Answer: approximately 5.1818 pounds per square inch (psi)

========================================================

Work Shown:

P = pressure

T = temperature

The pressure is directly proportional to the temperature, which means P = k*T where k is some constant. As T goes up, P goes up as well, and vice versa. If P goes down, then T goes down too (or vice versa). In short, P and T go up together or go down together.

We're told that 6 psi (pounds per square inch) correspond to a temperature of 440 degrees F. This means P = 6 and T = 440 pair up. Let's use this P and T pairing to find k.

P = k*T

6 = k*440

6/440 = k

k = 6/440

k = 3/220

Therefore, the equation

P = k*T

updates to

P = (3/220)*T

--------------------

The last step is to plug in T = 380 to figure out the paired value of P

P = (3/220)*T

P = (3/220)*380

P = 5.1818 approximately

Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.

Arturiano [62]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

$m = \frac {y2-y1} {x2-x1}$

We have the following points:

$(x1, y1): (- 7,25)\\(x2, y2): (- 4,13)$

Substituting the values: $m = \frac {13-25} {- 4 - (- 7)} = \frac {-12} {- 4 + 7} = \frac {-12} {3} = - 4$

Thus, the line is of the form:

$y = -4x + b$

We substitute one of the points and find "b":

$13 = -4 (-4) + b\\13 = 16 + b\\b = 13-16 = -3$

Finally we have to:

$y = -4x-3$

Answer:

The equation es $y = -4x-3$

Akimi4 [234]

Answer:

Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x

Thus, option A) is true.

The solution to the system of equations be:

$x = 4, y = 5$

Step-by-step explanation:

It is important to remember that when we solve the system of equations, the first step we need to do is to solve one of the equations for one of the variables.

Given the system of equations

$x - y = -1$
