Find all real number x such that
6x-21≥3 or 14x+11≤-7

Answers

Answer 1

Answer: $6x-21 \geq 3\n \n 6x \geq 3+21\n \n 6x \geq 24\n \n x \geq (24)/(6)\n \n \boxed{x \geq 4}$

$14x+11 \leq -7\n \n 14x \leq -7-11\n \n 14x \leq -18\n \n x \leq (19)/(14)\n \n x \leq (9)/(7)$

Organize the following polynomial expressions from least to greatest based on their degree:I x + 2xyz
II 3x + y + z
III 2x3y + y2x - 3x + 4
IV 9x3yz

A II, III, I, IV

B III, I, IV, II

C I, II, IV, III

D II, I, III, IV

Answers

The degree of a polynomial is equal to the highest sum of the variables among the terms. In I, degree is equal to 3, II is equal to 1, II is equal to 4, and IV is equal to 5. Hence, the order from least to greatest then, the order is II, I, III and IV. Answer is A>

Answer: 2134

Step-by-step explanation:

Solve for y

4y
— - 7 = -3
5

Answers

4y/5 - 7 = -35

Add 7 to both sides:

4y/5 = -28

Multiply 5 to both sides:

4y = -140

Divivde 4 to both sides:

y = -35
