Answer 1

Answer:

see explanation

Step-by-step explanation:

Substitute the given values of x into f : x → $\frac{3}{7}$ x + 4

x = - 14 → ($\frac{3}{7}$ × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2

x = 28 → ( $\frac{3}{7}$ × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16

x = $\frac{7}{8}$ → ($\frac{3}{7}$ × $\frac{7}{8}$ ) + 4 = $\frac{3}{8}$ + 4 = $\frac{3}{8}$ + $\frac{32}{8}$ = $\frac{35}{8}$

x = - $\frac{2}{9}$ → ($\frac{3}{7}$ × - $\frac{2}{9}$ ) + 4 = ($\frac{1}{7}$ × - $\frac{2}{3}$) + 4 = - $\frac{2}{21}$ + $\frac{84}{21}$ = $\frac{82}{21}$

Answer 2

Answer:

See below in bold.

Step-by-step explanation:

1. 3/7 * -14 + 4

   = -6 + 4

    = -2.

2. 3/7 * 28 + 4

   = 12 + 4

    = 16.

3 3/7 * 7/8 + 4

   =  3/8 + 4

    =   35/8 or 4 3/8.

4. 3/7 * -2/9 + 4

   = -6/63 + 4

   = -2/21 + 4

    = -82/21 or -3 19/21.
