Step-by-step explanation:
You have to get the IQR to get the answer
Answer:
-3
Step-by-step explanation:
First, subtract 14 from 20. 20-14=6. And then divide -2 on each side. You then have to do 6/-2, when a postive number divides a negative, you change the sign. So you would get x=-3
Distance traveled by Robert = 292 miles
Time taken by Robert to cover this distance = 4 hours.
Now converting miles in feet.
1 mile = 5280 feet
so, 292 feet = 292 * 5280 = 1541760 feet
Now converting 4 hours in seconds.
1 hour = 3600 seconds
so, 4 hours have 3600 * 4 = 14400 seconds.
Now the question says, we have to find the speed in feet per second
equals,
= 107.067 feet per second
Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same.
If is perpendicular to each other: the slope should be the reciprocal to each other.
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4
Yes, you are correct. The answer of 3*(-7) = -21
