Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2
Answer:
there will be 16 bags
Step-by-step explanation:
x = 3.
Plug in 3 for x in the equation
14(3) + 64
Remember to follow PEMDAS. First, multiply 3 with 14
3 x 14 = 42
Finally, add 64
42 + 64 = 106
106 is your answer

-9T means -9 x T
So if T is equivalent to 4,
you should do:
-9 x 4 = -36
J= -36
