The coordinates of the vertices of quadrilateral ABCD are (−6,−1), (−5,2), (−1,−5), and (0,−2). Parker states that quadrilateral ABCD is a parallelogram. Prove or disprove Parker’s statement.
As the length of the sides AD ≠ BC the given quadrilateral ABCD is not a parallelogram.
What approach proves the lines are parallel?To prove that the given lines are parallel we have to determine their slope if the slope if equal then the lines are parallell.
We know that a quadrilateral is a parallelogram when opposite lines are of the same length and opposite lines are parallel to each other.
Given a quadrilateral, ABCD has coordinates A(−6,−1), B(−5,2), C(−1,−5), and D (0,−2).
∴ The quadrilateral ABCD t be a parallelogram length of AB = DC and length of AD = BC.
We know the distance formula is [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
So, lenght of AB = [tex]\sqrt{ (-5+6)^2 + (2 + 1)^2[/tex].
AB = [tex]\sqrt{ 1 + 9}[/tex].
AB = [tex]\sqrt{10}[/tex] units.
Lenght of DC = [tex]\sqrt{(0+1)^2 + (-2+5)^2}[/tex].
DC = [tex]\sqrt{10}[/tex] units.
Now length of AD = [tex]\sqrt{0+6)^2 + (-2+1)^2[/tex].
AD = [tex]\sqrt{ 37}[/tex] units.
Length of BC = [tex]\sqrt{(-1+5)^2 + (-5+2)^2[/tex].
BC = [tex]\sqrt{25}[/tex].
BC = 5 units.
As BC ≠ AD therefore quadrilateral ABCD is not a parallelogram.

How long will it take money to double if it is invested at the following rates?
(A) 6% compounded monthly
(B) 10.2% compounded monthly
(A) years
(Round to two decimal places as needed.)
(B) years
(Round to two decimal places as needed.)
The number of years it would take to double at 6% compounded annually is 11.55 years
The number of years it would take to double at 10.2% compounded annually is 6.8 years
What is the doubling time?When an amount earns at a compound interest, it means that the investment increases at an exponential rate. This means that the rate of growth in a new compounding period would be greater than the rate of growth at the previous compounding period.
When an amount is compounded monthly, it means that both the amount invested and the interest that has already been earned increases in value once a month, twelves times a year.
The formula that can be used to determine the number of years it would take the investment to double is:
Number of years it would take to double = In (FV / PV) / r
Where:
FV = future value PV = present value FV / PV = 2 r = interest rater = 6/12 = 0.5%
r = 10.2 /12 = 0.85%
Number of years it would take to double = In2 / 0.005 = 138.629 months
138.629 months / 12 = 11.55 years
Number of years it would take to double = In2 / 0.0085 = 81.547 months
81.547 months / 12 = 6.8 years

Gail height increased by 24 is 50
Gail height increased by 24 is 50 is g + 24 = 50
Before we begin, note the following:
a increased by b means that we will add a and b, In other words, the expression would be a + b
Now, for our problem:
We have "g" as Gail's height.
The given information is as follows:
i. Gail's height increased by 24 means that we will add g and 24.
ii. Gail's height increased by 24 is 50 means the increased height is equal to 50.
Hence, Based on the above, the expression is: g + 24 = 50

Nate is 2 years younger than Alan and Kai is half Alan's age. The sum of their ages is 63. How old is Kai?
The ages of Alan, Nate and Kai is 26, 24 and 13 years respectively
AlgebraAlan's age = x yearsNate's age = (x - 2) yearsKai's age = 1/2xTotal ages = 63 years63 = x + (x - 2) + 1/2x
63 = x + x - 2 + 1/2x
63 = 2 1/2x - 2
63 + 2 = 2 1/2x
65 = 5/2x
divide both sides by 5/2x = 65 ÷ 5/2
x = 65 × 2/5
= 130/5
x = 26
Recall,
Alan's age = x years
= 26 years
Nate's age = (x - 2) years
= (26 - 2)

The blue fabric costs $2 more per yard than the green fabric. She pays a total of $62. What would be the combined cost of 1 yard of blue fabric and 1 yard of green fabric?
The price of green fabric = $4 and the price of blue fabric is $6.
How to illustrate the information?It should be noted that LaTanya buys 5 yards of blue fabric and 8 yards of green fabric and the blue fabric costs $2 more per yard than the green fabric.
Let the price of the green fabric = x
Price of blue fabric = x + 2
Therefore, the expression will be:
5(x + 2) + 8(x) = 62
5x + 10 + 8x = 62
13x = 62 - 10
13x = 52
Divide
x = 52/13
x = 4
The price of green fabric = $4

The line which is parallel to the given line y = -2x/3 + 1 is 2x+3y=-18, there slopes are equal
How to fine the line that is parallel to the given lineGiven data
line y = -2x/3 + 1
The equation of a line is represented as y = mx + c where m represents the slope. The unique feature of parallel line is that the slopes are equal.
Hence we find the line that has same value of m which is the slope
using the second option: 2x+3y=-18
2x + 3y = -18
3y = -2x - 18
y = -2x/3 - 6

commission on her sales. In July, Christa made 35 successful sales calls and Megan made 29 successful sales calls.
They each had the same sales, in dollars, for July, and they made the same total salary that month. Which equation
can be used to find x, the amount Christa and Megan each had in sales in July?
The equation that shows the amount Christa and Megan each had in sales in July is 630 + 0.03x = 609 + 0.035x
What is an equation?An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.
Let x represent the amount Christa and Megan each had in sales in July. Hence:
For Christa = 18(35) + 0.03x
For Megan = 21(29) + 0.035x
630 + 0.03x = 609 + 0.035x
