Answer:
2 (3 y - 4) <- Complete answer, but since you only have those choices it's
6 y - 8
Step-by-step explanation:
Simplify the following:
8 y - 2 (y + 4)
Hint: | Distribute -2 over y + 4.
-2 (y + 4) = -2 y - 8:
8 y + -2 y - 8
Hint: | Group like terms in 8 y - 2 y - 8.
Grouping like terms, 8 y - 2 y - 8 = (8 y - 2 y) - 8:
(8 y - 2 y) - 8
Hint: | Combine like terms in 8 y - 2 y.
8 y - 2 y = 6 y:
6 y - 8
Hint: | Factor out the greatest common divisor of the coefficients of 6 y - 8.
Factor 2 out of 6 y - 8:

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that the value of a house is $655,000 in cash, but when selling it on installments, you are charged 25.5% of its price.
Assume the price when selling on installments be $x. Then, we can write new price as -
[x] = 655000 + {25.5% of 655000}
[x] = 655000 + {25.5/100 x 655000}
[x] = 655000 + {25.5 x 6550}
[x] = 655000 + 167025
[x] = $822025
Therefore, the price when selling on installments be $822025.

Which transformation is shown by the coordinates below? L (-1, 9) M (-8, 8) N (-3, 5) L '(- 9, -1) M' (- 8, -8) N '(- 5, -3) A. Reflection over the x-axis / B. Translation 8 units left and 8 units down / C. Rotation 90 degrees clockwise / D. Rotation 270 degrees clockwise
Answer:
D. Rotation 270 degrees clockwise.
Step-by-step explanation:
The transformation used in the coordinates below was a rotation 270 degrees clockwise, whose definition is:
[tex](x', y') = (r\cdot \cos (\theta - 270^{\circ}), r\cdot \sin (\theta -270^{\circ}))[/tex]
Please note that clockwise rotation is represented by the minus sign.
Where [tex]r[/tex] is the norm of original point, defined as:
[tex]r =\sqrt{x^{2}+y^{2}}[/tex], [tex]\forall \,x,y\in \mathbb{R}[/tex]
And [tex]\theta[/tex] is the direction of the point centered at origin and with respect to +x semiaxis, measured in sexagesimal degrees:
[tex]\theta = \tan^{-1} \frac{y}{x}[/tex]
Now we proceed to prove the statement:
[tex]L (x, y) = (-1, 9) \longrightarrow L'(x,y)[/tex]
Norm
[tex]r = \sqrt{(-1)^{2}+9^{2}}[/tex]
[tex]r = \sqrt{82}[/tex]
Direction
The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:
[tex]\theta = \tan^{-1}\left(\frac{9}{-1} \right)[/tex]
[tex]\theta = 96.340^{\circ}[/tex]
Rotation
[tex]L'(x,y) = (\sqrt{82}\cdot \cos (96.340^{\circ}-270^{\circ}),\sqrt{82}\cdot \sin (96.340^{\circ}-270^{\circ}))[/tex]
[tex]L'(x,y) = (-9, -1)[/tex]
[tex]M(x,y) = (-8,8) \longrightarrow M'(x,y)[/tex]
Norm
[tex]r = \sqrt{(-8)^{2}+8^{2}}[/tex]
[tex]r = \sqrt{128}[/tex]
Direction
The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:
[tex]\theta = \tan^{-1}\left(\frac{8}{-8} \right)[/tex]
[tex]\theta = 135^{\circ}[/tex]
Rotation
[tex]M'(x,y) = (\sqrt{128}\cdot \cos (135^{\circ}-270^{\circ}),\sqrt{128}\cdot \sin (135^{\circ}-270^{\circ}))[/tex]
[tex]M'(x,y) = (-8, -8)[/tex]
[tex]N(x,y) = (-3,5)\longrightarrow N'(x,y)[/tex]
Norm
[tex]r = \sqrt{(-3)^{2}+5^{2}}[/tex]
[tex]r =\sqrt{34}[/tex]
Direction
The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:
[tex]\theta = \tan^{-1}\left(\frac{5}{-3} \right)[/tex]
[tex]\theta = 120.964^{\circ}[/tex]
Rotation
[tex]N'(x,y) = (\sqrt{34}\cdot \cos (120.964^{\circ}-270^{\circ}), \sqrt{34}\cdot \cos (120.964^{\circ}-270^{\circ}))[/tex]
[tex]N'(x,y) = (-5, -3)[/tex]
Hence, the correct answer is D.

a projectile is thrown upwards from an initial height of 1584 feet so that it's distance above the ground after t seconds is modeled by the given function.
h(t)=-16t^2+480t+1584.
what is the maximum height it will reach?
Answer:
5184 ftStep-by-step explanation:
Given
A quadratic function
h(t)= -16t^2+480t+1584.Its maximum is its vertex
Vertex formula for ax^2 + bx + c is
x = -b/2aApplying this to our function
t = -480/2(-16) = 15Maximum height is reached after 15 seconds and is
h(15) = -16*15^2 + 480*15 + 1584 = 5184 ftLine perpendicular to y = -2x - 7 when it passes the points (-2,-3)
Answer:
The line is y = 1/2x - 2
Step-by-step explanation:
The required line will have a slope of -1/-2 = 1/2.
Using the point slope form of a line:
y - (-3) = 1/2(x - (-2))
y + 3 = 1/2x + 1
y = 1/2x - 2.

Answer:k=−a3−a2b−36a−36b+217/a2+ab
Step-by-step explanation:Step 1: Flip the equation.
a3+a2b+a2k+abk+36a+36b=217
Step 2: Add -a^3 to both sides.
a3+a2b+a2k+abk+36a+36b+−a3=217+−a3
a2b+a2k+abk+36a+36b=−a3+217
Step 3: Add -a^2b to both sides.
a2b+a2k+abk+36a+36b+−a2b=−a3+217+−a2b
a2k+abk+36a+36b=−a3−a2b+217
Step 4: Add -36a to both sides.
a2k+abk+36a+36b+−36a=−a3−a2b+217+−36a
a2k+abk+36b=−a3−a2b−36a+217
Step 5: Add -36b to both sides.
a2k+abk+36b+−36b=−a3−a2b−36a+217+−36b
a2k+abk=−a3−a2b−36a−36b+217
Step 6: Factor out variable k.
k(a2+ab)=−a3−a2b−36a−36b+217
Step 7: Divide both sides by a^2+ab.
k(a2+ab)
a2+ab
=
−a3−a2b−36a−36b+217
a2+ab
k=

Functions can be represented by tables and equations
The function represented by the table is f(x) = x + 1
From the table, we have the following ordered pairs
(x,y) = (-1,0) (0,1) (1,2) and (2,3)
Notice that the difference between the x and y values is 1.
So, we have:
y - x = 1
Add 1 to both sides
y = x + 1
Express as a function
f(x) = x + 1
Hence, the function represented by the table is f(x) = x + 1

Three friends entered a race around a track. Edward takes 6 minutes to run one lap. Bernie takes 3 minutes to run one lap and it takes Freddie 5 minutes to run one lap. If all three friends begin the race at the same time, how many minutes will it take for all three friends to be at the starting point again?
Answer:
It will take 30 minutes
Step-by-step explanation:
Here, we want to calculate the time it will take for the three friends to be at the starting point again
What we do here is to note the time it will take for each of the three friends to run a lap
That will be 6 , 3 and 5
What we now need to know the time is to find the lowest common multiple of the three amount of time
The lowest common multiple of 6,3 and 5 is 30
So the amount of time it will take the friends to be at the starting point again is 30 minutes
