value. This helps confirm we have the correct x value.
Another way to check is to plug (x,y) = (1,-7) into both equations of the system. You should end up with true statements after simplifying fully.
So the two numbers are x = 1 and y = -7

Carmen runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?
Answer:
4.2 miles
Step-by-step explanation:
6 miles/50 minutes = x miles/35 minutes
1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5
2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:
0.6/5 = 4.2 miles/35 minutes

Function notation is a system of representing functions.
The two-way frequency table below shows data on whether Karissa had an ice cream cone and whether the day was during the week or on the weekend. Complete the following two-way table of column relative frequencies. (If necessary, round your answers to the nearest hundredth.) Weekday Weekend Had an ice cream cone 232323 454545 Did not have an ice cream cone 155155155 666 Weekday Weekend Had an ice cream cone Did not have an ice cream cone Column total 1.001.001, point, 00 1.001.001, point, 00
Answer:
Answers below
Step-by-step explanation:
0.13 0.88
0.87 0.12
Hope this helps!
The two-way column relative frequency table is,
Weekday Weekend
Had an ice cream cone 0.29 0.88
Did not have an ice - 0.87 0.11
cream cone
Total 1.00 1.00
What is two-way frequency table?"It is a way to display frequencies for two categorical variables."
"One category is represented by rows and a second category is represented by columns."
Now, We need to find the column relative frequency table.
First we find the total of each column.
Weekday Weekend
Had an ice cream cone 23 45
Did not have an ice - 155 6
cream cone
Total 178 51
Now, divide each element of column by its respective total.
Weekday Weekend
Had an ice cream cone 23/178 45/51
Did not have an ice - 155/178 6/51
cream cone
Total 178/178 51/51
Therefore, the two-way column relative frequency table would be,
Weekday Weekend
Had an ice cream cone 0.29 0.88
Did not have an ice - 0.87 0.11
cream cone
Total 1.00 1.00

Is y=2/3x+5 proportional or non-proportional
9514 1404 393
Answer:
non-proportional
Step-by-step explanation:
The "+5" means that y is not zero when x is zero. A proportional relation has no added constant. It is of the form ...
y = kx
The relation is non-proportional.

Two equivalent fractions for 2/3
Answer:
2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3. Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.

Math homework sucks...
Empire star Terrence Howard was paid $1.25 * 105 per episode filmed in season one. If Empire filmed 12 episodes in the first season, how much total salary did Terrence Howard earn?
Answer:
Terrence would have earned $1575 dollars
Step-by-step explanation:
First we multiply 1.25 by 105.
1.25 * 105 = 131.25
Next we multiply 131.25 by 12.
131.25 * 12 = 1575.
So, the answer is 1575.

2
)
(4,−2) and
(
24
,
−
17
)
?
(24,−17)? Write your answer in simplest form.
Answer:
-3/4Step-by-step explanation:
Given the coordinates (4, -2) and (24, -17), we are to find the slope of the line passing through the points
Slope = y2-y1/x2-x1
Slope = -17-(-2)/24-4
Slope = -17+2/20
Slope = -15/20
Slope = -3/4
Hence the required slope is -3/4

The answer is a:
It's the only one that cannot be simplified. A number that will divide evenly into both the numerator and denominator so it can be reduced, or The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number.
