Hope this helps!
p.s. could I get brainliest if possible (I only need one more for the next category or whatever)
Would be the last one (-6,6)
Step by step explanation:
Point P is at (-2,3) and you have to do a translation of (x-4 , y+3)
So the. Just do -2-4 that would give u -6 and then 3+3 which would be 6 so your final answer would be (-6,6)

Al precio de p dólares por unidad, se venden x unidades de cierto artículo al mes en el mercado con p=50-0.5x ¿Cuántas unidades como mínimo se deben vender cada mes con el objetivo de tener ingresos de por lo menos de 1.200 dólares?
Answers
Answer:
Se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.
Step-by-step explanation:
De acuerdo con el enunciado, [tex]x[/tex] es la cantidad mínima de artículos a un precio de [tex]p[/tex]. Además, los ingresos totales deben ser de un mínimo de 1200. En consecuencia, tenemos el siguiente sistema de ecuaciones:
[tex]x \cdot p = 1200[/tex] (1)
[tex]p = 50-0.5\cdot x[/tex] (2)
Aplicando (2) en (1), tenemos la siguiente ecuación polinómica:
[tex]x\cdot (50-0.5\cdot x) = 1200[/tex]
[tex]50\cdot x -0.5\cdot x^{2} = 1200[/tex]
[tex]0.5\cdot x^{2}-50\cdot x +1200 = 0[/tex] (3)
Por la Fórmula de la Cuadrática tenemos las raíces del polinomio:
[tex]x_{1} = 60[/tex], [tex]x_{2} = 40[/tex]
De acuerdo con el resultado anterior, se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

A- Parallelogram PQRS is also a rectangle
B- Parallelogram PQRS is also a rhombus.
C- Parallelogram PQRS is neither a rectangle nor a rhombus.
D- Parallelogram PQRS is both a rectangle and a rhombus, so it is a square.

A rectangle do not have perpendicular diagonals.
Hence, (a) is false
If (a) is false, then (d) is also false
(b) PQRS can a rhombus
The diagonals of a rhombus are not perpendicular.
So (b) is true
No need to check for (c), since only option is true

Step-by-step explanation:
15-14.25/15
original - sale price divided by original = percent change
15-14.25/15 = 0.75/15 = 0.05 = 5%
15-14.25=0.75
0.75/15= 0.05

Answers
Answer:
200 degrees.
Step-by-step explanation:
By theorem of inscribed angle...
The measure of an inscribed angle is half the measure of the intercepted arc. [Theorem]
therefore, m(angle J) = half of m(arc CDE)
therefore, m(arc CDE) = 2 * m(angle J)
therefore, m(arc CDE) = 2 ( 100)
therefore, m(arc CDE) = 200 degrees.

Find the intercept and slope in the graph, and find the aquation for the function.
Answers
Answer:
Slope = 3
y intercept = -8
y = 3x - 8
Step-by-step explanation:
From the table shown, we can make use of the coordinate points
(0, -8) and (1, -5)
Slope m = y2-y1/x2-x1
m = -5-(-8)/1-0
m = -5+8/1-0
m = 3/1
m = 3
Slope = 3
The standard form of an equation is y = mx+b
b is the y intercept
Substitute m = 3 and (0, -8) into y = mx+b
-8 = 3(0) + b
-8 = b
b = -8
Hence y intercept is -8
Get the required equation
Recall that y = mx+b
y = 3x + (-8)
y = 3x - 8
This gives the required equation
An arctic wooly bear caterpiller lives for 7 years and spends 90% of its life frozen. How many days of its life is the arctic wolly bear frozen.
Answers
Answer:
The arctic wolly bear is frozen 2,299.5 days of its life.
Step-by-step explanation:
With the information provided, first, you have to calculate the number of days in 7 years by multiplying 7 years for 365 that is the number of days in a year:
7*365=2,555
Then, you have to calculate 90% of 2,555 since the statement indicates that the arctic wooly bear caterpiller spends 90% of its life frozen:
2,555*90%=2,299.5
According to this, the answer is that the arctic wolly bear is frozen 2,299.5 days of its life.

The radius of a circle is 3/4 inches. How many inches is the diameter?
Answers
Step-by-step explanation:
Given
In a circle
Radius (r) = 3 / 4 inches
Diameter (d)
= 2 * r
= 2 * 3 /4
= 3 /2 inches
Hope it will help :)❤
The diameter of a circle with a radius of 3/4 inches is 6/4 inches.
We are given that;
The radius of a circle = 3/4 inches
Now,
The diameter of a circle is twice the radius of the circle. Therefore, to find the diameter of a circle with a radius of 3/4 inches, we need to multiply 3/4 by 2. We can do this by multiplying the numerators and the denominators:
(3/4) x 2 = (3 x 2)/(4 x 2) = 6/8
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:
6/8 = (6/2)/(8/2) = 6/4
Therefore, by the circle the answer will be 6/4.

Answers
Answer:
The answer is B
Step-by-step explanation:
Given: Cory owes $1,000 to his bank. During the time of his loan, he is charged a real of 12% simple annual interest
To find: If he does not make any payments on his loan, draw table showing the relationship between the amount he owes and the number of months
Solution:
Loan amount P = $ 1000
Rate of interest R = 12 % per annum
SI = P * R * T /100
one month T = (1/12) Years
Interest per month = 1000 * 12 * (1/12) /100 = $ 10
Hence interest chaarges $ 10 per month
Cory owes to bank the loan amount and interest
Cory owes = 1000 + 10 n
where n is the number of months
Month Amount
0 1000
1 1010
2 1020
3 1030
4 1040
5 1050
