Answer:

Yes it is, because...

Step-by-step explanation:

This is an inequality, so you can treat it as an algebraic expression.

The first step is to multiple both sides by 2, to get rid of the 2 on the left side.
Your equation will now look like this:
y >= 2y - 22

The next step is to get all the y variables to one side, now that its a lot more simplified. Subtract 2y from both sides to get:
-y >= -22

Finally, cancel out the negative on both sides of the equation to get the y as a positive y, all by itself. This will get you:
y <= 22

REMINDER: when you divide by a negative number, such as in this case dividing by -1 on both sides, the inequality sign will flip!

y = 18 works because it is less than 22. (:

Answer:

John needs $3\frac{3}{4}$ yards of blue ribbon.

Step-by-step explanation:

We have been given that Jon uses a piece of red ribbon witch is 3/4th yard long. Jon also needs blue ribbon that is 5 times as long as the ribbon. We are asked to find the amount of blue ribbon that John needs.

To find the amount of blue ribbon that John needs, we will multiply amount of red ribbon by 5 as shown below:

$\text{Amount of blue ribbon}=5\times \frac{3}{4}$

$\text{Amount of blue ribbon}=\frac{5\times 3}{4}$

$\text{Amount of blue ribbon}=\frac{15}{4}$

$\text{Amount of blue ribbon}=3\frac{3}{4}$

Therefore, John needs $3\frac{3}{4}$ yards of blue ribbon.

Answer:

4x^2+8x-5

Step-by-step explanation:

You work backwards to get (2x-1) which gets you the root 1/2 and (2x+5) which gets you the root -5/2 after this you foil what you have so (2x-1) times (2x+5). You do 2x times 2x which gives you 4x^2 2x times 5 which gives you 10x -1 times 2x which gives -2x and lastly -1 times 5 which gives you -5 now you combine like terms and get your final answer of 4x^2+8x-5
