The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:
or
By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X.
For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
19 comes next in the series, followed by two 21s.

A) satellites</h3><h3>D) Weather balloons</h3><h3>E) Automated weather stations</h3>
=====================================================
Explanation:
Satellites are used to measure things like the formation of storms and predicting where they will go. They provide a big picture of the climate as a whole, and they're useful for studying climate patterns.
Weather balloons are used to measure humidity, wind speed, temperature and pressure in the atmosphere. They are useful because they are very inexpensive compared to satellites, and can be made quicker.
Automated weather stations are locations where much of the same things are measured with weather balloons, though on the ground rather high in the air. In addition, weather stations will likely have a rain gauge to measure how much rain has fallen in a certain area.
Lets x is the amount of money Paul spent
y is the amount of money John spent
<span>Henry spent 3 times as much as paul = 3x
so
</span>John and paul spent $45 altogether: <span>x + y = 45
</span> john and henty spent $65 altogether: 3x+y = 65
solve the equations
3x+y = 65
x + y = 45
---------------subtract
2x = 20
x = 10
x + y = 45
y = 45 - x
y = 45 - 10
y = 35
3x = 3(10) = 30
so
Paul spent $10 (x)
John spent $ 35 (y)
Henry spent $30 (3x)
answer: John spent $ 35
double check:
$ 35 + $ 10 = $45 (<span>John and Paul spent $45 altogether)
</span>$ 35 + $30 = $65 (<span> John and Henry spent $65 altogether)</span>
Answer:
the X is jus a fill in number
Step-by-step explanation:
u have to guess the x so basically u have to see what mixed fraction equals -50
