Which values are in the solution set of the compound inequality? Select two options
zhannawk [14.2K]

The values are in the solution set of the compound inequality are (-6, -3), (3, 8).

<h3>What is inequality?</h3>

Inequality is the phenomenon of unequal distribution of resources and opportunities among the given function.

To find the number that are solutions to the compound inequalities, the value of x is

First inequality:

4(x +3) ≤0

4x +12 ≤0

4x ≤-12

x ≤-3

The value of x lies in the interval = (-∞ , -3]

Second inequality:

x +1 >3

x>2

The value of x lies in the interval = (2 , ∞)

So, the interval solution is (-∞ , -3] U (2 , ∞)

Thus, the values are in the solution set of the compound inequality are (-6, -3), (3, 8).

Kristen gets home from work at 5:34 p.m. Kristen's dinner is ready at 5:51 p.m.
bazaltina [42]

Answer:

1,020 seconds

Step-by-step explanation:

we know that

To find out how many seconds after Kristen gets home is her dinner ready, subtract the time Kristen gets home from the time Kristen's dinner is ready

so

5:51 p.m-5:34 p.m=17 min

Remember that

1\ min=60\ sec

Convert minutes to seconds

17\ min=17(60)=1,020\ sec

LUCKY_DIMON [66]

Hello!

To find our answer, we first convert 1/2 into fourths. We multiply it by 2/2, giving us 2/4.

2/4+1/4=3/4

Therefore, our answer is \boxed {\frac{3}{4}}.
