Answer:
-5/7
Step-by-step explanation:
remember slope is eqaul to rise over run.
6-11 = -5 so it rose down by 5 units
10 - 3 = 7 so it ran 7 units
thus
slope= -5/7
A) One solution: 5x +2y = 0 . . . . (any line with a different slope)
b) Two solutions: not possible
c) No solutions: 5x -2y = 0 . . . . (any different line with the same slope)
d) Infinitely many solutions: 10x -4y = 6 . . . . (any other equation for the same line)
(a) From the histogram, you can see that there are 2 students with scores between 50 and 60; 3 between 60 and 70; 7 between 70 and 80; 9 between 80 and 90; and 1 between 90 and 100. So there are a total of 2 + 3 + 7 + 9 + 1 = 22 students.
(b) This is entirely up to whoever constructed the histogram to begin with... It's ambiguous as to which of the groups contains students with a score of exactly 60 - are they placed in the 50-60 group, or in the 60-70 group?
On the other hand, if a student gets a score of 100, then they would certainly be put in the 90-100 group. So for the sake of consistency, you should probably assume that the groups are assigned as follows:
50 ≤ score ≤ 60 ==> 50-60
60 < score ≤ 70 ==> 60-70
70 < score ≤ 80 ==> 70-80
80 < score ≤ 90 ==> 80-90
90 < score ≤ 100 ==> 90-100
Then a student who scored a 60 should be added to the 50-60 category.
The statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 - 27 is less than 29
<h3>What is an inequality?</h3>
An inequality can be defined as a relation which makes an unequal comparison between two numbers or mathematical expressions.
It is used most often to compare two numbers on the number line by their size
The information given be represented as;
Now, let's find the difference from the left side
We have;
From this, we can see that the statement is wrong as - 29 is neither greater than or equal to 29
The correct statement should be; 8 - 27 is less than 29
Thus, the statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 - 27 is less than 29
