Zandra makes a conjecture that the product of two odd integers is always an odd integer. Which choice is the best proof of her conjecture?
Answer:
Let (2n + 1) be an odd number..... D/last option
Step-by-step explanation:
Zandra makes a conjecture that the product of two odd integers is always an odd integer. And the conjecture is the last option.
What are integers?Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Knowing that 2n is an even integer,
and that it would become odd if we add 1,
the product of two odd integers, 2n+1, is:
Now,
(2n+1) (2m+1)
= (2n+1) x (2m+1)
=4mn + 2n + 2m + 1
=2 (2m + m + n)+1
=2p+1
And 2p+1 is the representation of odd integers.
Therefore, the last option is the best proof of her conjecture.

3. Rotate triangle EFGH 90°. What are the coordinates
of triangle 'J'K'L'?
14. Point P has the coordinates (-2,-4). Point P is dilated with a center at the origin and
a scale factor of 3 to create Point P'.
What are the coordinates of Point P'?
Answer:
Step-by-step explanation:
The answer is b (1,-1)
If a point P is dilated about the origin, coordinates of the image point will be P'(-6, -12).
Rule of the transformation (Dilation):If a point P(x, y) is dilated by a scale factor 'k' about the origin, image point P' will be given by,
P(x, y) → P'(kx, ky)
Given in the question,
Coordinates of point P → (-2, -4)Point P is dilated by a scale factor '3' about the origin to form the image point P'.After the dilation of point P, coordinates of the image point P' will be,
P(-2, -4) → P'(-2×3, -4×3)
→ P'(-6, -12)
Therefore, after dilation of point P about the origin, coordinates of the image point will be P'(-6, -12).

Answer:
160 in ^2
Step-by-step explanation:
First we need to find the area of each shape and add them together
1. Triangles:
The formula for a triangle is (base x height)/2, so we can replace them as (5 * 4)/2 * 2( Because there are two triangles), so therefore the two triangles will add up to 20 inches
2. The Rectangles
The Big Rectangle:
The big rectangle is just l x w or 5 * 20 which is 100
The small rectangle:
To find the width of the small rectangle you have to do 20 - (5 + 5) because we are not including the triangles. 20 - (5 + 5) = 10, so that would be 10 * 4 = 40.
3.Add them together
20 + 100 + 40 = 160 inches ^2

Arisia puts $500.00 into a savings account with an annual simple interest rate of 4.5%. If the interest stayed the same, how much interest would arisia's account earn after 15years?
Answer:
$112.5Step-by-step explanation:
Step one:
given data
principal= $500
rate= 4.5= 0.045
time t= 5years
Step two:
the expression for the simple interest is given as
A=P(1+rt)
the interest SI= final amount (A)- Principal(P)
Substituting we have
A=500(1+0.045*5)
A=500(1+0.225)
A=500(1.225)
A=612.5
the interest is 612.5-500
=$112.5

what is the equation for of the line that passes through the point (2,-4) and has a slope of -2
Answer:
y = -2x
Step-by-step explanation:
The equation of the line is y = -2x. Use the form y = mx + b and substitution to find your answer.
The problem already gave you the slope, and m represents the slope.
y = -2x + b
The problem also gave you one point. Substitute the x and y values of that point into the equation.
Point: (2, -4)
-4 = -4 + b
b = 0
Using basic algebra, we found that there is no b value. b equals 0. So all we have to write is y = -2x.
Answer:
y = - 2x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (2, - 4) into the partial equation
- 4 = - 4 + c ⇒ c = - 4 + 4 = 0
y = - 2x ← equation of line

El kilo de pollo en als últimas semanas se incrementó en un 13% o sea aumento de 3.20
Answer:
El kilo de pollo aumentó de $3.20 a $3.61.
Step-by-step explanation:
Si el kilo de pollo se incremento en un 13% en las últimas semanas, pasando de $3.20 a un valor mayor, para determinar dicho valor se debe realizar el siguiente cálculo:
AUMENTO + VALOR INICIAL = VALOR DEL POLLO CON AUMENTO
(3.20 x 13 / 100) + 3.20 = VALOR DEL POLLO CON AUMENTO
(41.6 / 100) + 3.20 = X
0.41 + 3.20 = X
3.61 = X
Por lo tanto, el kilo de pollo aumentó de $3.20 a $3.61 en las últimas semanas.

Given that, The science club raised $98.75 to buy bird feeders and birdseed to place outside the classroom. Club members bought one bag of bird seed for $2.75. Each bird feeder costs $12.
Since, total cost = $98.
And, Money left after bird seed = 98 - 2.75 = $95.25
Therefore, they bought total bird feeder in $95.25
Let they bought x, bird feeders,
Therefor,
12x = 95.25
x = 7.93
x ≈ 8
Hence, the number of feeder they bought is 8.

Then find the unit rate in hours per mile.
ALSO EXPLAIN
10points
Answer:
1.6 miles per hour
Step-by-step explanation:
Step one:
The unit rate is the number of miles in 1 hour
given
distance= 4 miles
time= 2.5 hours
so if he hike 4 miles in 2.5 hours
then he will hike x mile in 1 hour
cross multiply we have
x=4/2.5
x=1.6 miles per hours
Therefore the unit rate is 1.6 miles per hour
