Hi there!
[tex]\large\boxed{y = -x + 7}[/tex]
To begin, we must use the slope formula to calculate the slope of the line:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the coordinates:
[tex]m = \frac{-5-(-2)}{12-9}[/tex]
Simplify:
[tex]m = \frac{-3}{3} =-1[/tex]
Recall that the equation for a line in point-slope form is:
y - y1 = m(x - x1)
Plug in coordinates into the equation along with the slope:
y - (-2) = -1(x - 9)
Simplify:
y + 2 = -x + 9
y = -x + 7

DEFG is an isosceles trapezoid with bases FE and
GD. DE = 5x -2, and FG = 4x + 2. Find FG.
Answer:
FG is 18 units
Step-by-step explanation:
if the trapezoid is isosceles then DE = GF so we can create this equation:
4x + 2 = 5x - 2
4x = 5x - 4
-x = -4
x = 4
FG = 4(4)+2 which is 18

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The number of pairs of pants = 2 pairs
The number of pairs of t-shirts = 8 pairs
The number of pairs of shoes = 2 pairs
And , the total number of outcomes A = 2 x 8 x 2
On simplifying the equation , we get
The different outfits does Joseph can choose A = 32 outfits
Hence , the equation is A = 32 outfits

DF = 10
scale factor of ΔDEF to ΔXYX is 1:3
Step-by-step explanation:
DF corresponds to XZ and DE corresponds to XY so we can set up a proportion:
6x+6/30 = 8/24
simplify 8/24 to be 1/3
6x+6/30 = 1/3
cross-multiply:
3(6x+6) = 30
18x + 18 = 30
18x = 12
x = 12/18 or 2/3
When a biological researcher arrived on Wombat Island, there were about 1000 wombats on the island. Their population grew quickly. Estimated Wombat Population Year 1 2 3 4 5 Wombats 1000 2000 4000 8000 16,000 The researcher decided that the population growth followed a geometric sequence. He wrote the explicit formula an = 1000(2)n – 1 to model the growth, and used this formula to predict the populations for years 6, 10, and 50.
Answer:
Yes
Step-by-step explanation: The explicit formula used: An = 1000(2)n - 1 is the correct formula. This is modeled as exponential growth with a common ratio of 2; which is correct based on the data given in the table.
The predicted population for year 50 is approximately [tex]1.1259[/tex] x [tex]10^18[/tex] wombats.
To predict the populations for years 6, 10, and 50 using the given explicit formula an = [tex]1000(2)^n[/tex] – 1, we can substitute the respective values of n and calculate the population.
For year 6 (n = 6):
a6 = [tex]1000(2)^6[/tex] – 1
a6 = 1000(64) – 1
a6 = 64,000 – 1
a6 ≈ 63,999
The predicted population for year 6 is approximately 63,999 wombats.
For year 10 (n = 10):
a10 = [tex]1000(2)^ 10[/tex]
a10 = 1000(1,024) – 1
a10 = 1,024,000 – 1
a10 = 1,023,999
The predicted population for year 10 is 1,023,999 wombats.
For year 50 (n = 50):
a50 = [tex]1000(2)^50[/tex] – 1
a50 = 1000(1.1259 x 10¹⁵ ) – 1
a50 = 1.1259 x 10¹⁸ – 1
a50 ≈ 1.1259 x 10¹⁸
The predicted population for year 50 is approximately 1.1259 x 10^18 wombats.

A rectangle is formed by placing two identical squares side by side. The area of the rectangle is 162 cm2
Answer:
a) The area of each square is 81 square centimeters.
b) The side length of the square is 9 centimeters.
c) The perimeter of the rectangle is 54 centimeters.
Step-by-step explanation:
Statement is incomplete. After some web research we conclude that the complete statement is the following:
A rectangle is formed by placing two identical squares side by side. The area of the rectangle is 162 square centimeters. Find:
a) The area of each square.
b) The side length of each square.
c) The perimeter of the rectangle.
a) The area of the each square is half the area of the rectangle. Hence, the area of each square is 81 square centimeters.
b) The area formula for squares ([tex]A[/tex]), in square centimeters, is:
[tex]A = l^{2}[/tex] (1)
Where [tex]l[/tex] is the side length of the square, in centimeters.
If we know that [tex]A = 81\,cm^{2}[/tex], then the side length of the square is:
[tex]l = \sqrt{A}[/tex]
[tex]l = \sqrt{81\,cm^{2}}[/tex]
[tex]l = 9\,cm[/tex]
The side length of the square is 9 centimeters.
c) The perimeter formula of the rectangle ([tex]p[/tex]), in centimeters, is presented below:
[tex]p = 6\cdot l[/tex]
[tex]p = 6\cdot (9\,cm)[/tex]
[tex]p = 54\,cm[/tex]
The perimeter of the rectangle is 54 centimeters.

5) A qué % anual se prestó un capital de 1700 soles que en 1 año y 3 meses ha producido 255 soles de interés?
Answer:
12%
Step-by-step explanation:
Interés simple = Principal × Tasa × Tiempo
Tasa = Interés simple / Principal × Tiempo
Principal = 1700 soles
Tiempo = 1 año y 3 meses
12 meses = 1 año
3 meses = 3/12 = 1/4 = 0.25
Tiempo = 1.25 años
Tasa = 255 /1700 × 1.25
= 0.12
= 0.12 × 100

For the first four days of a five day vacation, the mean temperature was 80 degrees. What must the temperature be on the fifth day in order for the mean temperature to be 82 degrees?
Answer:
The 5th day must be 90
Step-by-step explanation:
The first 4 days averaged out to 80
You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.
80*4 = 320
Now you need to add another day into the mix. Call it x
320 + x
Now there are 5 days, not 4, and the new total is 82.
(320 + x) / 5 = 82 Multiply both sides by 5
5*(320 + x) / 5 = 82 *5
320 + x = 410 Subtract 320
-320 -320
x = 90

A company that makes robotic vacuums claims their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. What are the appropriate hypotheses?
H0: μ = 2 versus Ha: μ < 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ > 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model
H0: μ ≠ 2 versus Ha: μ = 2, where μ = the true mean run time for all vacuums of this model
Answer:
The answer is C. H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model

find the coordinates of the intersection of the diagonals of parallelogram PQRS with vertical P(-5,5) Q(2,5) , R(4,-3) and S(-3,-3)
Given:
The vertices of parallelogram PQRS are P(-5,5) Q(2,5) , R(4,-3) and S(-3,-3).
To find:
The intersection of the diagonals of parallelogram PQRS.
Solution:
We know that the diagonals of a parallelogram bisect each other.
In parallelogram PQRS, PR and QS are the diagonals of the parallelogram.
It means the intersection of PR and QS is the midpoint of PR and QS.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Midpoint of diagonal PR is:
[tex]Midpoint=\left(\dfrac{(-5)+4}{2},\dfrac{5+(-3)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-1}{2},\dfrac{2}{2}\right)[/tex]
[tex]Midpoint=\left(-0.5,1\right)[/tex]
Therefore, the coordinates of the intersection of the diagonals of parallelogram PQRS are (-0.5,1).

Answer:
R'=(-3,6)
Q'=(-3,-3)
S'=(7,6)
T'=(7,-3)
Answer:
see explanation
Step-by-step explanation:
A translation of 7 units right means adding 7 to the x- coordinate. The y- coordinate remains unchanged, then
Q (- 10, - 3 ) → Q' (- 10 + 7, - 3 ) → Q' (- 3, - 3 )
R (- 10, 6 ) → R' (- 10 + 7, 6 ) → R' (- 3, 6 )
S (0, 6 ) → S' (0 + 7, 6 ) → S' (7, 6 )
T (0, - 3 ) → T' (0 + 7, - 3 ) → T' (7, - 3 )
