Answer:
y= -6x - 15
Step-by-step explanation:
First you need to plug in the x and y coordinates into the equation y = -6x and you should get (-3) = -6(-2). Then you do -6 x -2 which is 12 then subtract 12 from -3 and get -15.

Answer:
x = 31
Step-by-step explanation:
Given that the triangles are congruent, then corresponding angles are congruent, then
∠ D = ∠ A
The sum of the 3 angles in a triangle = 180° , thus
∠ A = 180° - (61 + 57)° = 180° - 118° = 62°
Thus
2x = 62 ( divide both sides by 2 )
x = 31

In the diagram shown below PS is perpendicular to RT and the two lines intercept at W. Ray WQ is drawn. Which of the following statements about angle pairs in incorrect?
Answer:
D. angle SWT and angle QWT are complementary
Step-by-step explanation:
The angles formed at W when the two lines, PS and RT, which are perpendicular to each other intercept at W are right angles.
Thus, let's analyse each given statements to see which is true or not true about the angle pairs formed:
Statement 1: "angle PWQ and angle QWT are complementary".
m<PWT = 90°.
m<PWQ + m<QWT = m<PWT (angle addition postulate)
m<PWQ + m<QWT = 90° (definition of complementary angles)
Therefore, statement 1 is CORRECT.
Statement 2: "angle PWR and angle TWP are supplementary".
m<PWR = 90°
m<TWP = 90°
m<PWR + m<TWP = 180° (definition of supplementary angles)
Therefore, statement 2 is CORRECT.
Statement 3: "angle RWQ and angle TWQ are supplementary".
<RWQ and <TWQ are angles on a straight line and are a linear pair.
m<RWQ + m<TWQ = 180° (definition of supplementary angles)
Therefore, statement 3 is CORRECT.
Statement 4: "angle SWT and angle QWT are complementary".
m<SWT = 90°
Therefore, m<SWT + m<QWT ≠ 90°
The sum of both angles does not give 90°. Therefore, statement 4 is INCORRECT.

An exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles, using this property we get, the value of k is: k = 10.
Here, we know that, an exterior angle is equal to the sum of the two opposite inside angles.
The picture shows an exterior angle of 115 degrees.
It's two opposite inside angles are the two equations.
This means:
(4k +5) + (6k+10) = 115
Combine like terms:
10k + 15 = 115
Subtract 15 from both sides:
10k = 100
Divide both sides by 10:
k = 100/10
k = 10
Hence, The value of k is: k = 10.

You need a loan of $110 comma 000 to buy a home. Calculate your monthly payments and total closing costs for each choice below. Briefly discuss how you would decide between the two choices. Choice 1: 15-year fixed rate at 6% with closing costs of $1200 and no points. Choice 2: 15-year fixed rate at 5.5% with closing costs of $1200 and 4 points.
What is the monthly payment for choice 1? $
(Do not round until the final answer. Then round to the nearest cent as needed.)
Answer:
Monthly payment for choice 1 is $6,600
Step-by-step explanation:
We will use following formula in order to calculate the monthly payment of choice 1
Value of Loan = Monthly payment x ( 1 - ( 1 + Interest rate )^-numbers of payments / interest rate
Where
Value of Loan = $110,000
Interest rate = 6%
Numbers of Payment = 15 years x 12 payments / year = 180 payments
Placing values in the formula
$110,000 = Monthly payment x ( 1 - ( 1 + 6% )^-180 ) / 6%
$110,000 = Monthly payment x 16.6662
Monthly Payment = $110,000 / 16.6662
Monthly Payment = $6,600.18
Monthly Payment = $6,600 (Rounded to whole number)

The area of the circle is 144π m2
What is the diameter of the circle?
Answer:
Step-by-step explanation:
Remember that
Area of Circle = [tex]\pi r^2[/tex]
[tex]\pi = pi \\r = radius[/tex]
They told us that for this circle, the area is [tex]144\pi m^2[/tex]
If you put it back into the formula for area of a circle we get:
Area of Circle = [tex]\pi r^2[/tex]
[tex]144\pi = \pi r^2[/tex]
Divide both sides by [tex]\pi[/tex].
144 = [tex]r^2[/tex]
Now we want to solve for r (r = radius).
You need to square root each side
[tex]\sqrt{144} = \sqrt{r^2}[/tex]
[tex]12 = r[/tex]
So now we know the radius, [tex]r = 12[/tex] metres
Also remember that
Diameter = [tex]2r[/tex]
So,
Diameter = 2 times 12 = 24 metres
The required diameter of the given circle is 24 meters.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
The given area of the circle is 144π m²
And we know that,
Area = πr²
substitute the value of the area in the above expression,
144π = πr²
r² = 144
r = √144
r = 12 meters
Since,
Diameter = 2 × radius
Diameter = 2 × 12 = 24 meter
Thus, the required diameter of the given circle is 24 meters.

An ice skating show earned 15,385 in one night. Tickets for the show cost $25 for adults and $15 for children. The number of adults who attendee the shw was 41 more than the number of children who attended the show. How many adults and children attended the show?
Answer:
Number of adults that attended the show = 400
Number of children that attended the show = 359
Total people who attended the show = 759
Step-by-step explanation:
Total earned = 15,385
Adults = $25
Children = $15
Let
Adults = A
Children = C
The number of adults who attendee the show was 41 more than the number of children who attended the show
A = C + 41
25A + 15C = 15,385
Substitute
A = C + 41
25(C+41) + 15C = 15,385
25C + 1,025 + 15C = 15,385
40C + 1,025 = 15,385
40C = 15,385 - 1,025
40C = 14,360
Divide both sides by 40
C = 14,360 / 40
= 359
C = 359
Substitute C = 359 into
A = C + 41
A = 359 + 41
= 400
A = 400
Number of adults that attended the show = 400
Number of children that attended the show = 359
Total people who attended the show = 759

Step-by-step explanation:
if a polynomial is divided by x-5, the quotient is 2x^2 +8x-9 and the remainder is 3 what is the original polynomial?
Answer:
[tex]P(x)=2x^3-2x^2-49x+48[/tex]
Step-by-step explanation:
Let the original polynomial be [tex]P(x)[/tex].
We know that when it is divided by [tex](x-5)[/tex], the quotient is [tex]2x^2+8x-9[/tex] and we get a remainder of 3.
Therefore, this means that:
[tex]\frac{P(x)}{x-5}=2x^2+8x-9+\frac{3}{x-5}[/tex]
Remember what it means when we have a remainder. Say we have 13 divided by 3. Our quotient will be 4 R1, or 4 1 over 3. We put the remainder over the divisor. This is the same thing for polynomials.
So, to find our original polynomial, multiply both sides by [tex](x-5)[/tex]:
[tex](x-5)\frac{P(x)}{x-5}=(x-5)(2x^2+8x-9+\frac{3}{x-5})[/tex]
The left side will cancel. Distribute the right:
[tex]P(x)=2x^2(x-5)+8x(x-5)-9(x-5)+\frac{3}{(x-5)}(x-5)[/tex]
Distribute:
[tex]P(x)=(2x^3-10x^2)+(8x^2-40x)+(-9x+45)+(3)[/tex]
Combine like terms:
[tex]P(x)=(2x^3)+(-10x^2+8x^2)+(-40x-9x)+(45+3)[/tex]
Evaluate:
[tex]P(x)=2x^3-2x^2-49x+48[/tex]

In 2005, MusicMart sold 14,550 CDs. In 2010, they sold 12,000 CDs. What is the rate of change in the number of CDs sold?
A) -2550 per yr B) -510 per yr C) -425 D) -2400 per yr
Answer:
B) -510 per yr
Step-by-step explanation:
2005 = 14,550 CDs sold
2010 = 12,000 CDs sold
Difference in years = 2010 - 2005
= 5 years
Difference in CDs sold = 12,000 - 14,550
= - 4,550
Rate of change in the number of CDs sold = change in the number of CDs / change in years
= -4,550 / 5
= -510 per year
The correct answer is B) -510 per yr

Cars are made in a factory for 24 hours every day.
In the factory a car is made every 209 seconds.
Work out an estimate for the number of cars made in the factory in one year.
Answer:
6,591,024,000
Step-by-step explanation:
Minutes in 24 hours=1,440
number of seconds in 24 hours=60*1440
=86,400..
number of cars made in each second=209
number of cars made in 86,400 seconds= 18,057,600
24 hours =one day
1 year =365 days
cars made in one year =365*18,057,600
=6,591,024,000
therefore, the number of cars made in one year =
6,591,024,000
The number of cars made in the factory in one year where cars are made for 24 hours every day is 150891.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done W in a day can is,
[tex]W=\dfrac{1}{n}[/tex]
In a factory, cars are made, where Cars are made for 24 hours every day. As, there is total 60 seconds in one minute and 60 minutes in one hour. Thus, the number of second in 24 hours is,
