Is this right? someone please help! i’ll give brainliest :)

you're right

Step-by-step explanation:

2 + 5x ≥ 52

5x ≥ 50

x ≥ 10

7 - x > -2

-x > -9

x < 9

Yes

The only difference between simplifying equations and inequalities is that if you ever divide both sides by a negative, flip the sign.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.
