Answer:

Step-by-step explanation:
<u>Given: </u>
line y=3x-1
point (-3,0)
<u>Write:</u> equation of the line that is perpendicular to the given and passes through the point (-3,0)
<u>Solution:</u>
The slope of the given line is 
If
is the slope of perpendicular line, then

So, the equation of the needed line is 
Find b. This line passes through the point (-3,0), so its coordinates satisfy the equation:

Step-by-step explanation:
f(x) = 9 * 81^x
When x = -1/2,
f(-1/2) = 9 * 81^(-1/2) = 9 * (1/9) = 1.
The answer is an intersect between both lines.
My answer is B and A that's my answer
Answer:
0.24 kilometres
Step-by-step explanation:
1cm represents 240000cm on actual map
therefore to get the actual representation
1km=1000000cm
? =240000cm
Do cross multiplication;
(240000cm x 1km)/1000000cm
=0.24km
