What is the solution to the inequality d/7+ 4 ≤ 0?

(–∞, –28)
(–∞, –28]
(28, ∞)
[28, ∞)

The solution to the inequality is  (–∞, –28]

Option B is correct.        

Step-by-step explanation:

Given the inequality

We have to find the solution to the inequality.

Subtracting 4 both sides

Multiply by 7 both sides

Hence, the solution of d is the values less than equals to -28 i.e  

 (–∞, –28]

Option B is correct.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
