Michael chose some positive number, multiplied it by itself, added 1, multiplied the result by 10, added 3, and multiplied the result by 4. His final answer was 2012. What number did Michael choose?

Answer:

It would cost $ 408.04 to travel 2727 miles

Divide total miles by miles per gallon:

2,727 / 27 = 101 gallons.

Multiply total gallons by price per gallon:

101 x 4.04 = $408.04  Round as needed.

Answer:

y = -y

Step-by-step explanation

So since we know that the answer of this question turns out to be a positive, and 5 is a negative number, that means y is negative. Heres my reason why:

( write this down on your essay)

Since a negative number and another negative number added becomes a positive, y would be a negative number.

Therefore, It is true that y is a negative number

Answer:

x + y = - 2

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y - 2 = - (x + 4) ← distribute by - 1

y - 2 = - x - 4 ( add x to both sides )

x + y - 2 = - 4 ( add 2 to both sides )

x + y = - 2 ← in standard form

Answer:

Hi

Step-by-step explanation:

Step-by-step explanation:

x/(x + 2) + 1/x = 1

x² + (x + 2) = x(x + 2)

x² + x + 2 = x² + 2x

x = 2.

Since x = 2 neither makes (x + 2) or x become 0, there are no extraneous solutions.

The answer is "The equation has 1 valid solution and no extraneous solutions." (C)

The true statement is (c) the equation has one valid solution and no extraneous solutions

The equation is given as:

[tex]\frac{x}{x + 2} + \frac 1x = 1[/tex]

Take LCM

[tex]\frac{x^2 + x + 2}{x(x + 2)} = 1[/tex]

Expand the numerator

[tex]\frac{x^2 + x + 2}{x^2 + 2x} = 1[/tex]

Cross multiply

[tex]x^2 + x + 2 = x^2 + 2x[/tex]

Subtract x^2 from both sides

[tex]x + 2 = 2x[/tex]

Collect like terms

[tex]2x -x = 2[/tex]

[tex]x = 2[/tex]

Hence, the equation has one valid solution and no extraneous solutions

Answer:

150 cm^2

Step-by-step explanation:

Keep in mind that the dimensions of the cube are identical in 6 directions.  This means that the surface area of the bottom is 5 cm by 5 cm, yielding the area 25 cm^2.  The top has the same area, so considering top and bottom we get a total surface area of 50 cm^2.

Likewise, the total surface area of the sides together is 50 cm^2.  The total surface area of the front and back together is 50 cm^2.

Thus, the total surface area of the entirre cube is 3(50 cm^2), or 150 cm^2

The measure of angle U is 74 degrees.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

to determine the measure of angle U:

From the question, we have the following parameters that can be used in our computation:

△PQR ≅ △STU

If m ∠P = 62 degrees and m ∠Q = 45 degrees

The above parameters mean that

P  = S Q = T and R = U

So, we have

U = R = 180 - P - Q -- by the angles in a triangle theorem

So, we have

U = 180 - 61 - 45

   = 74

Evaluate

U = 74

Hence, the value of m ∠U is 74 degrees

Step-by-step explanation:

n - 3 = 2

When you transfer (-3) to the other side of the equation, it turns into (+3).

n = 2 + 3

Evaluate.

n = 5

n + 3 = 2

When you transfer (+3) to the other side of the equation, it turns into (-3).

n = 2 - 3

The system has of the equation has no solution

Thus,

NO SOLUTION!

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}y=-6x+2\\ -12x-2y=4\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y+6x=2\\ -2y-12x=4\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y+6x=2\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+12x=4[/tex]

so

[tex]\begin{bmatrix}2y+12x=4\\ -2y-12x=4\end{bmatrix}[/tex]

adding both equations

[tex]-2y-12x=4[/tex]

[tex]+[/tex]

[tex]\underline{2y+12x=4}[/tex]

Answer:

Mai travels 2.5 meters in 1 second

Priya travels 2.2 meters in 1 second

Step-by-step explanation:

Try finding how many meters they travel in ONE second) Mai and Priya were on scooters.

For Mai

Mai traveled 15 meters in 6 seconds.

Hence,

6 seconds = 15 meters

1 second = x meters

Cross Multiply

6x = 15 meters

x = 15/6

x = 2.5 meters

Hence, Mai travels 2.5 meters in 1 second

For Priya

Priya travels 22 meters in 10 seconds.

Hence,

10 seconds = 22 meters

1 second = x meters

Cross Multiply

10x = 22 meters

x = 22/10

x = 2.2 meters

Hence, Priya travels 2.2 meters in 1 second

Answer:

-10

Step-by-step explanation:

the equation is in y=mx + b form so the b is the y-intercept so therefore it is -10

Answer:

A

Step-by-step explanation:

both equation is y so

2x - 5 = x² - 5

2x = x²

0 = x² - 2x

0 = x(x-2)

x = 0

x = 2

for x = 0

y = 2x - 5

y = 0 - 5

y = -5

(0,-5)

for x = 2

y = 2x - 5

y = 2(2) - 5

y = -1

(2,-1)
