Answer:
$750.
Step-by-step explanation:
Let x represent the number of pizzas sold, and y represent the pizza parlor's profits in dollars.
We have been given the linear regression line
, which predicts a pizza parlor's profits based on the number of pizzas sold.
To find the profit of pizza parlor when it sells 275 pizzas, we will substitute x=275 in our given equation.



Therefore, the pizza parlor will make a profit of $750, if it sells 275 pizzas.
Answer: l=12.05

No, they are not equivalent. The first term, -4 1/2 equals 4 whole units and one half unit. All negative. So it’s like you have someone 4 and 1/2 dollars.
The second term, (-4)1/2 means multiplying -4 times 1/2. Doing the multiplication for this gives you -4/2. Solving the division here is -2. It’s taking away 1/2 dollar 4 times.
I hope this helped. Happy to answer any questions you have.
Answer:
x²(9x– 11)(9x + 11)
Step-by-step explanation:
81x⁴ – 121x²
The expression can be factorised as follow:
81x⁴ – 121x²
x² is common to both term. Thus:
81x⁴ – 121x² = x²(81x² – 121)
Recall:
81 = 9²
121 = 11²
Therefore,
x²(81x² – 121) = x²(9²x² – 11²)
= x²[(9x)² – 11²]
Difference of two squares
x²(9x– 11)(9x + 11)
Therefore,
81x⁴ – 121x² = x²(9x– 11)(9x + 11)
