Which ordered pair is not a solution of the equation y = 2x – 1

Answer: H

Explanation:

The format is (x,y) ; (4,9) Therefore, you plug in 4 for x then 9 for y. Which will give you “9=2(4)-1” and then simplify, which will give you.. “9=8-1 AKA 9=7” which is not accurate. Therefore that is NOT a solution to the equation...

STEP-BY-STEP:

y = 2x - 1

9 = 2(4) - 1

9 = 8 - 1

9 = 7

^^^^ NOT TRUE

So, therefore the answer IS H (4,9) because it’s asking what is NOT a solution.

Answer:

The first amount is larger by 25%  or .25a

Step-by-step explanation:

Lets increase a by 50%

The increase is .5a

So the new value is a + .5a = 1.5a

Now we will decrease the new value by 50%

decrease = .5 (1.5a) = .75a

The new value of a is 1.5a - .75a = .75a

a > .75a

a - .75a = .25a

a is bigger than .75a by .25a
