C)
–13 < x and x > –1
D)
–13 < x or x < –1
Answers
Answer:
A) - 13 < x < - 1
Step-by-step explanation:
1) Rewrite the inequality without the absolute value.
[tex] - 6 < x + 7 < 6[/tex]
2) Subtract 7 from the whole equation.
[tex] - 6 - 7 < x < 6 - 7[/tex]
3) Simplify.
[tex] - 13 < x < - 1[/tex]
Therefor, the answer is the first option.
Answer:
A) –13 < x < –1
Step-by-step explanation:
|x + 7| < 6
Separate into possible cases
[tex]x + 7 < 6 \\x +7 \geq 0[/tex]
Solve the inequalities
[tex]x < - 1, x \geq -7\\x > -13, x < -7[/tex]

3(5x - 6) = 6(2x - 12)
Answers
Answer:
x = -18
Step-by-step explanation:
Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72
15x - 18 = 12x - 72
Add 18 to both sides: 15x = 12x - 54
Subtract 12x from both sides: 3x = -54
Divide both sides by 3: x = -18
Answer:
x= 17.666666...
Step-by-step explanation:
3(5x - 6) = 6(2x - 12)
(3 times 5x , 3 times -6) (6 times 2x, 6 times - 12)
15x-18 = 12x -72 (multiply insides)
-12x -12x (remove 12x from right side)
3x-19 = -72 (product)
+19 = +19 (add 19 left side to remove it)
3x = 53 (product)
x = [tex]\frac{53}{3}[/tex] (divide)
x= 17.666666... (answer)
x = 17.67 (if simplify)

Mel took out a loan of $40,000 at 14 percent on March 16, 2015 which will be due on January 9, 2016. Using exact interest the amount of Mel's interest cost is:
Answers
Answer:
the interest cost is $4,679.45
Step-by-step explanation:
The computation of the interest cost is shown below:
= Loan amount × rate of interest × given no of days ÷ total no of days in a year
= $40,000 × 14% × 305 days ÷ 365 days
= $4,679.45
hence, the interest cost is $4,679.45
I REALLY Need help ASAP
Answers
Answer:
A
Step-by-step explanation:
In order to multiply a whole number by a fraction, you can write the whole number in fraction form. -12 can also be written as [tex]\frac{-12}{1}[/tex].
Now you can write out [tex]\frac{-12}{1}[/tex] × [tex]\frac{20}{21}[/tex]
Multiply the numerators by each other and the denominators by each other to create one fraction.
-12 × 20 = -240 and 1 × 21 = 21
[tex]\frac{-12}{1}[/tex] × [tex]\frac{20}{12}[/tex] = [tex]\frac{-240}{21}[/tex] and now you can simplify the fraction by finding the greatest common factor of the denominator and numerator. -240 and 21 have the greatest common factor of 3. Divide each side by 3 and get the fraction -80/7

Find the amplitude and vertical shift?
Please write down the parent function and the function creating the graph.
Answers
Answer:
The amplitude = 2b, and the verticle shift = 2, which means it has been shifted down 2 units.
Step-by-step explanation:
The highest point is when y = 0 and the lowest point is when y = -4. The vertical distance between the peak and valley is 4 units, which cuts in half to 2. This is the amplitude. It's the vertical distance from the center to either the peak or valley.

simone buys a painting for 24000 later she sells it for 60000 how much is her percentage profit
Answers
Answer:
percentage profit = 150%
Step-by-step explanation:
percentage profit = sp - cp/cp * 100
sp is the selling price = 60000
cp is the cost price = 24000
percentage profit = 60000-24000/24000 * 100
percentage profit = 36000/24000 * 100
percentage profit = 36000/240
percentage profit = 150%
