Concluimos que a partir de 21 piezas se gana más en la empresa B.
¿Cuanto debe vender para que le paguen más en la empresa B?
Si definimos el número de piezas vendidas como x, la cantidad que le pagan en la empresa A es:
A(x) = $6000 + $20*x
Y lo que le pagan en la empresa B es:
B(x) = $6000 + x^2
Queremos ver para que valor de x, se da que B(x) > A(x).
Entoces resolvamos esa inequación.
6000 + 20*x < 6000 + x^2
20x < x^2
20 < x
x debe ser más grande que 20, entonces concluimos que a partir de 21 piezas se gana más en la empresa B.

A salt-water tank needs to contain 5 gallons of water for each 1-inch fish. If lan has a 30-gallon tank, predict how many inch-long fish he can have. S
Answer:
6in
Step-by-step explanation:
Let's organize what we know.
- 5gal/1in
- 30gal tank
Since we need to find the inches of the fish he can have, we can set up a proportion like this:
5/1=30/x
We can cross multiply.
5x=1(30)
Simplify: 1*30=30
5x=30
Now we can isolate the variable.
5x=30

A real estate agent is trying to find the average credit score of some of her clients. She compiled the scores in the table below. What is the mean credit score in this group? (Round to the nearest whole point, if applicable. ) 787 615 550 674 784 773 620 720 704 a. 668 b. 784 c. 692 d. 704 Please select the best answer from the choices provided A B C D.
Answer:
Step-by-step explanation:
First Add the scores.
Score Total = 787 + 615 + 550 + 674 + 784+ 773 + 620 + 720 + 704
Score Total = 6227
Now divide by the number of members of the sum.
Number of members = 9
The average score = Total Score / number of members
The average score = 6227 / 9 = 691.9
The average score = 692 which is C

The equation of a linear function is y = –2x + 3. Which table contains a set of points that lie in the graph of this function?
Answer:
The answer is A)
Step-by-step explanation:
To find out table contains a set of points that lie in the graph of this function , we have to hit and trial method ,
when we put the value of x in y = –2x + 3 this equation so ,
taking x = 1 , then the value of y is
=> y = -2(1)+3
=> y = -2+3
=> y = 1
taking x = 0 , then the value of y is
=> y = -2(0)+3
=> y = 3
now talking x = -3 , then the value of y is
=> y = -2(-3) +3
=> y = 6+3
=> y = 9
so , the option A is the right answer
Answer:
A)
Step-by-step explanation:
Given linear function: y = -2x + 3
Therefore, the slope is -2 and the y-intercept is (0, 3)
Therefore, we are looking for a set of ordered pairs that has a rate of change of -2
⇒ as the x-value increases by 1 unit, the y-value decreases by 2 units
i.e. as the x-value decreases by 1 unit, the y-value increases by 2 units.
The only set of ordered pairs that follows this rule is A)
Let's check by substituting the values of x = 1, x = 0 and x = -3 into the function:
when x = 1 → -2(1) + 3 = 1
when x = 0 → -2(0) + 3 = 3
when x = -3 → -2(-3) + 3 = 9
Confirming that the set of ordered pairs in A) lie on the graph of the given function.
Use the similar triangles on the coordinate plane to determine the equation for the given line. Y = three-fourths x y = four-thirds x y = 4x 3 y = 3x 4.
The equation of the line plotted in the graph with the similar triangles on the coordinate plane is y equal to three-fourths x.
Symbolically, it can be written as,
[tex]y=\dfrac{3}{4}x[/tex]
What is the equation of line?The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
[tex]y=mx+c[/tex]
Here, (m) is the slope of the line and (c) is the y intercept.
The similar triangles on the coordinate plane to determine the equation for the given line. The line and the triangle is graphed in the image attached below.
The line passes from origin point (0,0). The coordinate points on the line say P are (4,3) as shown in the image. Thus, for this the slope of the line can be given as,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\m=\dfrac{3-0}{4-0}\\m=\dfrac{3}{4}[/tex]
The equation of the line for 3/4 slope is,

What is bankruptcy?
Bankruptcy is the procedure by which the people who are unable to pay the debts to creditors, may get relief from some or all the debts.
Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans.
Nellie took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. Thus, the interest is,
[tex]I=\dfrac{45000\times6\times15}{100}\\I=40500[/tex]
If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. In this case, the interest paid would be,
[tex]I=\dfrac{45000\times6\times6}{100}\\I=16200[/tex]
The difference between the interest paid would be,
[tex]I=40500-16200\\I=24300[/tex]
Hence, the amount more in interest over the life of the loan which Nellie have to pay is $14814.

For which values of c does the quadratic equation x^2-2x +c=0 have
One root equal to zero and one negative root
Answer:
There is no values of c that makes it true
Step-by-step explanation:
The roots of the quadratic equation x² – 2x + c = 0 are 0 and –2. Then the value of c is zero.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
For which values of c does the quadratic equation
x² – 2x + c = 0 ...1
The one root is equal to zero and one negative root.
Let negative a be the one root.
x = 0, –a
Then we have factorized the equation,
(x)(x + a) = 0
On solving, we have
x² + ax = 0 ...2
In comparing equation 2 with equation 1, we have
a = –2 and c = 0

There are two jars.
One jar has 2 red, 3 green and 1 yellow gumball.So, there are 2+3+1=6 gumballs.
Another jar has 2 blue and 3 purple balloons. Totally there are 2+3=5 balloons.

Answer:
Yes, he is correct, 240 miles will require a gas volume of 13.71 gallons which is less than 15 gallons in Enrique's car.
Step-by-step explanation:
Given;
total volume of gas in Enrique's car, V = 15 gallons
The rate of gas consumption [tex]= \frac{35 \ miles}{2 \ gallons} = 17.5 \ miles/gallon[/tex]
To drive 240 miles, he would need the following volume of gas;
[tex]V = 240 \ miles* \frac{1}{\frac{17.5 \ miles}{gallon} }\\\\ V = 240 \ miles*\frac{1*gallon}{17.5 \ miles}\\\\ V = (\frac{240 \ miles}{17.5 \ miles} )gallon\\\\V = 13.71 \ gallons[/tex]
The volume of gas needed to drive 240 miles is less than the total volume of gas in Enrique's car.
Thus, he is correct
