La suma de dos numeros es 208 y su diferencia es 122¿cuales son los numeros?

Answers

Answer:

Los números son:

43 y 165

Step-by-step explanation:

Planteamiento:

a + b = 208

a - b = 122

Desarrollo:

de la segunda ecuación del planteamiento:

a = 122 + b

sustituyendo este último valor en la primer ecuación del planteamiento:

(122+b) + b = 208

2b = 208 - 122

2b = 86

b = 86/2

b = 43

a = 122 + b

a = 122 + 43

a = 165

Comprobación:

165 + 43 = 208

165 - 43 = 122

1. A point is named or labeled using? 2. Three distinct points are collinear if ? 3. Three distinct points are coplanar if ? PLZ HELP

Answers

Answer:

1) A point P is named or labeled by using a coordinate pair, where the regular notation is:

P = (x, y).

Where x and y are the horizontal and vertical components.

2) Three distinct points are collinear if exists a line that passes through the 3 points.

3) Three distinct points are complanar if they are not collinear, this means that:

We can have two colinear points (so one line connects them) and another point outside that line.

Then the set of 3 points is coplanar.

A point has the coordinates (0, k).

Which reflection of the point will produce an image at the same coordinates, (0, k)?

Answers

Answer:

B

Step-by-step explanation:

I took the assignmen.

The reflection of point that will produce the image at same coordinate (0, k) is across the y - axis

We have a Point with coordinates  (0, k).

We have to find the reflection that will produce the image at the same coordinate (0, k).

Consider a Point P (x, y). Find the image of the point across x - axis and y - axis.

For a Point P [tex](x,y)[/tex] the image across -

x - axis is (x, -y).y - axis is (-x, y)

We can use the above laws to find the reflection of point

For Point P(0,k) , the -

image across x - axis will be (0, -k).image across y - axis will be (-0, k), which is same as (0, k).

Hence, the reflection of point that will produce the image at same coordinate [tex](0,k)[/tex] is across the y - axis.

Soccer ball profit
y=-6x^2 + 100x - 180
Suppose the store wants to earn a daily profit of $150 from the sale of soccer balls. To earn this profit, what price should the store charge for each soccer ball? Explain how to solve this problem.

Answers

Answer:

$8.33 per soccer ball.

Step-by-step explanation:

Y max is =236.67   is the max profit from the soccer balls. This goes on when you charge 8.33 a ball

Answer:

need to solve the equation 150 = -6x2 + 100x - 180. I can subtract 150 from both sides and use the quadratic formula to find x = 4.53 and 12.13. This means that if the store sells soccer balls for $4.53 or $12.13, it will earn a daily profit of $150.

Solve for y in 2y + 5 = - 3y - 10.*

Answers

Answer:

y = -3

Step-by-step explanation:

2y +3y = -10 -5 (collect the terms then calculate)

5y = -15 ( divide both sides )

then you'll get your answer which is y = -3

the answer is 3 because you have to cancel each other so 2y-2y which equals 0 and then you bring the 2y over to -3y and -3y-2y equals to 5y. then you have to cancel 5 out and you do 5-5 which equals 0 then -5-10 which equals 15. then you want to divide 15 and 5y which equals to 3. i hope this helps :)
