Write the set of real numbers from -10 through 10 in interval notation.

alexdok [17]

Answer:

$Interval: [-10.10]$

Step-by-step explanation:

Given

Set: -10 to 10

Required

Write as interval notation

We start by writing the given parameter as an inequality

$Inequality: -10 \leq x \leq 10$

The direct representation of $\leq$ and $\geq$ in interval representation of sets is $[$ and $]$ , which shows that the beginning and end of the interval are inclusive;

So, the above inequality in interval notation is:

$Interval: [-10.10]$

Help #4-8 please thank you

Olin [163]

Answer:

#4: 130/60, simplified is 13/6 (divide numerator and denominator by 10)

#5: 110/130, simplified is 11/13 (divide numerator and denominator by 10)

#6: 5/12

#7: 4/12, simplified is 1/3 (divide numerator and denominator by 4)

#8: 12/4, simplified is 3, or 3/1 (divide numerator and denominator by 4)

Step-by-step explanation:

#4: Part 1 is 60 miles, and the whole trip is 60 + 20 + 50 = 130 miles

So while #1 was 60 over 130 for "60 to 130", now we'll put the 130 on top of the 60 for "130 to 60" as a spoken ratio

#5: I think they mean add part 1 to part 3, then compare to the whole.

so 60 + 50 = 110, and your answer is 110/130

Punch: 3 pints Hawaiian punch, 4 pints of orange juice, 5 pints of ginger ale is the recipe. When you pour that all together, you have 3 + 4 + 5 pints of mixed punch as a total, or 12 pints.

#6: 5 pints of ginger ale to 12 pints of punch: 5/12

#7: 4 pints of orange juice to 12 pints of punch: 4/12

#8 12 pints of the whole drink to 4 pints of orange juice: 12/4

Solve each two-step inequality and graph the solution set on a number line -17 < 3-5x

lawyer [7]

Answer:

$x < 4$

Step-by-step explanation:

Given the following question:

$-17 < 3-5x$

In order to find the answer, we will solve the inequality as if it is a regular two-step equation and then we will plot the answer on the number line.

$-17 < 3-5x$
$-17 < 3-5x=3-5x > -17$
$3-5x > -17$
$3-3=0$
$-17--3=-20$
$5x=-20$
$\frac{5x}{5}=x$
$20\div5=-4$
$x < 4$

<u>When plotting inequalities on the number line keep a few things in mind:
</u>
. 4 is greater than x, so the line will go towards the opposite direction of four
. < is a greater sign, it's not a greater or equal to sign (≤) which means it will be an open dot.

Hope this helps.
