What is the point-slope equation of a line with slope -5 that contains the point (6,3)
Luden [163]

Answer:

y-3=-5(x-6)

The equation of the line into point-slope form is equal to

y-y1=m(x-x1)

we have

m=-5

(x1,y1)=(6,3)

substitute

y-3=-5(x-6) ----> equation of the line into point-slope form

Rodrigo traveled at an average speed of 55 miles per hour for 5 hours to get from one national park to the next on his vacation.
vovangra [49]

Answer:

Distance between the national parks is 275 miles.  

Step-by-step explanation:

We have given,

Average speed of train = 55 miles per hour

Total time taken = 5 hours

We need to find the distance between the national park.

i.e Distance = Average speed × time taken

Distance = 55 × 5

Distance = 275 miles

Hence the distance between the national parks is 275 miles.

Simplify by dividing [ -3/-8] divided by 5/9 (5 points)
rewona [7]

Answer: D

Step-by-step explanation:

(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.

I think C was supposed to be -27/40 so D is the correct answer since it's positive.
