A because if he started at negative ten you would add the 10 he increased. When you add those two together you get 0.
-10+10=0
Answer:
Step-by-step explanation:
Last week, burton paid $36.80 for 11 1/2 gallons of gas. Converting 11 1/2 gallons of gas to decimal, it becomes 11.5. The rate at which Burton bought one gallon of gas last week would be
36.80/11.5 = $3.2
The cost per gallon of gas increased by 5% between last week and this week. The amount by which it increased would be
5/100 × 3.2 = 0.05 × 3.2 = $0.16
The cost of one gallon of gas for this week would be
3.2 + 0.16 = $3.36
She bought 9 1/4 gallons of gas this week. Converting 9 1/4 gallons of gas to decimal, it becomes 9.25 gallons of gas. The amount that she paid for gas this week would be
9.25 × 3.36 = $31.08
look at the whole numbers and not the tenths and hundreds and stuff.

Answer:
B
Step-by-step explanation:
From the statement, we are given a function that shows the number of cell tower users f(x) after x years, from the year 2010 to 2019, so, to solve the problem, we need to remember that the domain is equal to all the values that the variable (x for this case) could take making the function itself exist.
So, the given function is a function of years, and we know that "x" represents the years from 2010 (starting value), to 2019 (ending value) meaning that the domain is located between those two values.
Hence, the correct option is:
B. 0 ≤ x ≤ 5,000
Answer:
50
Step-by-step explanation:
- 8i = √-64
8i + 6
- -4i = -√-16
-4i + 3
[8i + 6][-4i + 3] → FOIL
>> -32i² + [24i - 24i] + 18
↑ ↑
-1 0
>>> 32 + 18 = 50
Information on Imaginary Numbers
√-1 = i
-1 = i²
-i = i³
1 = i⁴ [And every other exponent that is a multiple of 4; this cycle then repeats itself every time you go up one number at a time]
