Answer:
4.5
Step-by-step explanation:
The value of x that makes f(x) = -3 is ...
4/3x -9 = -3
4/3x = 6 . . . . . . add 9
x = 6(3/4) = 18/4 = 9/2 = 4.5 . . . . multiply by 3/4
f^-1(-3) = 4.5
the answer of division is 5.2
Perimeter of rectangle 2W +2L
Let L = 2W
2W + 2(2W) = 240 (number in question is unclear)
2W + 4W = 240
6W=240
W = 40
L = 40×2 = 80
dimensions 80x40
Angle 3=85 because of opposite angles. Then a straight line is 180 degrees, so subtract 85 from 180, giving us 95. Angles 2 and 3 = 95.
I believe he traveled 41.7 mph the whole trip.
1) divide 80 by 4
2) divide 65 by 3
3) add them together
4) round to nearest tenth
