Answer:
f(-10) = -19
f(2) = 4
f(-5) = -9
f(-1) = 1
f(8) = -5
Step-by-step explanation:
This is relatively simple if you understand the concept. All you have to do is take each number and then look at each inequality to see where it fits.
For example, if you take 2 and look at the first inequality, you see that 2 is not less than or equal to 5. Now if you look at the second inequality, you see that 2 is both greater than -5 and less than 5. Since 2 fits in the second inequality, you plug it into the second equation.
These functions where you have to see where the x-value fits are called piecewise functions and you will see them a lot in higher level math.
(disclaimer: I evaluated the numbers quickly, so I would doublecheck it, but I am pretty sure I didn't mess up)
Answer:
Mr. Lee takes home 9 kg of chocolate.
Mrs. Scarlet takes home 6kg of chocolate.
Step-by-step explanation:
Mr. Lee has a family of 6 people, and Mrs. Scarlett has a family of 4 people.
Together, the total number of people is 6 + 4 = 10
If we divide evenly the chocolate between all 10, then each one gets the same amount.
Then we need to do the quotient:
15kg/10 = 1.5kg
This means that each person gets 1.5kg of chocolate.
And Mr. Lee has 6 on his family, then the amount of chocolate that Mr. Lee takes home is 6 times 1.5 kg
6*1.5kg = 9kg
Mr. Lee takes home 9 kg of chocolate.
Mrs. Scarlett has a family of 4 people, then she takes home 4 times 1.5kg of chocolate, this is:
4*1.5kg = 6kg
Mrs. Scarlet takes home 6kg of chocolate.
