Answer:
k = 5
Step-by-step explanation:
-2k = k - 7 - 8
Combine like terms
-2k = k - 15
add 15 to both sides
-2k + 15 = k
Add 2k to both sides
15 = 3k
Divide both sides by 3
k=5

Answer:
[tex] \boxed{\sf d. \ \frac{a}{b} = \frac{10}{7}} [/tex]
Step-by-step explanation:
[tex] \sf \implies \dfrac{a - b}{b} = \dfrac{3}{7} \\ \\ \sf \implies \frac{a}{b} - \frac{b}{b} = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 + 1 = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + \frac{7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{3 + 7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{10}{7} [/tex]

A coin is tossed twice. Determine whether the events of getting tails twice are independent or dependent. Then identify the indicated probability.
Answer:
Hi there!
They are independent. The first toss does not change the outcome of the sides. If you have a fair coin it's 50-50 weight.
1/2 × 1/2 = 1/4
There's a 25% chance of getting tails twice

factorize the expression: 9x^4 + 12x^2y + 4y^2
Answer:
(3x² + 2y)²
Step-by-step explanation:
Given
9[tex]x^{4}[/tex] + 12x²y + 4y² ← a perfect square
9[tex]x^{4}[/tex] = (3x²)² and 4y² = (2y)²
of the form
9[tex]x^{4}[/tex] + 12x²y + 4y² = (3x² + 2y)(3x² + 2y) = (3x² + 2y)²
The point (1,-4) is on the line given by which equation below?
A. y=-2x
B. y=-4x
C. Y=x-4
D. y=4x
Answer:
B. y = -4xStep-by-step explanation:
(1, -4) ⇒ x = 1, y = -4
A. x=1 ⇒ y = -2•1 = -2 ≠ -4
B. x=1 ⇒ y = -4•1 = -4
C. x=1 ⇒ y = 1 - 4 = -3 ≠ -4
D. x=1 ⇒ y = 4•1 = 4 ≠ -4

the length of a rectangle is 6 inches more than twice it's width.If the perimeter of a rectangle is 60,find it's dimensions.
Answer:
length = 22 incheswidth = 8 inchesStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 60 in
The statement
the length of a rectangle is 6 inches more than twice it's width is written as
l = 6 + 2w
Substitute the statement into the above formula
That's
60 = 2( 6 + 2w) + 2w
60 = 12 + 4w + 2w
6w = 60 - 12
6w = 48
Divide both sides by 6
w = 8
Substitute w = 6 into l = 6 + 2w
That's
l = 6 + 2(8)
l = 6 + 16
l = 22
The dimensions are
length = 22 inches
width = 8 inches

What is meant by “offensive is not illegal”?
Answer:
It depends on the country and it depends on the act itself.
In US, there is such thing as freedom of speech (with some common-sense limitations), however same will get a person thrown in jail and sentenced to death in a country where any speaking out is deemed as illegal.
So, are you planning on offending someone by calling them stupid or are you planning on violating someone's religious beliefs by desecrating their house of worship?
Are you planning on showing an adult film to a bunch of kids or are you going to tell kindergarteners that Santa is not real?
Upset feelings are not exact damages to be shown in court to demand compensation, however a damage to one's reputation or causing a financial loss (or a loss of life if that offense goes too far) would land that person in legal trouble.

Find the limit............
Answer: [tex]-\frac{9}{x^2}[/tex]
====================================================
Work Shown:
[tex]\displaystyle \lim_{\Delta x \to 0^{+}} \frac{\frac{9}{x+\Delta x} - \frac{9}{x}}{\Delta x}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{\frac{9x}{x(x+\Delta x)} - \frac{9(x+\Delta x)}{x(x+\Delta x)}}{\Delta x}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{\frac{9x-9(x+\Delta x)}{x(x+\Delta x)}}{\Delta x}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{9x-9x-9\Delta x}{x\Delta x(x+\Delta x)}\\\\\\[/tex]
[tex]\displaystyle \lim_{\Delta x \to 0^{+}} \frac{-9\Delta x}{x\Delta x(x+\Delta x)}\\\\\\\displaystyle \lim_{\Delta x \to 0^{+}} \frac{-9}{x(x+\Delta x)}\\\\\\\displaystyle \frac{-9}{x(x+0)}\\\\\\\displaystyle -\frac{9}{x^2}\\\\\\[/tex]
The trick here is to first simplify the expression so that the [tex]\Delta x[/tex] term in the very lower denominator cancels out. This is to avoid dividing by zero. Once this division by zero error is avoided, we can replace the delta x term with 0 and evaluate the limit as [tex]\Delta x[/tex] approaches 0 from the right or positive direction.
