X=7
add 3 to both sides.
hope this helps!
3: m= 2, -3
4: x= -1, 5/2
5: x= -1, -3
6: x= 5/2, -4
Answer:
C: -2<x≤7
Step-by-step explanation:
- -2<x, as there is an open circle on -2
- x≤7 as there is a closed circle on 7
- Put them together, -2<x≤7
Answer:
100 psia
Step-by-step explanation:
Applying,
Pressure law,
P/T = P'/T'................. Equation 1
Where P = initial pressure, P' = Final pressure, T = initial temperature, P' = Final temperature.
make P' the subject of the equation
P' = PT'/T............ Equation 2
From the question,
Given: P = 50 psia, T = 300°R = (300×5/9)K = 166.66 K, T' = 600°R = (600×5/9)K = 333.33 K
Substitute these values into equation 2
P' = (50×333.33)/166.66
P' ≈ 100 psia
P ≈ 100 psia
