what is the equation in standard form of a line that passes through (1,24) and has a slope of -0.6??​
Marrrta [24]

Answer:

5y+3x=123

Step-by-step explanation:

(x1,y1)=(1,24), m=-0.6

y-y1=m(x-x1)

y-24=-0.6(x-1)

y-24=-6/10(x-1)

10(y-24)=-6(x-1)

10y-240=-6x+6

10y+6x=6+240

10y+6x=246

divide by through by 2

5y+3x=123

2. Ross started walking his dog'at 3:15.
poizon [28]

Answer:

It may be 3 : 45.

Step-by-step explanation:

Ross started walking his dog at 3 : 15 and finished before 4 : 00.

Therefore, there is a gap of 45 minutes between 3 : 15 and 4 : 00.

So, Ross walked with his dog for less than 45 minutes.

Therefore, Ross could have finished walking his dog at any time before 4 : 00 and it may be 3 : 45. (Answer)
