Answer:
(-4, 0) and (-3, 2)
Step-by-step explanation:
Substitute each value into the equation.
Since x = -4 in the first ordered pair, to find y, you just put it into the equation as x:
y = 2(-4) + 8
y = -8 + 8
y = 0
The first ordered pair is (-4, 0)
Now, do the same for the second ordered pair. Substitute 2 for the y and solve for x:
2 = 2x + 8
-6 = 2x
x = -3
The second ordered pair is (-3, 2)
I hope this helps!
Answer:
15 feet per minute.
Step-by-step explanation:
- speed = distance ÷ time
- speed = 450 feet ÷ 30 minutes
- 15 feet per minute = 450 feet ÷ 30 minutes
Notice that the sequence involves subtracting 10 units from the previous term. Then, we are in the case of an arithmetic sequence with common difference = -10, since we build the next rem by subtracting 10 from the previous. so we have:
term 1 = 42
term 2 = 42 - 10 = 32
term 3 = 32 - 10 = 22
term 4 = 22 - 10 = 12
term 5 = 12 - 10 = 2
term 6 = 2 - 10 = -8
term 7 = -8 - 10 = -18

Step-by-step explanation:
Step-by-step explanation:
to compare day 1 with day 2 :
100% = 8
1% = 100%/100
25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2
so, on day 2 he walks 8+2 = 10 laps.
on day 3 he walks then 10-1 = 9 laps.
so, now, to calculate the % decrease compared to day 2
100% = 10
1% = 100%/100 = 0.1
how many % is represented by this 1 lap he was walking less ?
1 / 1% = 1 / 0.1 = 10%
so he had a 10% decrease from day 2 to day 3.
