Question

Solve the inequality and graph the solution.

−2p + 4.5 ≥ −2.9

A - Open plot between 3 and 4 w/ line pointing positive
B - Solid plot between 3 and 4 w/ line pointing negative
C - Open plot between 3 and 4 w/ line pointing negative
D - Solid plot between 3 and 4 w/ line pointing positive

Answer 1

Option B.

Explanation:

`- 2p + 4.5 \geqslant - 2.9 \\ collect \: like \: terms \\ - 2p \geqslant - 2.9 - 4.5 \\ - 2p \geqslant - 7.4`

Removing the negative sign,

`p \leqslant 3.7`

Answer 2

B

Explanation:

`-2p+4.5 \geq -2.9 \\ \\ -2p \geq -7.4 \\ \\ p \leq 3.7`
