Answer:
5^x - 5^-x
Step-by-step explanation:
g(x) = 5^-x
h(x) = 5^x
We want h(x) - g(x)
h(x) - g(x) = 5^x - 5^-x
This cannot be simplified
Answer
8+6 x 9/-9
Step-by-step explanation:
The x is a multipcation sign
the dash is a division sign.
So.... there are 10 crayons and 8 are yellow.
This means that 8/10 of the crayons are yellow.
So the chance of picking a yellow one is 80%.
To get this, you need to do 8/10 and make it over 100, which is 80/100. Then, you turn this number into a percent by just dropping the 100 and adding a % to 80 (it's this easy if the bottom denominator is 100)
The work should look something like this;
8:10
8/10
80/100
80%
So, there is an 80% chance that the crayon you pick will be yellow. Any questions?
