6. Answer: y = 5x - 11

Step-by-step explanation:

Parallel means "same slope".  y = 5x - 2 is in the form y = mx + b,

so the slope (m) = 5

Next, input the point (x₁, y₁ = 2, -1) and slope (m = 5) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - (-1) = 5(x - 2)

y + 1 = 5x - 10

Step-by-step explanation:

Perpendicular means "opposite reciprocal slope". y = -3x + 7 is in the form y = mx + b, so slope (m) = -3 ⇒ m⊥ = [tex]\frac{1}{3}[/tex]

Next, input the point (x₁, y₁ = 3, 5) and slope (m = [tex]\frac{1}{3}[/tex] ) into the Point-Slope formula:

y - y₁ = m(x - x₁)

[tex]y - 5=\dfrac{1}{3}(x - 3)[/tex]

[tex]y - 5 =\dfrac{1}{3}x - 1[/tex]

   [tex]y=\dfrac{1}{3}x + 4[/tex]

Answer: C

Step-by-step explanation:

  [tex]\dfrac{x+1}{x-5} - \dfrac{x-2}{x+3}[/tex]

= [tex]\dfrac{x+1}{x-5}(\dfrac{x+3}{x+3}) - \dfrac{x-2}{x+3}(\dfrac{x-5}{x-5})[/tex]

= [tex]\dfrac{x^{2}+4x+3}{(x-5)(x+3)} - \dfrac{x^{2}-7x+10}{(x-5)(x+3)}[/tex]

= [tex]\dfrac{x^{2}+4x+3-(x^{2}-7x+10)}{(x-5)(x+3)}[/tex]

= [tex]\dfrac{11x-7}{(x-5)(x+3)}[/tex]

In order to express the equation 5x - y = -17 in slope-intercept form (y = mx + b), we need to solve for y. After rearranging, it turns out the correct equation in slope-intercept form is y = 5x + 17.

To write the equation 5x - y = -17 in slope-intercept form, we first need to solve the equation for y. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope, and b represents the y-intercept.

Let's rearrange the given equation: Start by adding 'y' to both sides to get 5x = y - 17. Add 17 to both sides, you will get y = 5x + 17. So, the correct answer is: y = 5x + 17. This aligns with option c.

Answer:

The function is  1/4x^2  + x - 8

Step-by-step explanation:

In Factor form the function  is

a(x + 8)(x - 4)    where a is a constant to be found.

= a( x^2 + 4x - 32)  Note the coefficient of x is positive because the function has a minimum value.

The line of symmetry is x = (-8+4)/2 = -2.

So the minimum value  will be the  value of f(x) when x = -2, so we have the equation

a(-2+8)(-2-4) = -9

-36a = -9

a = 1/4.

Choice A is a trinomial, but it doesn't have a constant term

Choice D is the only other trinomial. This has a constant term, which is 6. The constant is the term without any variables attached to it.

Answer: Choice D

Answer:  D. [tex]x+7y+6[/tex]

Step-by-step explanation:

We know that a trinomial is a polynomial with three terms.

From all the given options, only option A. [tex]x^3+12x^2+x[/tex] and option D. [tex]x+7y+6[/tex] are trinomials having three terms .

But option A [tex]x^3+12x^2+x[/tex] does not have any constant term .

On the other hand option D. [tex]x+7y+6[/tex] has a constant term of 6.

Therefore, the option D. [tex]x+7y+6[/tex] represents a trinomial with a constant term.

Answer:

Tiffany is 34% closer to the school.

Step-by-step explanation:

Given the statement: Tiffany used to live 15 kilometers away from the school, but after she moved she now lives 9.9 kilometers away.

She lived away from the school = 15 km

as, she moved 9.9 km away.

Now, the distance closer to school from where she lived = 15 -9.9 = 5.1 km

To, find how much percent she is closer to school.

Percent states that a number or ratio expressed as a fraction of 100.

[tex]percent = \frac{5.1}{15} \times 100[/tex] = [tex]\frac{51 \times 100}{150} = \frac{51 \times 10}{15}[/tex]

Simplify:

percent closer to school = 34%

Therefore, she is 34% closer to the school.

Answer:

The object will hit the ground after 10.308 seconds.

Step-by-step explanation:

h(t) = -16t² + 1700

If you graphed this function, the object would be shown hitting the ground when it crosses the x-axis, in other words, when h = 0. So, to find the answer, just set h(t) equal to 0 and solve.

-16t² + 1700 = 0   Plug this into a calculator if you have one.

t = -10.308 and t = 10.308

Since time can't be negative, your answer will be the positive value, 10.308.

The object, described by the equation h(t) = -16t^2 + 1700, will hit the ground after around 10.308 seconds. This is determined by setting h(t) to 0, yielding a valid, positive solution.

The provided equation h(t) = -16t^2 + 1700 describes the height (h) of an object as a function of time (t), taking into account gravitational acceleration. To determine when the object hits the ground, set h(t) to 0 and solve for t:

-16t^2 + 1700 = 0

Solving this equation using the quadratic formula or factoring yields two solutions: t = -10.308 and t = 10.308. However, time cannot be negative in this context, so the only valid solution is t = 10.308.

Consequently, the object will hit the ground after approximately 10.308 seconds. This conclusion is reached by identifying the point where the height function intersects the x-axis, representing ground level. The positive value for t ensures a meaningful interpretation in the temporal context, indicating the time elapsed until the object reaches the ground.

If the line MN is the angle bisector of ΔJMK, then it creates two angles of equal measure. Hence, m∠JMN is half of m∠JMK due to the property of an angle bisector.

In the field of geometry, an angle bisector is a line or ray that divides an angle into two equal angles. This is given by the information provided that MN is an angle bisector of ΔJMK.

By definition, if MN is an angle bisector of ΔJMK, then it creates two angles, ∠JMN and ∠NMK, that are equal in measure. So, we have m∠JMN = m∠NMK. This is the definition of an angle bisector, which is the reason you are looking for.

Given this, if you want to find m∠JMN in terms of ∠JMK, keep in mind that MN bisects ∠JMK, creating the two equal angles we just mentioned. Therefore, m∠JMK = m∠JMN + m∠NMK. Since ∠JMN and ∠NMK are equal, m∠JMK = 2m∠JMN. Hence, m∠JMN = 1/2m∠JMK. This would be a consequence of the angle bisector property.

Answer: 131,400$

Step-by-step explanation:

The sale for first  month is $500.

The sale increases by $10 each month, as modelled by the equation:

a_k=500+(k-1)10

where, k = 1 (first month)

k = 2 (second month)

.... and so on.

we have to calculate the sale for the first 10 years, that means for 10*12 = 120 months (1 year = 12 months)

Total sales = ∑ a_k

∑ a_k = ∑ (500+(k-1)10)

= 500k + ∑ (10k - 10)

= 500k + 10∑k - 10k

= 490k + 10∑k

= 490k + 10 {k*(k+1)/2}

= 490k + 5{k*(k+1)}

= 490k + 5k^2 + 5k

= 5k^2 + 495k

∴∑ a_k = 5k^2 + 495k

For calculating the total sales of 10 years, we will put the value of k = 120 (120th month after the first month)

= 5*(120*120) + 495*120

= 72,000 + 59, 400

= 131,400$

Answer:

Final answer:

The new price of the item is $3 after the 85% reduction from the original price of $20.

Explanation:

To find the new price of the item after an 85% reduction, we start with the original price and calculate 85% of that price to know how much is being subtracted. The original price is $20. Now let's calculate 85% of 20 dollars:

0.85 (85%) × $20 = $17

This means an $17 reduction from the original price. We subtract this from the original price to find the new price:

$20 - $17 = $3

The new price of the item is $3 after a reduction of 85%.

Answer:

x = 7 and y = 2

Step-by-step explanation:

the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non-zero for this value then it is a vertical asymptote

solve x - 7 = 0 ⇒ x = 7 is the asymptote

horizontal asymptotes occur as

[tex]lim( x → ± ∞), f(x) → c ( where c is a constant )

divide terms on numerator/ denominator by x

f(x) = (3/x/x/x -7/x ) + 2

as x → ± ∞, f(x) → 0 / 1 - 0 + 2 = 2

y = 2 is the asymptote

Answer: Vertical asymptote is x = 7

              Horizontal asymptote is y = 2

Step-by-step explanation:

The vertical asymptote is the restriction on the domain (x-value).  Since the denominator cannot be zero  ⇒  x - 7 ≠ 0  ⇒  x ≠ 7  so the vertical asymptote is at x = 7.

The horizontal asymptote (H.A.) is the restriction on the range (y-value). There are three rules that determine the horizontal value which compare the degree of the numerator (n) with the degree of the denominator (m):

In the given problem, n = 0 and m = 1  ⇒  n < m  ⇒  H.A. is y = 0

Since there is a vertical shift of +2 units, the H.A. is y = 0 + 2  ⇒  y = 2

Answer:

[tex]18[/tex] skis and [tex]10[/tex] snowboards were rented.

Step-by-step explanation:

Let the number of skis rented be [tex]x[/tex] and the number of snowboards rented be [tex]y[/tex].

If a total of [tex]28[/tex] people rented on a certain day, then the total number of skis and snowboards rented that particular day is also [tex]28[/tex].

This gives us the equation

[tex]x+y=28...eqn(1)[/tex].

If skis cost $ [tex]16[/tex], then [tex]x[/tex] number of skis cost $ [tex]16x[/tex].

If snowboards cost $ [tex]19[/tex], then [tex]y[/tex] number of snowboards cost $ [tex]19y[/tex].

The total cost will give us another equation,

[tex]16x+19y=478...eqn(2)[/tex]

From equation (1),

[tex]y=28-x...eqn(3)[/tex].

We put equation (3) into equation (2) to get,

[tex]16x+19(28-x)=478[/tex]

We expand the brackets to obtain,

[tex]16x+532-19x=478[/tex]

We group like terms to get,

[tex]16x-19x=478-532[/tex]

This implies that,

[tex]-3x=-54[/tex]

We divide both sides by [tex]-3[/tex] to get,

[tex]x=18[/tex]

We put [tex]x=18[/tex] into equation (3) to get,

[tex]y=28-18[/tex]

[tex]y=10[/tex]

Therefore [tex]18[/tex] skis and [tex]10[/tex] snowboards were rented.

To solve this problem, you can set up a system of equations where one equation represents the total number of skis and snowboards rented, and the other represents the total cost of those rentals. By solving this system, you can determine the number of skis and snowboards rented.

This problem is a classic example of a system of linear equations. Let's denote the number of skis rented as x and the number of snowboards rented as y. From the problem, we know that:

By solving these two equations, we can find the values of x and y which represent the number of skis and snowboards rented respectively.

Final answer:

To convert y = -3/4x - 6 to standard form with integers, multiply by 4 to remove the fraction and then arrange the equation as 3x + 4y = -24.

Explanation:

To write the equation y = -3/4x - 6 in standard form using integers, we need to rearrange the terms so that the x and y terms are on the left side of the equation and the constant is on the right side. Moreover, in standard form, the coefficients should be integers. The standard form is typically expressed as Ax + By = C.

Starting with the given equation:

y = -3/4x - 6

Multiply each term by 4 to remove the fraction:

4y = -3x - 24

Now, we need to move the x term to the left side of the equation:

3x + 4y = -24

This is the standard form of the equation, and all the coefficients are integers.

Answer:

Pretty sure the answer is 18-30i

Step-by-step explanation:

-30i - 18 x (-1)

-30i +18

The expression -6i(5+3i) simplifies to 18 - 30i in standard form of a complex number.

The problem asks us to simplify the expression -6i(5+3i). To simplify this, we multiply the complex number (-6i) with the complex number in the parenthesis. This results in (-6i * 5) + (-6i * 3i) which transforms into -30i - 18i^2. Since i^2 is -1, we can simplify further to -30i + 18. So the simplified form in standard form is 18 - 30i.
