Question

$- 8 > 2 x + 10 + 6 x > - 20$ , Which is the possible range of values of 4x + 5 ?

Options:

A . Any value greater than -4 or less than -10

B . Any value greater than -10 & less than -4

C . Any value greater than

- \frac{9}{4}

or less than

- \frac{15}{4}

D . Any value greater than

- \frac{15}{4}

or less than

- \frac{9}{4}

Answer: Option B
:
B

- 8 > 2 x + 10 + 6 x > - 20

- 8 > 8 x + 10 > - 20

Dividing by 2 on each side

- \frac{8}{2} > \frac{8 x + 10}{2} > - \frac{20}{2}

- 4 > 4 x + 5 > - 10
