Answer:
see explanation
Step-by-step explanation:
Given
3 - 2x² + 15x² - 10
Factor the first/second and third/fourth terms )
= x²(3x² - 2) + 5(3x² - 2) ← factor out (3x² - 2) from each term
= (3x² - 2)(x² + 5)
6(w^2 +4w +6)
Cannot factor any farther
Answer:
C. Dividing by 4 is the inverse of multiplying by 4.
Step-by-step explanation:
We have been given 4 options. We are asked to choose the option that represents inverse relationship.
We know that inverse of addition is subtraction and vice versa.
We also know that inverse of multiplication is division and inverse of division is multiplication.
Upon looking at our given choices, we can see that option C is the correct choice because we are multiplying and dividing by same number 4. Upon dividing and multiplying a quantity by 4, we will get the same quantity.
Therefore, dividing by 4 is the inverse of multiplying by 4.
Answer:
The correlation between sales and advertising is positive.
Step-by-step explanation:
For every $35 spent on advertising, sales increase by $1
Is FALSE, since y = 500 + 35 x $35, sales increase more than $1
Even if no money is spent on advertising, the company realizes $35 of sales
Is FALSE, if no money is spent, the sales amount to $ 500 (when X = 0)
The coefficient of correlation between sales and advertising is 0.81
Is FALSE, since R² = 0.9. The coefficient of correlation = R = 0.94, not 0.81
The equation is y=2,700x+70,000
the x represents the number of years the 2,700 represents the numbers of people new each year and the 70,000 represents the number of people started with in the town in 2003.
