Put the other line in point slope form...(solve for y :D )
3y=15x+9
y=5x+3, so this line has a slope of 5
For a line to be perpendicular to another the slopes have to be negative reciprocals of each other...mathematically...
s1*s2=-1
So for the other line to be perpendicular to the first:
5m=-1, m=-1/5, thus our other line (so far) is:
y=b-x/5, now we can use the point (-8,-1) to solve for the y-intercept, "b":
-1=b-(-8)/5
-1=b+8/5
-1=b+1.6
b=-2.6
So the perpendicular line that contains the point (-8,-1) is:
y=-0.2x-2.6
Answer:
The value of x for the given expression is 5 .
Step-by-step explanation:
Given expression as
+
= 
Now, arrange the equation
So,
=
- 
<u>Taking L.C.M on right hand side </u>
Or,
=
Or,
=
Or, x = 
∴ x = 5
So, The value of x = 5
Hence,The value of x for the given expression is 5 . Answer
Answer:
c
Step-by-step explanation:
1/(1/2)
2
y=2
-- The two sides of a right <u>angle</u> intersect and make the angle.
So do the sides of any other angle. So they can't be parallel.
-- No two sides of a right <u>triangle</u> ... or any other triangle ...can be parallel.
The first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42
