Answer:
A.) 1
Step-by-step explanation:
First change the equation to 2 + ( - 8x ) = -6 so it’s easier to read
Take away 2 from both sides
So now you have -8x = -8
Divide both sides by -8 so you get positive x and 1
x = 1
Answer:
2x+y = 20
Step-by-step explanation:
The equation for a line is y = mx+b where m is the lope and b is the y intercept
y = -2x+b
substitute the point into x and y
8 = -2(6) +b
8 = -12+b
Add 12 to each side
20 =b
y = -2x+20
Add 2x to each side
2x+y = 20
Assuming constant pressure, V/T = constant.
Where T is absolute temperature, and V is volume.
T1 = 60 ° + 273.15 = 333.15 K
V1 = 300 cm^3
T2 = 30°C + 273.15 = 303.15 K
V2 = ?
V1 / T1 = V2 / T2 = > V2 = [V1/T1] * T2
V2 = [300cm^3 / 333.15K] * 303.15K = 272.9 cm^3
Answer: 272.99 cm^3
Answer:
E. all values are answer
Step-by-step explanation:
2x+3 greater than or equal to 7 or 2x+9>11
2(2)+3=7 for this one the number 2 or more could be a answer
2(2)+9=13 for this also number 2 or more could be a answer
so, all of the solutions could be a answer.
