Answer:

Step-by-step explanation:

Given line is y=2x+5

By comparing it with the y=mx+b

we say that the slope of the given line is m=2

The concept is that the slope of a perpendicular line is given by -1/m.

Hence the slope of a line that is perpendicular to the given line is

-\frac{1}{2}

a construction company charges $15 per hour for debris removal , plus a one -time fee for the use of the trash dumpster.the tota
ser-zykov [4K]

Let h be the numbers of hours, f be the one-time fee and c the cost charged. The equation is

c=15h+f

Since you pay $15 per four, plus the fee. We can solve this equation for the fee:

f=c-15h

If we plug c=195 and h=9, we have

f=195-15\cdot 9=195-135=60

Which is the graph of y = 1/x?
irina1246 [14]

<u>answer:</u> the first graph

<u>explanation:</u>

it would not be the second one because it is a slope (y = mx + b) and so would be the third choice.

i don't think it would be the last one because it's going only up to 40. which the equation say only y = 1/x and it's not a big number equation.

hope this helps! ❤  from peachimin

i attached this image which is sorta similar to the the to this equation:
