Answer:
A
Step-by-step explanation:
The equation will be in the form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line
m = 
= - 2
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - 2x + 5 or
y = 5 - 2x → A
1 1/5 - 1/3
6/5-1/3
18/15-5/15
13/15 is your answer.
It would be C because it’s asking you to multiple 3/4 by 3/4 sense there is a 2 exponent. And in order to multiply fractions you multiply across the top and bottom and then simplify. Sense c is already simplified that would be your answer. 3 x 3
4x4 9/16 or c
Answer:
2x-12
Step-by-step explanation:
First you distribute the -2 to the x and +3
this will make you expression be:
4x-6-2x-6
you then do -6+-6
this will make your expression be:
4x-12-2x
After you get this you have to combine like terms. the like terms in the expression are the two with x being you variable. 4x and -2x.
Once you have combined like terms your solution should be:
2x-12
Answer:
R ≈ 8.31
Step-by-step explanation:
Filling in the given values ...
... pV = nRT
... 2·4.155 = 1·R·1
... 8.31 = R
