Suppose the linear regression line \( y=3.009 x \) - 77.131 predicts a pizza parlor's profits based on the number of pizzas sold. If \( x \) represents the number of pizzas sold, and \( y \) represents the pizza partor's profits in dollars, about how much can the plizza parlor expect in profits if it sells 275 pizzas? A. \( \$ 750 \) B. \( \$ 900 \) C. \( \$ 825 \) D. \( \$ 675 \)

a) \( \log _{2} x=1-x \);

e) \( (3 x+2) \cdot\left(x^{3}-2 x^{2}+1\right)= \)

a) \( \log _{2} x=1-x \);

5) \( 4(2-x)=x+3 \)
