A)
–13 < x < –1
B)
–1 < x < –13
C)
–13 < x and x > –1
D)
–13 < x or x < –1
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.

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]
Find the intersections
[tex]x = (-7, -1)\\x = (-13, -7)[/tex]

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:
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

Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x + c
Answer:
[tex]y = (-3)\, x + 10[/tex].
Step-by-step explanation:
The question requires that the equation should be in the slope-intercept form [tex]y = m \, x + c[/tex]. The [tex]m[/tex] and [tex]c[/tex] in this equation are constants. In particular:
[tex]m\![/tex] would represent the slope of this line (also known as the gradient of this line,) whereas[tex]c[/tex] would be the [tex]y[/tex]-intercept of this line.The question states that the slope of this line is [tex](-3)[/tex]. Therefore, [tex]m = -3[/tex]. Thus, the equation for this line should be in the form [tex]y = (-3)\, x + c[/tex].
The value of constant [tex]c[/tex] could be found using the other piece of information: the point [tex](3,\, 1)[/tex] is in this line. In other words, the solution [tex]\text{$x = 3$ and $y = 1$}[/tex] should satisfy the equation [tex]y = (-3)\, x + c[/tex].
Substitute [tex]\text{$x = 3$ and $y = 1$}[/tex] into the equation [tex]y = (-3)\, x + c[/tex] and solve for [tex]c[/tex]:
[tex]1 = (-3) \times 3 + c[/tex].
[tex]1 = -9 + c[/tex].
[tex]c = 10[/tex].
Hence, [tex]y = (-3) \, x + 10[/tex] would be the slope-intercept form of the equation of this line.
A.) all real numbers
B.) y>6
C.)y is greater than or equal to -6
D.)x= √6 or -√6
Answer:
C.) y is greater than or equal to -6
Step-by-step explanation:
The range are all the set of y-values that are plotted on the vertical axis (y-axis).
The range starts from -6 and above. Which is y ≥ -6
Therefore, range of the function is said to be:
C.) y is greater than or equal to -6

A desk is purchased for $277. Calculate it's worth after depreciating for 5 years if it's depreciation rate is 20% per year
Answer: $90.77
Step-by-step explanation:
Just did the test
The desk cost $90.76 after Depreciation rate.
What is Depreciation rate?The depreciation rate is the proportion at which an asset depreciates during its anticipated useful life. It may also be described as the portion of an organization's long-term investment in an asset that the organisation claims as a tax-deductible expense over the course of the asset's useful life.
Given:
A desk is purchased for $277.
In one year the depreciation rate is 20% per year.
So, In one year depreciation amount
= 20% of 277
= $55.4
After 2nd year
= 221.6 - 20% of 221.6
= $177.28
After 3rd year
= 177.28- 20% of 117.28
= $141.824
After 4th year
= $113.4592
After 5th year
= 113.4592 - 20% of 113.4592
= $90.76

3(5x - 6) = 6(2x - 12)
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)

simone buys a painting for 24000 later she sells it for 60000 how much is her percentage profit
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%

Answer:
n = √3
m = √3
Step-by-step explanation:
The triangle is an isosceles right triangle with 2 equal base angles of 45° each.
Thus:
Reference angle = 45°
Hypotenuse = √6
Opposite = m
Adjacent = n
✔️To find m, apply the trigonometric function SOH, we have:
Sin 45 = opp/hyp
Sin 45 = m/√6
√6 × 1/√2 = m (sin 45 = 1/√2)
√6/√2 = m
√(6/2) = m
√3 = m
m = √3
✔️To find n, apply the trigonometric function, CAH:
Cos 45 = adj/hyp
Cos 45 = n/√6
√6 × √2/2 = n (cos 45 = √2/2)
√12/2 = n
√(4*3)/2 = n
(2√3)/2 = n
√3 = n
n = √3
