Solve the inequality for x. –4x + 6 < 50 A) x > –11 B) x > –14 C) x < –11 D) x < –14

Natali [406]

Answer:

x > -11

Step-by-step explanation:

Step 1: Subtract 6 from both sides

-4x + 6 - 6 < 50 - 6

-4x < 44

Step 2: Divide both sides by -4

-4x / -4 < 44 / -4

If you divide by a negative number, you flip the sign.

x > -11

Answer: x > -11

Answer:

Answer is given below with explanations. 

Step-by-step explanation:

$given \: \: l = 5x - y \: and \: \: b = x + 4y \\ area \: of \: rectangle \:= l \times b \: sq.units \\ = (5x - y)(x + 4y) \\ = 5 {x}^{2} + 20xy - xy - 4 {y}^{2} \\ = 5 {x}^{2} + 19xy - 4 {y}^{2} \\ perimeter \: of \: rectangle \\ = 2(l + b) \\ = 2(5x - y + x + 4y) \\ = 2(6x + 3y) \\ = 12x + 6y$
