Answer:

x = 3

Step-by-step explanation:

You are solving for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 14 and 4x from both sides:

-3x (-4x) + 14 (-14) = 4x (-4x) - 7 (-14)

-3x - 4x = -7 - 14

-7x = -21

Next, divide -7 from both sides of the equation:

(-7x)/-7 = (-21)/-7

x = -21/-7

x = 3

x = 3 is your answer.

For this case, the first thing we must do is define variables.

We have then:

x: altitude of the plane in feet

y: final temperature

The equation modeling the problem for this case is given by:

$y = - \frac{1.1}{1000} x + 59.7$

Thus, evaluating the function for x = 11,000 ft. Height we have:

$y = - \frac{1.1}{1000} (11000) +59.7$

$y = 47.6$

Answer:

the temperature at an altitude of 11,000 ft is 47.6 F
