Answer:

d. 60

Step-by-step explanation:

According to Gay Lussac's Law

P1/T1=P2/T2  where

P1= Pressure at the start, T1 = initial Temperature

, P2= Final Pressure, T2 =Final Temperature

T1=P1*T2/P2= 7*420/49=60

What’s this question
yKpoI14uk [10]
<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>

If the y would be equal to 0, everything would then just depend if you add or subtract the x:

y-x=-3\\\\y+x=3\\\\y= 0\\x=3\\\\then:\\\\0-3=3\\and\\0+3=3

Now the first answer could be correct for:

y-x=-3\\because\ if\\\\y=-3 \ and \ x=0 \ then\\-3-0=-3

However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)

Find the equation of the line with slope = 6 and passing through (-9,-58). Write your equation in the form y = mx+ b
stira [4]

Answer:

<u>y=6x-4</u>

Step-by-step explanation:

<u>What we know</u>

  • the slope is 6
  • our point is (-9,-58)

-9 is x and -58 is y so we have to find the y-intercept y=mx+b is also the formula for this

-58=6(-9)+b

-58=-54+b

-58=54+b        - we changed -54 to a positive 54

54-58=-4

y=6x-4
