x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
Answer:
a) Not parallel to y-axis
b) Not parallel to y-axis
c) Parallel to y-axis
Step-by-step explanation:
The best way to check whether a line passing through two points is parlle to y-axis is by plotting them on graph.
The equation of line:
a) The line joining the points (4,12) and ( 6,12) is not parallel to y-axis.
It is parallel to x-axis. Another two points that can lie on this line are : (5,12) and (,12).
b) The line joining the points is not parallel to y-axis.
Equation of line:
Another points that could be lie on this line are (0.6,2) and (0.25,1.475)
c) The line joining the points is parallel to y-axis because points have the same x-coordinate.
Another points that could be lie on this line are (0.8,2) and (0.8,2.1)
The ratio is (saturated fat) : (total fat) -----
6 grams : 9 grams -----
Divide both sides by 3 -----
6/3 grams : 9/3 grams -----
2 grams : 3 grams -----
2:3 is the ratio -----
You can also represent it in fraction form : 2/3
Before outlier : 7.25
After outlier : 4
7.25 - 4 = 3.25
So the mean decreases by 3.25 when the outlier is removed.
Answer:
r = 3 and t=5, then d = 8 is not true.
Step-by-step explanation:
Because 8 is not equal to 3*5
