Answer:
80, every 5 percent is 4 people. So every 25% is 20. 20 x 4 is 80.
Step-by-step explanation:
Answer= -54
-2(bx-5)=16
If b is 3, then it changes to -2(3x-5)=16
We want to find x, right? Then we must do -2•3x and -2(-5). The result would be -6x and 10.
Then again, the equation would change -6x+10=16
Which would be -6x=6
Is x=6/6
And then x would be 1

The formula for Average speed = 
The car travels 80 km in 1 hour.
Then the car travels 90 km in 2 hours.
And finally the car travels 76 km in 1 hour
So the total distance covered by the car = 80 + 90 + 76 = 246 km
The total time taken to cover this distance = 1 + 2 + 1 = 4 hours.
So average speed = 
The average speed of the car is 61.5 km / h
Answer:
-2
Step-by-step explanation:
-2-15
-2 +(-15)
-17
The equation of the parabola whose focus is at (7, 0) and directrix at y = -7 is
(x-7)^2 = 14(y + 7/2)
