31 in total and the smaller one has 13. So just subtract 31-13 and it means there are 18 balls in the larger bag
Answer: 25:15
Step-by-step explanation: in the ratio 5:3 the 5 is dogs and the 3 is cats you multiply the 5 (aka the dogs) by 5 to get 25 (the amount of dogs in the shelter) when you multiply 3 by 5 you get the amount of cats which is 15, a good way to remember is what you do to one side you have to do to the other. I hope this helps.
Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).
Answer:
see explanation
Step-by-step explanation:
If f(x) and
are inverse functions, then
f(
)(x) = x
Thus substitute x =
(x) into f(x)
f(
)
= 5 (
) - 6
= x + 6 - 6
= x
Thus f(x) and
(x) are inverse functions
