Use cos^-1(0.6157) and u might find the answer
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)
500.
Solution: 210 is 42% of X
Equation: Y = P% * X
Solving our equation for X
X = Y/P%
X = 210/42%
Converting percent to decimal:
p = 42%/100 = 0.42
X = 210/0.42
X = 500
Answer:
12/5
Step-by-step explanation:
m= slope
m=Y2-Y1/X2-X1
Y2=5, Y1=-7, X2=3, X1=-2
Substitute into equation
m=5-(-7)/3-(-2)
m=5+7/3+2
m=12/5
slope is 12/5
Add 12 to both sides to get
5m= 50
divide by 5 to get
M=10
