Help!! Solving absolute value inequalities
goblinko [34]

Answer:

48. x \geq -7 or x \leq 31

51. x \leq 13 or x \geq 3

54. x < \frac{5}{2} or x > \frac{-15}{2}

57. x < \frac{18}{7} or x > -4

Step-by-step explanation:

48. | 12 - x | \leq 19

-There are two equations:

Equation 1:

12 - x \leq 19

      or

Equation 2:

12 - x \geq -19

Solving equation 1:

12 - x \leq 19

12- 12 - x \leq 19 - 12

-x \leq 7

\frac{-x}{-1} \leq \frac{7}{-1}

x \geq -7 (Inequality sign changed, because of dividing by a negative number)

-Solving equation 2:

12 - x \geq -19

12 - 12  - x \geq -19 - 12

-x \geq -31

\frac{-x}{-1} \geq \frac{-31}{-1}

x \leq 31 (Inequality sign changed, because of dividing by a negative number)

-Answers:

x \geq -7 or x \leq 31

51. | x - 8 | \leq 5

-There are two equations:

Equation 1:

x - 8 \leq 5

    or

Equation 2:

x - 8 \geq - 5

-Solving equation 1:

x - 8 \leq 5

x - 8 + 8 \leq 5 + 8

x \leq 13

-Solving equation 2:

x - 8 \geq - 5

x - 8 + 8 \geq - 5 + 8

x \geq 3

Answers:

x \leq 13 or x \geq 3

54. | 4x + 10 | < 20

-There are two equations:

Equation 1:

4x + 10 < 20

     or

Equation 2:

4x + 10 > -20

-Solving equation 1:

4x + 10 < 20

4x + 10 - 10 < 20 - 10

4x < 10

\frac{4x}{4} < \frac{10}{4}

x < \frac{5}{2}

-Solving equation 2:

4x + 10 > -20

4x + 10 - 10 > -20 - 10

4x > -30

\frac{4x}{4} > \frac{-30}{4}

x > \frac{-15}{2}

-Answers:

x < \frac{5}{2} or x > \frac{-15}{2}

57. | 7x + 5 | < 23

-There are two equations:

Equation 1:

7x + 5 < 23

     or

Equation 2:

7x + 5 > -23

-Solving equation 1:

7x + 5 < 23

7x + 5 - 5 < 23 - 5

7x < 18

\frac{7x}{7} < \frac{18}{7}

x < \frac{18}{7}

Solving equation 2:

7x + 5 > -23

7x + 5 - 5  > -23 - 5

7x > -28

\frac{7x}{7} > \frac{-28}{7}

x > -4

Answers:

x < \frac{18}{7} or x > -4

And we are finished.

What equation makes the line go through the following points. <br>(11, -3) and (7, 9)​
Brums [2.3K]

Answer:

y = -3x + 30

Step-by-step explanation:

First, find the slope using the slope formula:

m = (y2 - y1) / (x2 - x1)

m = (9 - (-3)) / (7 - 11)

m = -12/4

m = -3

Next, find the y-intercept by substituding one of the two points into what the equation is so far:

y = -3x + b

(7, 9)

9 = -3(7) + b

9 = -21 + b

30 = b

Now you have the full equation:

y = -3x + 30

kevin is starting a saltwater aquarium with 36 fish.He wants to start with 11 times as many damselfish as clown fish.How many of
Alex787 [66]
11 times as many damselfish as clownfish would mean damselfish = 11 times clownfish. Use variable to represent each fish, so variable c will be used to represent clownfish and variable d with be used to represent damselfish. So from as before, d = 11c . Since there is a total of 36 fish, the equation would look to be about d + c = 36. Since we know that d = 11c, you replace the d with 11c. So it will now look like 11c + c = 36. Add like terms , which will be 11c + c to equal 12c. So the new equation is now 12c = 36. To isolate variable c, divide 12 to both sides to get c = 3 . There are 3 clownfish. To find out how many damselfish, replace 3 with c in the equation for d, which is d = 11c. d = 11(3) . d = 33. There are 33 damselfish and 3 clownfish in the tank.

The yield from silver queen was compared to the yield of country gentlemen. Note: Differences were taken by taking Silver Queen
Mumz [18]

Answer:

-0.223 \leq \mu_{sylver} -\mu_{Country} \leq 0.988

We can conclude that the difference between the two means are between -0.223 and 0.988.

And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.

Step-by-step explanation:

For this case we have the following interval for the difference between Silver Queen - Country Gentlemen:

-0.223 \leq \mu_{sylver} -\mu_{Country} \leq 0.988

We can conclude that the difference between the two means are between -0.223 and 0.988.

And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.
