Answer:
The y-intercept is at the point (0, 9).
Step-by-step explanation:
WE have the y intercept when x = 0:
-7(0) - 5y = -45
-5y = -45
y = -45/-5 = 9.
 
        
                    
             
        
        
        
Answer:
the school
Step-by-step explanation:
the point given is (4,5) so let's try to hone in on that so to speak-
with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method
seeing as how both are practically the same i'll just go with the craw before you walk method-
so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
 
        
             
        
        
        
Answer:
V = π²h
r = √V/πh
r = √13,665.28cm³/(3.14)(17cm)
r =√13,665.28/53.38 cm
r = √256 cm
r = 16 cm
 
        
             
        
        
        
Answer:
b
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange both equations into this form
x - 6y = - 30 (subtract x from both sides )
- 6y = - x - 30 ( divide all terms by - 6 )
y =  x + 5 ← in slope- intercept form
 x + 5 ← in slope- intercept form
with slope m = 
y = - 6x + 5 ← in slope- intercept form
with slope m = - 6
Parallel lines have equal slopes.
Clearly the lines are not parallel.
The product of the slope of perpendicular lines equals - 1, thus
 × - 6 = - 1
 × - 6 = - 1
Hence the lines are perpendicular → b
