A line contains the points (80, -94) and (89, -84).
What is the slope of the line in simplified form?
Answer:
The answer is
[tex] \huge \frac{10}{9} [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(80, -94) and (89, -84)
We have
[tex]m = \frac{ - 84 - - 94}{89 - 80} = \frac{ - 84 + 94}{9} = \frac{10}{9} \\ [/tex]
We have the final answer as
[tex] \frac{10}{9} \\ [/tex]

The inverse of a conditional statement is "If a number is negative, then it has a negative cube root."
What is the contrapositive of the original conditional statement?
If a number is negative, then it does not have a negative cube root.
O If a number does not have a negative cube root, then the number is not negative.
O If a number has a negative cube root, then the number is negative.
O If a number is not negative, then it does not have a negative cube root.
Answer:
C. If a number has a negative cube root, then the number is negative.
Step-by-step explanation:
took the quiz
The inverse of the conditional statement is " If a number does not have a negative cube root, then the number is not negative. "
What is a conditional statement?A conditional statement is a type of logical statement that expresses a relationship between two propositions or statements. It typically takes the form "if p, then q" where p and q are propositions. The statement "if p, then q" is read as "if p is true, then q is true" or "p implies q".
The truth value of a conditional statement depends on the truth values of its antecedent (p) and its consequent (q). If p is true and q is true, then the conditional statement is true. If p is true and q is false, then the conditional statement is false. If p is false, then the truth value of the conditional statement is irrelevant and it is said to be vacuously true.
Given data ,
Let the statement be represented as A
Now , the inverse of the statement is A'
where A = "If a number is negative, then it has a negative cube root."
Now , the inverse of the conditional statement is
A' = " If a number does not have a negative cube root, then the number is not negative. "
Hence , the inverse is " If a number does not have a negative cube root, then the number is not negative. "

Millie left for her trip at 11:20 a.m. on Monday. She arrived at her destination Tuesday morning at 6:48 a.m. How long was she traveling?
The time she arrived at her destination is an illustration of time duration
She travelled for 19 hours, 28 minutes
How to determine the length of the trip?The question implies that we calculate the time taken to complete the trip.
From the question, we have:
Start = 11:20 am Monday
End = 6:48 am Tuesday
So, the duration is:
Duration = End - Start
Substitute known values
Duration = 6:48 am Tuesday - 11:20 am Monday
Evaluate the difference
Duration = 19 hours, 28 minutes
Hence, she travelled for 19 hours, 28 minutes

How is adding and subtracting mixed numbers similar to adding and subtracting fractions? How is adding and subtracting mixed numbers different than adding and subtracting fractions?
Give examples to explain your answer. Use your 4th grade words.
Answer:
It is similar because you have to always have the same numerator in adding or subtracting fractions. Adding fractions and subtracting mixed numbers is different because when u have a mixed number you have to simplify it to its lowest terms to make it easy to tell if it's a whole number or mixed.
example: 2 1/2 + 3/2= 4 now u know its a whole number but as a mixed number that would be 8/2
Step-by-step explanation:
Answer:
A mixed number is a fraction just with a whole number such as 1, 2, 3, and on. A regular fraction would be 5/10 and you can make that irregular so we can say if it was 15/10 then thats still a fraction but its improper and in order to make it proper you must make it a mixed number.

40/9
Answer:
40/9
Step-by-step explanation:
Use the work formula, [tex]\frac{1}{A}[/tex] + [tex]\frac{1}{B}[/tex] = [tex]\frac{1}{T}[/tex], where A is the amount of time it takes one person, B is the amount of time it takes another person, and T is the time it takes for them to work together.
Plug in the times for David and Alex alone:
[tex]\frac{1}{10}[/tex] + [tex]\frac{1}{8}[/tex] = [tex]\frac{1}{T}[/tex]
Find the least common denominator, which is 40.
[tex]\frac{4}{40}[/tex] + [tex]\frac{5}{40}[/tex] = [tex]\frac{1}{T}[/tex]
[tex]\frac{9}{40}[/tex] = [tex]\frac{1}{T}[/tex]
Cross multiply and solve for T:
9T = 40
T = 40/9
So, if they worked together, it would take them 40/9 hours
