Step-by-step explanation:

x = 2y-1

2x = 4y-2

4y - 2 = 3y + 2

y = 4

x = 2(4) - 1

Answer:

The discriminant is 76

Step-by-step explanation:

The equation needs to be in the form

ax^2 +bx +c =0

3x^2 - 6 = 2x

Subtract 2x from each side

3x^2 -2x - 6 = 0

The discriminant is

b^2 - 4ac

a = 3  b = -2  c = -6

(-2)^2 -4(3) (-6)

Answer:

y = 3/4 x +6

Step-by-step explanation:

3x−4y=−24

Solve for y

Subtract 3x from each side

3x-3x−4y=-3x−24

-4y = -3x-24

Divide each side by -4

-4y/-4 = -3x/-4 -24/-4

y = 3/4 x +6

Answer:

a. 30%

b. $893.59

c.

Answer:

a. 30%

b. $893.59

c.

Step-by-step explanation:

a. Given that the carpet costs $427.35, the labor costs $212.52 and other flooring supplies costs $75.

#To get the  percent of the flooring bill that will go towards the cost of labor:

Hence, labor costs 30% of the total flooring costs.

b.The total flooring costs is :

Given that she spends 25% more on furniture than on flooring, we multiply the flooring cost by 125% to get the furniture costs:

Hence, she spends $893.59 on furniture.

c.To get what percentage of  furniture cost was the night stand.

-Given the total furniture cost is $893.59:

Let x be the cost of the dresser and y the cost of the nightstand;

The percentage is then calculated as:

Hnece the percentage cost of the night stand is

12x+20/5y³

Step-by-step explanation:

y³ is divided by y⁶ so it leaves y³ at the below and it produces with 5 so we have 5y³ at below. On the above we should not use y³ because it's already divided by y⁶ so we produce 4 and 3x+5 it gives us 12x+20 so the answer is 12x+20/5y³

Answer:

6^2

Step-by-step explanation:

The equation gives you 36.

36 is 6 raised to the power of 2.

You just solve it by observation.

The value of [tex]10^2-4^3 \ is\ 6^2[/tex]

Given that,

Based on the above equation, we need to solve it

[tex]= 10^2-4^3[/tex]

= 100 - 64

= 36

[tex]= 6^2[/tex]

Basically we deduct it so that the value could come in a power of 6.

Therefore we can conclude that the value of [tex]10^2-4^3 \ is\ 6^2[/tex]

cos300° = 0.5 if you want a numerical value .....

Step-by-step explanation:

Answer:

1/2

Explanation:

Exact value means put the calculator away and go to an x/y coordinate plane.  Set the angle up in standard position with the initial ray on the positive x-axis and the terminal ray will move counterclockwise around until is sweeps out a 300 degree angle.  That angle will be in the fourth quadrant, 60 degrees BELOW the x-axis you started on.  But we are not using the negative value, which is measured clockwise.  From the negative y axis that is the 270 degree line, we add 30 to that 270 and get the 300 degree angle we want.  Angles are always measured from the terminal ray to whichever x-axis its closest to.  From the terminal ray to the x-axis forms a 60 degree angle.  That means that the reference angle is 60.  The side across from a 60 degree angle in a 30-60-90 right triangle is square root of 3, but our side is in the negative y's so it is  .  Along the x axis is the side across from the 30 degree angle which is a +1.  The hypotenuse is 2.  These values are from the Pythagorean triple for a 30-60-90 right triangle and should be familiar at this point.  The cos identity is the side adjacent to the reference angle over the hypotenuse  so our exact value for cos 300 is 1/2.

Answer:

Correct option: 3

Step-by-step explanation:

When we have a crossing of two chords in a circle, there is a property that relates the angles in the intersection point and the arcs defined in the circle. From this property, we have that:

mAEC = (1/2) * (mAC + mBD)

Using the values of mAEC = 58° and mAC = 72°, we have that:

58 = (1/2) * (72 + mBD)

116 = 72 + mBD

mBD = 116 - 72

mBD = 44°

Answer:

(B)$671.37

Step-by-step explanation:

Interest Rate, r=15%=0.15

Time, t = [tex]\dfrac{80}{365}[/tex]

Maturity Value at exact interest, S=P(1+rt)

[tex]=\$650 \left (1+0.15*\dfrac{80}{365}\right)\\\\=\$671.37[/tex]

The correct option is B.

Step-by-step explanation:

r − r cos θ = 6

r = r cos θ + 6

r² = (r cos θ + 6)²

x² + y² = (x + 6)²

x² + y² = x² + 12x + 36

y² = 12x + 36

The rectangular form of the polar equation is x² + y² = 2x + y - 2.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

To convert a polar equation to rectangular form, you can use the following relationships between polar and rectangular coordinates:

x = r x cos(theta)

y = r x sin(theta)

where r is the distance from the origin to the point in polar coordinates, and theta is the angle between the positive x-axis and the line connecting the origin and the point.

Now,

So, if you have a polar equation in the form of r = f(theta), you can substitute these expressions for x and y into the equation to obtain a rectangular equation in terms of x and y.

The resulting equation will typically be a function of x and y, rather than just one variable as in the polar form.

For example,

If you have the polar equation r = 2 + sin(Ф), you can substitute x = rcos(Ф) and y = rsin(Ф) to get:

x = (2 + sin(Ф)) x cos(Ф)

y = (2 + sin(Ф)) x sin(Ф)

Simplifying these expressions using trigonometric identities, you can get the rectangular form of the polar equation:

x² + y² = 2x + y - 2

Thus,

The rectangular form of the polar equation is x² + y² = 2x + y - 2.

Answer:

7.73

Step-by-step explanation:

In the picture attached, the diagram is shown.

Area of square = side² = 6² = 36 in²

The non-shaded area is quarter the area of the circle's area with radius = side of the square. This area is: (1/4)*π*radius² = (1/4)*π*6² = 28.27 in²

Therefore, the shaded area is: Area of square  - non-shaded area  = 36 in² - 28.27 in² = 7.73 in²
