Medals 0 The first question is: Solve.
−s3 ≥6


s ≥ –2
s ≤ –2
s ≥ –18
s ≤ –18 This one?

Question 2:
Identify the solution set of the inequality, using the given replacement set.
x < –4; {–10, –4.3, –4, –3.9, 2, 6.5}

{–10, –4.3, –4}
{–4, –3.9, 2}
{–10, –4.3} This one?
{–3.9, 2}

Question 3:
Find the inequality whose solution is the following:

-10-5 -40
y + 3 ≥ –1
y + 3 > –1
y + 3 ≤ –1
y + 3 < –1 This one?
Question 4:
Find the inequality whose solution is the following:
-10-50510-7
y + 5 –2
y + 5 ≥ –2
y + 5

Answer 2

2 is So, you have an inequality: x<−4

You also have a replacement set: {–10,–4.3,–4,–3.9,2,6.5}

The solution set is just all of the numbers in the replacement set that make the inequality true. -10 < -4, that one works. -4.3 < -4, that one works. -4 < -4, nope, that doesn't work. -3.9, 2, 6.5 all fail as well. So the solution set is simply {−10,−4.3}

im sorry i havent done this in so long

Answer 22

It's okay. Do you know anyone who can?

Answer 23

Question 1:
\[−s3 ≥6 \]
divide both sides by -3, and since the divisor is negative, we have to flip the operator sign:
\[s \le \frac{ 6 }{ -3 }\]
and we'll get:
\[s \le -2\]
which happens to be B

Answer 24

For Question 2, you're right @Miss.Rose

Answer 25

For Question 3, we have to suppose an example equation first:
\[-10, -5, -40\]
\[y + 3 = -1\]
\[y = -4\]
now we compare each given value's relation to y = -4
\[-10 < -4\]
\[-5 < -4\]
\[-40 < -4\]
we see that all three values are less than -y, so we can conclude:
\[y + 3 < -1\]
which happens to be D as you suggested, but keep in mind that C is also a possibility.
