2 is the slope so the slope perpendicular to that is -1/2 (negative reciprocal)
-5=-1/2(9) 9*-1/2=-4.5 and -4.5 - 0.5 = -5 so the equation for the line is y=-1/2x -0.5
Answer: here is an example in the screenshot
it is A,B,C, or D
Step-by-step explanation:
For a given perimeter, the area will be maximized when all the sides are the same length, which makes it actually a square. A square is still a rectangle, though! So, if you know the perimeter, divide it by four to determine the length of each side. Then multiply the length times the width to get the area.
BTW U CAN USE A CALCULATOR
The first one on the right
If b is greater, then it will be to the right of a
Answer:
1.4 hour, or 1 hr 24 min
Step-by-step explanation:
The trains separate at the rate (80 + 90) mph.
Recall that distance = rate times time, or time = distance / rate.
238 mi
Here, the elapsed time is -------------- = 1.4 hr, or 1 hr 24 min
170 mph
Answer:
In order, they would be:
-4.45 min, -1.8 min, -(1 + 2/3) min, -1.375 min
Step-by-step explanation:
Enjoy :)
