Inequalities are expression not separated by an equal sign. None of the inequality is correct since there is absence of equal sign.
<h3>Graph of inequalities</h3>
Inequalities are expression not separated by an equal sign. According to the question, we ned the inequality's graph that will have a dashed boundary line.
An inequality that will have solid boundary line must include only the less than or equal to sign < or greater than or equal to > sign.
From the option given, none of the inequality is correct since there is absence of equal sign.

HI HI from the UK,
Step-by-step explanation:
Answer:
386
Step-by-step explanation:
If you subtract the initial fee of 12 from 70 you get 68 you just divide that by .15 meaning you can plant no more that 386 trees.
Answer:Given that the graph shows tha the functión at x = 0 is below the y-axis, the constant term of the function has to be negative. This leaves us two possibilities:
y = 8x^2 + 2x - 5 and y = 2x^2 + 8x - 5
To try to discard one of them, let us use the vertex, which is at x = -2.
With y = 8x^2 + 2x - 5, you get y = 8(-2)^2 + 2(-2) - 5 = 32 - 4 - 5 = 23 , which is not the y-coordinate of the vertex of the curve of the graph.
Test the other equation, y = 2x^2 + 8x - 5 = 2(-2)^2 + 8(-2) - 5 = 8 - 16 - 5 = -13, which is exactly the y-coordinate of the function graphed.

Answer:
-5,-11
8,14
Step-by-step explanation:
Let 's say r the commun difference
1)
1,1+r,1+2r,1+3r=-17
1+3r=-17
3r=-18
r=-6
Sequence is 1,-5,-11,-17
2)
2,2+r,2+2r,2+3r=20
2+3r=20
3r=18
r=6
Sequence is 2,8,14,20
