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.

=(x+y) [(x+y) +3]

=(x+y) (x+y+3)

(x + y) (x + y+3) is the factorized form of (x + y)² + 3(x + y)​

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)​

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.

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

Answer:

Step-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.

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

Answer:

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]

Answer:

C) 4

Step-by-step explanation:

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]

Answer:

[(6x5)÷2]x10x5x2=750

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.
