60 / 6 = 10 , so the commercials would have taken up 10 minutes <span />
Answer:
1) f(x) = x/8 - 7
2) f(x) = 1 - x/3
3) f(x) = 20 - 0.25x
4) f(x) = x + 7
Step-by-step explanation:
f^-1 = 8(x + 7)
x + 7 = y/8
x = y/8 - 7
f(x) = x/8 - 7
f^-1 = -3(x - 1)
y/-3 = x - 1
x = 1 - y/3
f(x) = 1 - x/3
f^-1 = 4(20 - x)
y/4 = 20 - x
x = 20 - y/4
f(x) = 20 - x/4
f(x) = 20 - 0.25x
f^-1 = x - 7
y = x - 7
x = y + 7
f(x) = x + 7
Answer:
18 or 9 13/34
Step-by-step explanation:
6 - 1 * 16 + 21 ÷ 3 4 ?
Remember the order of operations
6 - 1 * 16 + 21 ÷ 3/4
6 - 16 + 21 * 4/3
6 - 16 + 28
-10 + 28
18
or
6 - 1 * 16 + 21 ÷ 3 4 ?
remember the order of operations
6 - 16 + 21 ÷ 34
6 - 16 + 21/34
-10 + 21/34
9 13/34
You got it, both the x’s interest there
