We only need a calculator for this. But, to simplify and make sure you have a good experience here on Brainly, the answer is -0.15. All I did was find 12/80, and added the negative sign. If your issue was that you could not get the negative sign on your calculator, well, there is your answer
Question 1: C. (-4, 8]
With B, I think you assumed since there are two separate lines for the function, there must be two separate ranges. Additionally, you state that the left one has a range from -4 to 3, each non-inclusive, which is incorrect as there is a solid point at y = 3. However, the -4 non-inclusive part is correct.
Basically, this is all one function therefore there should be a single range. Since as you can see on the graph, 8 is included, the new range should be (-4, 8]. The function extends from -4, non-inclusive, to 8, inclusive. Even though there is a gap between the two parts, it is a singular function and as a whole, both are considered when calculating the range.
Question 2: C, {x | x > 10}
You are correct! x = 10 is a vertical asymptote for this function - the function will never reach this value so you should not use the "greater than or equal to" sign.
Answer:
a = 90
b = 28
c = 68
d = 22

Answer:
B. He would still need 51.50
Step-by-step explanation:
First I added up all the deposits Emilio made
so: 621.96+83.11+52.89+307.84=1065.8
then i subtract 129 from the total (1065.8)
which equals 936.8 and I add the 11.5 interest.
which equals 948.3 which is 51.70 less than 1000. Therefore, Emilio still need 51.70 in order to meet his saving accounts goal.
