Answer:
+- square root of x+36
Step-by-step explanation:
f(x) = x^2 -36
y = x^2 -36
Exchange x and y
x = y^2 -36
Solve for y
Add 36 to each side
x+36 = y^2 -36+36
x+36 = y^2
Take the square root of each side
±sqrt(x+36) = y
±sqrt(x+36) = f^-1(x)
Continuous Compounding Variables
FV=The future value of the principal after interest has been applied
PV=The present value of the principal before interest has been applied
R=The annual rate of interest charged
T=The number of years that the interest is charged to the principal
e=2.718281828
Answer:
Its 6 units away
Step-by-step explanation:
18) Let x be the number of coins in the pouch:
3x + 3 = 9; subtract 3 from each side:
3x + - 3 = 9 -3
3x = 6 . Now divide both side by 3:
x = 2 (in each pouch we have 2 coins)
19) SAME logic:
4x + 1 = 2x + 7; subtract 1 from each side:
4x + 1 - 1 = 2x + 7 - 1
4x = 2x + 6; now subtract 2x from each side:
4x - 2x = 2x + 6 - 2x
2x = 6 and x = 3 (each pouch contains 3 coins)
It 0 maybe this and you can change it when you see it wrong because I'm not seriously with this answer so you can try and work hard to use correct answer thank you
