Answer:
Correct option is C
Step-by-step explanation:
First, find the equation of the boundary line. This line passes through the points (0,-3) and (-2,1). Then it has equation
In the attached diagram this boundary line is solid, then the sign of the inequality should be with "or equal to" notion (≤ or ≥). Thus, options A and B are false.
The line divides the coordinate plane into two parts and you have to determine which part to choose. The origin does not lie in the shaded region, then its coordinates cannot satisfy the inequality. Check options C and D.
- origin does not satisfy (option C is correct);
- origin satisfies (option D is false).
Answer:
Step-by-step explanation:
Given
Three and one-half yards of fabric i.e. 
yards
and five and one-half yards of fabric is 
yards
Difference between five and one-half yards and Three and one-half yards is
=2 yards which is positive
Thus it clear that 
Answer:
y>23.8
Step-by-step explanation:
48-8y<24.2-7y
-8y+7y<24.2-48
-y<-23.8
y>23.8
Answer: Z = 0.9y - 20
_______
4
Step-by-step explanation: First, add (-20)/3 to both sides. Then, divide both sides by 4/3.
Solve for x:
-59 = 7 x
-59 = 7 x is equivalent to 7 x = -59:
7 x = -59
Divide both sides of 7 x = -59 by 7:
(7 x)/7 = (-59)/7
7/7 = 1:
Answer: x = (-59)/7
