1. Choose the linear inequality that describes the graph. The gray area represents the shaded region.

A. y > –3x + 5

B. y > –5x – 3

C. y > –5x + 3

D. y < –5x + 3

D. y < –5x + 3

Step-by-step explanation:

A. 1st picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y > − 3 x + 5

B. 2nd picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y > − 5 x − 3

C. 3rd picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y > − 5 x + 3

D. 4th picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y < − 5 x + 3

b. astronomers

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
