Find the equation of a line parallel to y=2x-4 that contains the points (5,1)

Alex73 [517]

The correct answer is
y=2x-9

Since the lines are parallel, they will gave the same slope (in this case it’s 2)

Our equation will be
y=mx+b

We know the slope is 2, and they’ve given us x and y coordinates. Plugging it in to the slope equation we get

1=2(5)+b

1=10+b

Subtract 10 from both sides and you get

-9=b

Putting it together our new parallel line will be

y = 2x - 9

Answer:

x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27°F or x(-∞,-27]

Step-by-step explanation:

The melting point of the substance is - 32.78°C, then the melting point in °F is given by

$C = \frac{5}{9} (F - 32)$

⇒ $F - 32 = \frac{9}{5}C$

⇒ $F = 32 + \frac{9}{5} (-32.78)$

⇒ F = - 27.004°F

Again, the boiling point of the substance is 349.68°C, hence, the boiling point in °F is

$F = 32 + \frac{9}{5} (349.68)$

⇒ F = 661.424°F

Therefore, the range of temperature in °F for which the substance will not be in liquid state will be x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27.004°F or x(-∞,-27.004], where x is the temperature of the substance in °F. (Answer)
