Answer:

B. -7 is less than or equal to x, which is less than 12

Step-by-step explanation:

-7x -50 </= -1

add 50 to both sides

-7x <= 49

divide both sides by -7. When you divide and inequality by a negative number, the direction of the inequality changes.

x >/= -7

---------------------------------

-6x + 70 > -2

subtract 70 from both sides

-6x > -72

divide both sides by -6, flipping the inequality sign

x < 12

------------------------------

Since the problem says *and*, we can say x is equal than or greater to -7 and less than 12

-7 </= x < 12

please let me know if you have questions, or if the signs don't come through clearly

Answer:

X= 43/3

Step-by-step explanation:

-1/4 x 5 = 3/4x - 12

-5/4=3/4x -12

-5=3x - 48

-3x-5 = -48

-3x = -48 + 5

-3x= -43

-3 x= -43

X= 43/3

The dashed line is because the sign is greater than to be a solid line it has to be equal to or greater than and to the shading means any point on there works for the equation easiest way to test where you should shade is by plugging into the equation the point (0,0)
