1. a=b+3(4-c) If b equals 5 and c equals 2, what is the value of a?

2. y=3(x+5)(x-2) Which of the following formulas is equivalent to this one?

a. y=3x2+9x-30

b y=x2=3x-10

c. y=3x2+3x-10

d. y=3x2+3x-30

3. y=x+5 Which of the following choices represents the same relationship as demonstrated in this equation?

a y/5 x/10

10 15

15 20

20 25

b. Y is equivalent to the sum of a constant c and x, where c equals 5

c y=(x+20)/4

d. [table]

Please show steps to solving these problems.

Thanks In Advance
