Answer:
El modelo lineal del comportamiento de producción de autos es y=69*x -136865
Step-by-step explanation:
Una función real de variable real es una función lineal si es de la forma f(x)=mx+n o y=mx+n. Es decir, la ecuación de la función se corresponde con un polinomio de primer grado. La representación gráfica de una función lineal es siempre una recta. El coeficiente m recibe el nombre de pendiente de la recta y será el responsable de lo inclinada o “pendiente” que se encuentre la recta respecto del eje X mientras que b es el intercepto con el eje Y.
Teniendo dos puntos (x1,y1) y (x2,y2) se puede calcular la pendiente mediante la expresión:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Para encontrar el valor de b, una vez reemplazado el valor de m en la ecuación se sustituye los valores de x y de y por los valores de las coordenadas de uno de los puntos, sea el uno o el dos y se despeja b para así obtener su valor.
En este caso y representará la producción de autos mientras que x cada año de producción. Entonces se tiene los siguientes puntos: (2000; 1135) y (2010; 1825)
Por consiguiente, el valor de m será:
[tex]m=\frac{1825-1135}{2010-2000}[/tex]
m=69
Entonces: y=69*x + b. Eligiendo el punto (2000; 1135) y reemplazando:
1135= 69*2000 + b
Se obtiene que el valor de b es:
1135= 138000 + b
-136865= b
Entonces el modelo lineal del comportamiento de producción de autos es y=69*x -136865

A professional hockey team has 15 wingers. 5 of these wingers are 30-goal scorers. Every fall the team plays an exhibition game with the club’s farm team. In order to make the match more interesting for the fans, the coaches agree to select two wingers at random from the pro team to play for the farm team. What is the probability that two of the 30-goal scorers are selected to play for the farm team?

Step-by-step explanation:
The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19
Gemma earns $575 a week plus $180 commission for each car she sells. She earned
$1835 last week. How many cars did she sell?
O She sold 6 cars.
O She sold 7 cars.
O She sold 8 cars.
O She sold 9 cars.
Answer:
7 cars
Step-by-step explanation:
Gemma earns $575 a week plus $180 in commission for each car sold
She earned $1835 last week
Therefore the amount of cars sold can be calculated as follows
= $575 + $180(7)
= $575 + $1260
= $1835
Hence 7 cars were sold

Answer:
Keaton solved it right.
Step-by-step explanation:
Both students did the first step correctly, but Emily divided on the last step instead of multiplying. When there is a division on the other side of the equation, you would have to multiply the denominator on both sides. Keaton correctly multiplied the denominator of 3 on each side which gives 12 * 3 = 36.
I really hope this helps! :)
Answer:
Keaton is correct.
Step-by-step explanation:
w/3 + (-2) = 10
+2 +2
w/3 = 12
multiple 3 on both sides to get rid of the fraction bc fraction means division
w = 36

Answer:
The coordinates of point P are (1, -1)
Step-by-step explanation:
If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)→ Assume that the coordinates of point P are (x, y)
∵ The coordinates of point P are (x, y)
∵ The rule of the reflection is R y-axis (P)
∴ Its image = (-x, y)
∵ The image = (-1, -1)
→ Equate the two images
∴ (-x, y) = (-1, -1)
∴ -x = -1
→ Divide both sides by -1
∴ x = 1
∵ y = -1
∴ The coordinates of point P are (1, -1)

Solve the following equation for x. -5(x + 4)= 12 – 40 – 70
Answer:
x = 78 /5
Step-by-step explanation:
5(x+4)=12-40-7x
Subtract the numbers from the left side which will equal -25-7x
Then... Distribute the -5 to x and 4 making the equation on the left
-5x -20
In all your equation should look like this
-5x -20 = -25 -7x
Then add 7x to the right side and add 20 to the left making the equation
-5x + 7x = -28 + 20
The add up the terms on each side...
2x = -8
Then divide the 2 to the left side...
Overall:
x= -4

A company's profits for a week are as follows:
Monday: +$32.65, Tuesday: -$75.32,
Wednesday: -$125.75, Thursday: +$100.89,
and Friday: +$65.30. Does the company show
a gain or loss at the end of the week?
Answer:
Loss
Step-by-step explanation:
If you add all the numbers up you get -2.23 which would be a loss
Answer:
The company shows loss
Step-by-step explanation:
32.65 - 75.32= -42.67 so they're already at a loss
you would add -125.75 and -42.67 and woud get -168.42
Then you would add 100.89 and 65.30 and you would get 166.19
166.19+(-168.42)=-2.23
