Find three solutions for this linear function and choose the correct graph by clicking on it. F -1(x) if F(x) = x + 3
algol13

Answer:

[1,2], [2,1], [3,0]

Step-by-step explanation:

To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.

From our graph(attached) we multiply any three solutions by a -1:

F-1(x)\\\\#For \ x=1\\F-1(1)=-1+3=2\\\\#For \ x=2\\F-1(2)=-2+3=1\\\\#For \ x=3\\F-1(3)=-3+3=0

Hence, the 3 solutions are [1,2],[2,1],[3,0]

What is the height of a triangle when the area is 36 cm and the base is 6 cm
pentagon [3]

Answer:

h = 12 cm

Step-by-step explanation:

Use the formula for area of a triangle A = (1/2)bh,   where b is the base, and h is the height.

Plug in the given information of A = 36, and b = 6, then solve for h

36 = (1/2)(6)h

  36 = 3h        (one half of 6 is 3     (1/2)(6) = 3     )

    12 = h        (divide both sides by 3 to isolate h)
