Answer:
f-1(x) = (x - 16)/40
B
Step-by-step explanation:
Call f(x) = y
Interchange x and y
x = (5y + 2)*8 Remove the brackets
x = 40y + 16 Subtract 16 from both sides
x - 16 = 40y Interchange the left and right sides
40y = x - 16 Divide by 40
y = (x - 16)/40
f-1(x) = (x - 16)/40
Just take $1,557,555 and divide by 3. You should get 519,185 Snacks
Answer:
The answer is C
Step-by-step explanation:
As you can see, the triangle is split in to 2 right triangles. We can use this to check our work. The formula for solving a triangle is base * height all divided by two.
In this case, b = 6, and h = 4. We get 24 when we multiply them, so when we divide it by two, we get 12
Let's check using the right triangles now.
We know the base is split in to two when we make two right triangles. We can do 3 * 4 = 12/2 = 6. Now we can do 6 * 2 since there are two right triangles, once again, we get 12.
