What is the difference of the two polynomials? (7y2 6xy) â€"" (â€""2xy 3) 7y2 4xy â€"" 3 7y2 8xy â€"" 3 7y2 4xy 3 7y2 8xy 3.
Answers
Answer:
There is no difference
Step-by-step explanation:
The difference between the polynomials is 7y² + 8xy - 3
Polynomials are functions that have a degree of power greater than two.
According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)
f(x, y) = (7y^2 + 6xy) - (-2xy + 3)
f(x, y) = 7y² + 6xy + 2xy - 3
f(x, y) = 7y² + 8xy - 3
Hence the difference between the polynomials is 7y² + 8xy - 3

What is the price of rice per gram?
dollars per gram of rice
Answers
Answer:
Price of rice per gram = $ 0.006 per gram or 0.6 cents per gram .
Step-by-step explanation:
Given: David wants to make 10 servings, where each serving has 75 grams of rice.
Total quantity of rice required = 10 x 75 = 750 grams
Overall, David spends 4.50 dollars on rice.
i.e. cost of 750 grams of rice = 4.50 dollars
Price of rice per gram =(cost of 750 grams of rice ) ÷ 750
= (4.50 dollars ) ÷ 750
= $ 0.006 per gram.
Price of rice per gram = $ 0.006 per gram.

Which mathematical statement represents “17 more than a number is 26”?
17 greater-than 26
n + 17 = 26
17 less-than 26
26 + n = 17
Answers
Answer:
n + 17 = 26
Step-by-step explanation:
Let's replace the sentence with mathematical terms:
17 more than a number is 26
More than means addition. The answer will also be a sum.
17 + a number is 26
Since the number is not specified, it will be represented by a variable. In this instance, the variable is n.
17 + n is 26
The equal sign will replace the word "is".
17 + n = 26
Now, we can use the associative property of addition.
17 + n = 26 into n + 17 = 26
Which mathematical statement represents “17 more than a number is 26”?
Answer:
n + 17 = 26
Step-by-step explanation:
17 more than a number means that you are adding 17 to a number (n) to equal 26.
If you take 17 away from each side you get n = 9
9 + 17 = 26 is a true statement so the equation is correct.

If a new car is valued at $26,000 and 10 years later it is valued at $7000, then what is the average rate of change
of its value during those 10 years?
Answers
Answer:
The change in value is 19,000 altogether and 1900/year
Step-by-step explanation:
Change in value:
initial value - final value
= $26,000 - $7000
= $19,000
Change in value/year:
change in value/time
= $19,000/10
= $1900/year

[tex]x+y=-9\\ x+2y=-25\\what is value of x[/tex]
Answers
x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7
