I would say Yes, but it could be wrong
So in order to find the correct answer, we can just easily plug in the values to check which ordered pair matches the given inequality above. So based on my solutions, the correct answer would be the last pair.
<span> y − 2x ≤ 1
0 - 2(5)</span> ≤ 1
0-10 ≤ 1
-10 ≤ 1
Hope this answer helps.
Answer:
D
Step-by-step explanation:
General Equation: y = mx + b
You need two pieces of data to solve this.
When x = 1, y = 8
8 = 1x + b
When x = -1, y = 3
3 = - x + b
==================
8 = x + b
3 = -x + b If we add we get b so let's add.
11 =2b Divide by 2
11/2 = b
==================
y = mx + b
y = mx + 11/2 Now we can solve for m
3 = -m + 11/2 Subtract 11/2
3 - 11/2 = - m
- 2 1/2 = -m multiply by - 1
2 1/2 = m
m = 5/2
The answer is D
Answer:
Step-by-step explanation:
Time varies inversely with speed if the distance is constant. This means that if speed increases, the time it will take to cover the same distance will reduce
t = k/s
Where t = time
k = constant of inverse proportionality
s = speed
It takes James 4 hours to get to his destination when he travels at 65 miles per hour
4 = k/65
k = 65×4 = 260
t = 260/s
If he drove 15 miles/ hour faster, the new speed is 65 + 15 = 80miles/hour.
The time it will take him is
t = 260/s
t = 260/80 = 3.25 hours
The amount of time he would save is
4 hours - 3.25 hours = 0.75 hours
Converting 0.75 hours to minutes, we multiply by 60
Amount if time saved in minutes = 0.75×60 = 45 minutes
