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:

Answer:
10
Step-by-step explanation:
It is 1 because a penny is worth 1 cent.
You have to multiply 4 decimal 5 * 2 and you get your answer and 0.7 * 2 and then you add up those two answers such a bit and see what you get
