Answer:

11. 9h

12. 5h 35 min

13. 3h 48min

Step-by-step explanation:

11.

here,

time elapsed = ∆t = final time - initial time

= 7 pm - 10 am

= (12+7) h - 10 h {turn pm into am by adding 12 and converting both into hour and min}

= 9 h

12.

similarly,

time elapsed = ∆t = final time - initial time

= 11 h 20 min - 5 h 45 min

= 5 h 35 min

13.

similarly,

time elapsed = ∆t = final time - initial time

= 9 h 48min - 6 h

= 3h 58min

I HOPE IT HELPED YOU!

Answer:

11. 9hrs

12. 5hrs 35min

13. 3hrs 48 min

Step-by-step explanation:

Makes it a bit easier if you convert to 24 hr time.

11. 10 - 19 is 9hrs

12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min

13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min

(0,1) (3,-8) linear equation
Dmitry [639]

Answer:

The answer is

y =  - 3x + 1

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

y = mx + b

❃Incase you also forgot, The is what the slope formula is ☟

m =  \frac{y_2 - y_1 }{x_2 - x_1}

➊ First: We are going to be solving for the slope.

m =  \frac{ - 8 - 1}{3 - 0}  =  \frac{ - 9}{ \:  \:  \: 3}  =  - 3

➋Second: We find the y-intercept.

y = mx + b \\  - 8 =  - 3(3) + b \\  - 8 =  - 9 + b \\   \frac{ + 9 =  + 9 \:  \:  \:  \:  \: }{1 = b}

➌Third: Plug in.

y =  - 3x + 1
