Translate the phrase "nine more than two times a number" into an algebraic expression. what is the answer to this

Mathematics
1 answer:
svlad2 [7]3 years ago
5 0

Answer:

<em>The algebraic expression will be:  2x+9 , where x is the number.</em>

Step-by-step explanation:

Suppose, the number is x

Now, "two times the number" means 2 is multiplied with the number. As the number is x, so "two times the number" will be:  2x

Then "9 more than" means 9 is added. So, "9 more than 2x" will be:  2x+9

Thus, the algebraic expression will be:  2x+9

$9 a day for 8 days.

So, for every day that went by they earned $9. In other words the answer is the Amount of Money Earned per day multiplied by the number of days!

So!

$9 * 8days

Or you can also think of it as this: 
9+9+9+9+9+9+9+9

Our answer comes out to be 72!

What is the square root between which two intergers explain ​
Softa [21]

Answer:

I’m pretty sure the square root between two Integers is when you have a non perfect square root for example the square root of 92. Since it is not perfect you have to estimate it and you use a numeric line to do it so in this case the square root of 92 would have to go in between the nearest perfect square roots from both sides which are 81 and 100. In the line you would see it as 9 and 10 and you have to estimate the value which in this case would be about 9.6

Y= x^2 -5 solve for x
dexar [7]

Y= x^2 -5

We need to solve for x, we need to get x alone

Y= x^2 -5

Lets start by removing -5

Add 5 on both sides

y + 5= x^2 -5 + 5

y + 5= x^2

Now to isolate x , we need to remove the square from x

To remove square , take square root on both sides

+-\sqrt{y+5} = \sqrt{x^2}

square and square root will get cancelled

+-\sqrt{y+5} = x

So x = +\sqrt{y+5} and  x = -\sqrt{y+5}

6. Polynomial Division<br> Divide. (3x4 – 3x3 – 6x –10) ÷ (x – 2)
vovangra [49]

Answer:

Quotient = -6

Remainder = -19

Step-by-step explanation:

(3*4 - 3*3 - 6x-10) / (x-2)

= (12 - 9 - 10 - 6x) / (x-2)

= (-6x -7) / (x-2)

Quotient = -6

Remainder = -19
