You use a sine function to model the percentage of the moon's face that is lit by the sun every night. at full moon, all of
the moon's face is lit (100%). at new moon, none of the moon's face is lit (0%)
the output of your function expresses percentages as decimals. for example, 5% = 0.05.
what is the amplitude of your sine function? a)0.1 b)0.5 c)1.0 d)2.0

Fractions can be added and subtracted only if they're fractions. a. like b. proper c. improper d. unlike

What is the value of x in the following equation? -3x-2=2x+8

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
