Answer:

x= 0, y = -1

Step-by-step explanation:

5x + 16y = -16

-9x – 8y = 8. , multiply both sides of this equation by 2

5x + 16y = -16

-18x – 16y = 16 , add both equations so the y will eliminate

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

-13x = 0, divide both sides by -13

x = 0

5·0 + 16y = -16, substitute x= 0 in the first equation and solve for y

16y = -16 , divide both sides by 16

y = -1

The solution of the system of equation is the point ( x= 0, y = -1)

Write a compound inequality that the graph could represent.

Dmitry_Shevchenko [17]

A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use $\leq$ or $\geq$ to represent that situation, whereas a white dot indicates that the number is not contained within the inequality.

Our graph is telling us that $x$ is greater or equal than -1, and also $x$ is less than 3. So our inequality will be:

$-1 \leq x \leq 3$
