Use the rules for exponents to rewrite the expression and then evaluate the new expression. (-2)2(-2)3
A. -64

Provide an appropriate response.Arrange the quadratic equation in standard form: 8 = 4x2 - x
A. 4x2 = x + 8 B. 4x2 - x = 8 C. -4x2 + x + 8 = 0 D. 4x2 - x - 8 = 0
Provide an appropriate response.If the total profit (in dollars) from the sale of x radios is P(x) = 50x - 0.05x2 - 700 + 5 ln(x), use Newton's method to approximate the break-even points for profit. (Note: There are 2 break-even points; one is between 10 and 50, and the other is between 900 and 1000.)

Use elimination to solve each system of equations, if possible. Identify the system as consistent or inconsistent. If the system is consistent, state whether the equations are dependent or independent. -6x - 4y = -422x + 2y = 14
A. (7, 1); consistent and independent B. (7, 0); consistent and independent C. (6, 1); consistent and independent D. infinitely many solutions and dependent
