A company sells floats for children. An equation that models their profit is P=4x-10,000 , where x is the number of floats sold.
If 5,000 floats are sold, what is the company's profit?
Answers
Answer:
P = $10,000
Step-by-step explanation:
The equation modeling a company's profit is P = 4x - 10000.
Substitute x for 5,000.
P = 4(5,000) - 10,000
P = 20,000 - 10,000
P = 10,000
The company's profit will be $10,000 if 5,000 floats are sold.
The profit earned by a sporting goods outlet is modeled in the graph below, where x is the number of years since the outlet opened. He recorded the profit for the first 10 years since the outlet opened.
Answers
Answer:
Step-by-step explanation:
Vertex of the given parabola is (4, 160)
Since, graph of the parabola is increasing between x = 0 to x = 4,
Profit earned will be between t = 0 and t = 4
Therefore, domain represents the number of years.
Since, profit of the outlet (y-values) vary from x = 0 to x = 10
And value of profit varies from 0 to 160 thousand dollars, so the range of the function will be (0, 160)
Range of the function represents the outlet's profit.

Are the following systems equivalent? How do you know?
2x+y= -4 7x+7y=0
5x+6y= 4 4x+2y= -4
Answers
Answer:
No, they are not equivalentStep-by-step explanation:
Are the following systems equivalent? How do you know?
For the equation;
2x+y= -4 ... 1
7x+7y=0 ... 2
Let us find the solution of the equation;
From 1;
y = 4 - 2x
Susbtitutw into 2;
7x + 7(4-2x) = 0
7x + 28 - 14x = 0
-7x + 28 = 0
7x = 28
x = 28/7
x = 4
Recall that y = 4-2x
y = 4 - 2(4)
y = 4 - 8
y = -4
The solution is (4, -4)
For the other equations;
5x+6y= 4 ... 1 * 1
4x+2y= -4 ..... 2 * 3
___________________
5x+6y= 4
12x+6y= -12
Subtract
5x-12x = 4 + 12
-7x = 16
x = -16/7
Since the solutions to both simultaneous equations are different, hence the systems of equations are not equivalent.

Answers
Answer:
The correct graph is the first graph on the top left corner amongst the options
Step-by-step explanation:
The graph that shows that Cindy reads about 3/4 of the time while riding the car is given by the following relation;
Let 't' represent the time Cindy spend riding the car
Therefore, we are given that
The time Cindy spend reading = 3/4·t
Therefore, when Cindy rides the car for t = 4 hours, the time Cindy spend reading = 3/4·t = 3/4 × 4 = 3 hours
The coordinates of the point on the graph will therefore, be (4, 3)
Therefore, when the y-coordinate of the graph )the time Cindy spends reading) = 3, the x-coordinate of the graph (the time Cindy spends driving) = 4

✓Change in price= ($60 - $33)
=$27
✓percent change in price= change in price/ original price ×100%

Arcs on one side of the diameter adds upto 180°.
Therefore,
[tex](2 + 17x) \degree + 54 \degree + 56 \degree = 180 \degree \\ \\ (2 + 17x) \degree + 110 \degree = 180 \degree \\ \\ (2+ 17x) \degree = 180 \degree - 110 \degree\\ \\ (2 + 17x) \degree = 70 \degree \\ \\ 2 + 17x = 70 \\ 17x = 70 - 2 \\ \\ x = \frac{68}{17} \\ \\ x = 4[/tex]
Answer:
Choice C) 4
Step-by-step explanation:
You can do this in multiple different ways but I will do it in the way I believe will be the fastest.
So since we already know everything on one side of the line, we can use that to find x. The line is 180° and since the angles are on the line we know that they will all add up to 180.
For this we will need an equation:
[tex]2+17x+54+56=180[/tex]
Now we add the like terms:
[tex]112+17x=180[/tex]
Subtract the 112 on both sides:
[tex]17x=68[/tex]
Divide the 17 on both sides:
[tex]x=4[/tex]

What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given equation is (x + y)² + 3(x + y)
We know that (a + b)²=a²+b²+2ab
Similarly (x + y)²=x²+y²+2xy
Substitute this in above equation
x²+y²+2xy+3(x + y)
x²+y²+2xy+3x+3y
Factorising it we get
(x + y) (x + y+3)
Hence, (x + y) (x + y+3) is the factorized form of (x + y)² + 3(x + y)

isosceles = 2 equal angle
x + 10 + x + 10 + 3x = 180
5x + 20 = 180
5x = 160, x = 32
Plug in 32 for angle U
3(32) = 96
Solution: angle U = 96 degrees
Answer:
x=52
Step-by-step explanation:
since its an isosceles triangle, both sides are to have the same length.
so x+10+x+10+3x=180(all angles added in a triangle gives 180)
5x+20=180
5x=180-20
5x=160
x=160/5
x=52

The solution to the system of equations is:
[tex]x=\frac{25}{3},\:y=-\frac{11}{9}[/tex]
Step-by-step explanation:
Given the system of equations
[tex]5x + 3y = 38[/tex]
[tex]2x + 3y = 13[/tex]
solving the system of equations
[tex]\begin{bmatrix}5x+3y=38\\ 2x+3y=13\end{bmatrix}[/tex]
Multiply 5x+3y=38 by 2: 10x+6y=76
Multiply 2x+3y=13 by 5: 10x+15y=65
[tex]\begin{bmatrix}10x+6y=76\\ 10x+15y=65\end{bmatrix}[/tex]
so
[tex]10x+15y=65[/tex]
[tex]-[/tex]
[tex]\underline{10x+6y=76}[/tex]
[tex]9y=-11[/tex]
now solving 9y = -11 for y
[tex]9y=-11[/tex]
divide both sides by 9
[tex]\frac{9y}{9}=\frac{-11}{9}[/tex]
Simplify
[tex]y=-\frac{11}{9}[/tex]
For 10x+6y=76 plug in y = -11/9
[tex]10x+6\left(-\frac{11}{9}\right)=76[/tex]
subtract 6(-11/9) from both sides
[tex]10x+6\left(-\frac{11}{9}\right)-6\left(-\frac{11}{9}\right)=76-6\left(-\frac{11}{9}\right)[/tex]
[tex]10x=\frac{250}{3}[/tex]
Divide both sides by 10
[tex]\frac{10x}{10}=\frac{\frac{250}{3}}{10}[/tex]
[tex]x=\frac{25}{3}[/tex]
Therefore, the solution to the system of equations is:
[tex]x=\frac{25}{3},\:y=-\frac{11}{9}[/tex]

–5(s – 30) = –10
s = –4
s = 8
s = 28
s = 32
Answers
Answer:
s = 32
Step-by-step explanation:
-5 (s - 30) = -10
Apply distributive property.
-5s + 150 = -10
We need to get "s" alone. By getting it alone, subtract 150 from both sides.
-5s + 150 - 150 = -10 - 150
-5s = -160
Wait a second, there is still a -5 on the s. We need to get s alone. Divide both sides by -5 to get s alone.
-5/-5s = -160/-5
s = 32
s = 32 is your answer AKA the last one. I hope this helps! Let me know if I got anything wrong or if you need any more help.
A bakery makes small batches of bread daily. Each day, the bakery records the amount of flour used the number of loaves of bread made. All loaves are approximately the same size. The table and graph show the bakery’s data for five days.
write an equation that can be used to model the number of loaves of breast, y that can be made from x pounds flour
Use an equation to predict the number of loaves that can be made from 85 pounds of flour show your work or explain your answer
Answers
Answer:
The slope of the line would be the constant of proportionality for the line
shown. The point (35, 49) is really close the line which would make the
constant of proportionality 49/35 = 7/5. The equation of the line would be y =
7/5x. The number of loaves of bread from 85 pounds of flour would be
7/5(85) = 119 loaves.
Step-by-step explanation:
A ratio of the rise to a run, or the rise divided by run, is the slope of the line. It denotes how steep a line would be in the coordinate plane.
Slope calculation:This line's slope would be the proportional constant.This point (35, 49) is extremely near to the lines that would result in the linear constant [tex]\frac{7}{5} = \frac{49}{35}[/tex] , the line's equation is [tex]y = \frac{7}{5x}[/tex]. Using 85 pounds of flour, Calculate the loaves of bread that may be made [tex]\frac{7}{5(85)} = 119[/tex] loaves.Therefore, the equation was used to forecast the number of loaves that could be created from 85 pounds of flour, and the result was 119 loaves.Find out more about the slope here:
