Which expression is equivalent to : (2n - 3)?
1 answer:
Answer: Choice C)
====================================================
Explanation:
We multiply the outer term 4/9 with each term inside
- (4/9) times (2n) = (4*2n)/9 = (8n)/9 = (8/9)n
- (4/9) times (-3) = (4*(-3))/9 = -12/9 = -4/3
The improper fraction 4/3 converts to the mixed number 1 & 1/3
4/3 = (3+1)/3 = 3/3 + 1/3 = 1 + 1/3 = 1 & 1/3
So overall, we can say
This is equivalent to saying

Answer:
The coordinate of the points on the graph as shown , where ( x ,y ) = ( 3 , 2 )
Step-by-step explanation:
Given as :
The two algebraic equation is
y = 2 x - 4 .......A and y = - x + 5 ........B
The given two algebraic equation can be solved by putting the one variable to the other equation
Now , put the value of y from Eq A into the Eq B
I.e 2 x - 4 = - x + 5
or, 2 x + x = 5 + 4
or, 3 x = 9
∴ x =
I.e x = 3
So The value of x = 3
Again, put the value of x in the equation A
I.e y = 2 x - 4
or, y = 2 × 3 - 4
∴ y = 6 - 4
I.e y = 2
So The value of y = 2
So , The coordinate of points on the graph as ( x , y ) = ( 3 , 2 )
Hence The coordinate of the points on the graph as shown , where ( x ,y ) = ( 3 , 2 ) Answer
