Answer:
well x-(-18) x+18 but the if part is x<-18 will stay the same
Step-by-step explanation:
I hope this helps you
x=10 f(10)=|10+5|=|15|=15
x=-5 f(-5)=|-5+5|=|0|=0
x=0 f(0)=|0+5|=|5|=5
Answer:
The cost of basic cable television in the United States in the year 2020 will be $67.19.
Step-by-step explanation:
The linear function has the following format.
In which y(x) is the cost x years after 2000, y(0) is the initial cost, that is, the cost in 2000, and a is the slope(how much the cost changes in a year).
In 2000, the average monthly price for basic cable television in the United States was $29.99.
This means that 
In 2016, the average monthly price for the same basic cable television was $59.75.
2016 is 16 years after 2000. So
Write a linear function that models the cost of basic cable television in the United States for x years after 2000.
Applying y(16).
So
Use the linear function to determine the cost of basic cable television in the United States in the year 2020.
2020 is 20 years after 2000, so this is y(20).
The cost of basic cable television in the United States in the year 2020 will be $67.19.
Oscar's age = 16
Sister's age = 12
Current year: 16 / 12
Simplest form: 4 / 3 ; both are divisible by 4.
2 years after: (16 + 2) / (12 + 2) = 18 / 14 ; add two years to both numbers.
Simplest form: of 18 / 14 is 9 / 7; both are divisible by 2.

Answer: 0.5</h3>
========================================================
Explanation:
The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.
We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.
This leaves sin(B)/b
We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.
The angle opposite side c is 15 degrees, so C = 15.
The lowercase letters represent side lengths, while the uppercase letters are angles.
--------------------------
We have enough to apply the law of sines to solve for side c.
sin(B)/b = sin(C)/c
sin(105)/2 = sin(15)/c
c*sin(105) = 2*sin(15) ............. cross multiply
c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)
c = 0.53589838486224
c = 0.5
Side c is roughly 0.5 cm long.
Make sure your calculator is in degree mode.
