Here they hav given the same value as 273.15 just to mislead you.
To find a temperature in Kevin's for a given temperature,you hav to add 273.15 to the given C° temperature.
So in this case write the equation
K = C° + 273.15
So to find the C° take the 273.15 to the other side of the eual sign.
Then the answer is
C°= K - 273.15
Neither.
Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.
Rewriting the 2nd equation to solve for y,
You get:
Y=1/5x + 1/2
The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.
Hope that helps!
The y is the same for both equations. Equate them
-x - 5 = 2x + 4 Add x to both sides
- 5 = 3x + 4 Subtract 4 from both sides.
- 9 = 3x Divide by 3
x = -9 / 3
x = - 3
y = - x - 5
y = -(-3) - 5
y = - 2
So that point is where the two equations meet.

y = -x - 5; y = 2x + 4 Note the semi colon in the middle.
To the moderator: This is my own work. I'm using Wolfram to get the answer.
Im pretty sure it's C because
w/7>3
7×(w/7)>(3)×7
w<21
Trabajando con porcentajes, concluimos que la pérdida es de $4800.
<h3>
¿A cuánto asciende la pérdida?</h3>
Sabemos que la inversión inicial es de $60000, y de esta cantidad, se pierde un 8%.
Entonces la pérdida va a ser el 8% de $60000.
Podemos escribir las relaciones:
$60000 = 100%
x = 8%
Queremos resolver esto para x, tomando el cociente entre esas relaciones y resolviendo para x obtenemos:
x = $60000*(8%/100%) = $60000*0.08 = $4800
Así, concluimos que la pérdida es de $4800.
