Answer:
9.1
Step-by-step explanation:
he needs one box
he needs 4 individuals 1.39×4=5.56
6 x.59=3.54
5.56+3.54=9.1
Beau can make 48 bags of 1 ounce trail mix because a pound equals 16 ounces so you multiply 16 times the 3 pounds she has.
Step-by-step explanation:
7x= 180-x
7x+x= 180
8x= 180
x= 22.5
the angle is 22.5
its supplementary angle is 157.5
Answer:
(a) f⁻¹(x) = 2x - 8
(b) f⁻¹(4) = 0
Step-by-step explanation:
This is usually not too difficult if you write the equation as y = f(x), then swap x and y and solve for y.
... y = (1/2)x + 4 . . . . y = f(x)
... x = (1/2)y + 4 . . . . variables swapped
... x - 4 = (1/2)y . . . . . subtract 4
... 2(x -4) = y . . . . . . multiply by 2
... y = 2x - 8 . . . . . . simplify
... f⁻¹(x) = 2x -8
____
Evaluating this for x=4, we get
... f⁻¹(4) = 2·4 - 8 = 0
