Question

Please helppppppppppp​

Answer 1

See below in bold.

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.

Answer 2

see explanation

Explanation:

Substitute the given values of x into f : x →
`(3)/(7)` x + 4

x = - 14 → (
`(3)/(7)` × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2

x = 28 → (
`(3)/(7)` × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16

x =
`(7)/(8)` → (
`(3)/(7)` ×
`(7)/(8)` ) + 4 =
`(3)/(8)` + 4 =
`(3)/(8)` +
`(32)/(8)` =
`(35)/(8)`

x = -
`(2)/(9)` → (
`(3)/(7)` × -
`(2)/(9)` ) + 4 = (
`(1)/(7)` × -
`(2)/(3)`) + 4 = -
`(2)/(21)` +
`(84)/(21)` =
`(82)/(21)`
