Answer:
The slope is -
and the y intercept is 2.
Step-by-step explanation:
So, we can see that the line moves down one unit every time it progresses to the right three times. Slope is defined by change in y/change in x. For this problem, the change in y is -1 and the change in x is +3, so the slope is 
.
Now for the y intercept. The y intercept is the point where the line first passes through the y axis. In this case, it passes through 2. Your y intercept can be written in two ways; as a number (2) or as an ordered pair 
, although people usually write the number.
I hope this was helpful. Good luck!
Question 1:
<h3>Answer: The number does <u>not</u> change</h3>
Removing the zero from 0.76 leads to .76 which is the same as before. Both lead to 
in scientific notation.
Personally I prefer the zero up front to make the decimal point stand out easier. Of course it's just a preference, so its up to you to decide which you prefer.
===========================================
Question 2:
<h3>Answer: Yes the number changes</h3>
Taking the zero out of 10.25 leads to 1.25 which is definitely a different number (and smaller). Therefore, this zero is a significant digit compared to before.
28/20 in simplest form is: 7/5
70/50 in simplest form is 5/7
Because,
28/20 divided by 2 is 14/10, divided by 2 again is: 7/5
70/50 divided by 2 is 25/35, divided by 2 again is: 5/7
Answer:
6d+49.8
If looking for d=8.316 but 6 is repeated
Step-by-step explanation:
Answer:
The table C correctly shows the ratio 8:1 for each grade
Step-by-step explanation:
Let
x ----> the number of students
y ----> the number of adults
we know that
<u><em>Verify each table</em></u>
Table A
grade 6
Multiply in cross
----> is not true
Table B
grade 6
Multiply in cross
----> is not true
Table C
<u><em>grade 6</em></u>
\frac{96}{12}=\frac{8}{1}
Multiply in cross
----> is true
<u><em>grade 7</em></u>
Multiply in cross
----> is true
<u><em>grade 8</em></u>
\frac{136}{17}=\frac{8}{1}
Multiply in cross
----> is true
therefore
The table C correctly shows the ratio 8:1 for each grade
Table D
<u><em>grade 6</em></u>
Multiply in cross
----> is not true
