Answer:
1) is equivalent multiply by 6
2) is equivalent multiply by 2 to 5/2
This number is three billion, five hundred fifty-two million, three hundred eight thousand, seven hundred twenty-five.
The second 5 (from the left) is in the ten millions place. It has a value of 50,000,000.
Answer:
4
Step-by-step explanation:
the absolute value of -7 is seven and the absolute value of 3 is 3.
7-3=4
F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8
f^-1(4) = 2(4) - 8
f^-1(4) = 0
