Answer:

  c.  f(x) = (x + 4)(x - 1)

Step-by-step explanation:

Since you're familiar with the product of two binomials:

  (x +a)(x +b) = x² + (a+b)x + ab

you know that the constants in the binomial factors must ...

  • have a product of -4
  • have a sum of +3

__

All of the choices except B have binomial constants that have a product of -4.

In order, the sums of the remaining choices are ...

  A: 1-4 = -3

  C: 4-1 = 3 . . . . this is the correct choice

  D: -2+2 = 0

Sindrei [870]

Solve for y:

3x = 7y + 21

~Subtract 7y to both sides

3x - 7y = 21

~Subtract 3x to both sides

-7y = 21 - 3x

~Divide -7 to both sides

y = -3 + 3/7x

~Change order

y = 3/7x - 3

Best of Luck!

Please answer what the answer for ? Is.
vitfil [10]

Answer:

5/8

Step-by-step explanation:

A.   2/3 × 4/5 × m = 1/3               B.      4/5 × 2/3 × m = 1/3

      8/15 × m = 1/3                                 8/ 15 × m  = 1/3                                    

                 m = 1/3 ÷ 8/15                                 m = 1/3 ÷ 8/15

                  m = 1/3 ×15/8                                 m = 1/3  × 15/8

                  m = 5/8                                          m = 5/8        

C.  2/3 × 4/5 = 1/3 ÷ m        

            8/15 =  1/3 ×  1/m

            8/15 = 1/3m                   cross multiply  

           (3m) × (8) = 15

                24m = 15

                     m = 15/24

                     m=  5/8
