A number squared would be x squared (x^2)
The product of x squared and ten is 10x^2
Then subtract nine
10x^2 - 9
Answer:
Option D
Step-by-step explanation:
We have given that function:
We can see this through graph attached that the coordinate of planes on the left and right moves upward.
By the definition of degree of the polynomial state that highest degree of x is the degree of polynomial i.e. 4 which is even which implies that the degree of the function is even.
The above statement implies that the degree of the function is even, so the ends of the graph continue in the same direction. As the leading coefficient is positive, the left side of the graph continues up the coordinate plane and the right side also continues upward.
therefore, option D is correct
Question:
Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.
Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.
Answer:
Step-by-step explanation:
From the complete question, we have:
<u>Jordyn & Teri</u>
<u></u><u></u>
<u></u><u></u>
<u></u>
<u>Morgan</u>
<u></u><u></u>
Required
Expression for Jordyn and Morgan
Let the total kite by Jordyn and Teri be represented with y
This is calculated as:
This gives:
1 roll is represented with x.
So:
This can be rewritten as:
Answer:
A
Step-by-step explanation:
If you were to multiply the top by 7 then add you would cancel out the x and if you were to multiply the bottom by 6 then when you use the subtraction method you multiply the top by negative and if that were to happen you would do -6x + -6x which would cancel nothing out. But if you just add the two equations nothing would cancel out.
Hope this helped!
1. 40 units___16 workers
20 units___x= 8 workers
(20*16)/40=8
2. 40 units___16 workers
25 units___x= 10 workers
(25*16)/40=10
3. 40 units___16 workers
100 units___x= 40 workers
(100*16)/40=40
