Answer:

x = 35/36

Step-by-step explanation:

3(x-1/4) = 13/6       Distribute

3x-3/4=13/6          Add 3/4 on both sides

3x = 35/12            Divide by 3 on both sides

x = 35/36

Answer:

x = 17/36

Step-by-step explanation:

3(x - 1/4) = 13/6

3x - 3/4 = 13/6

Make common denominators by multiplying 3/4 by 6/6 and 13/6 by 4/4 to get:

3x - 18/24 = 52/24

Now subtract 18/6 from both sides to get:

3x = 34/24

3x = 17/12 or 1 15/12

To find x, divide both sides by three to get:

x = 17/36

Answer:

y = -6x/12 + 9/12 trust me bro I'm good at this

Answer:

[tex]y=-\frac{x}{2}[/tex] + [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

6x + 12y=9

Subtract 6x from both sides.

12y=9-6x

Divide both sides by 12.

[tex]\frac{12y}{12}[/tex]=[tex]\frac{9-6x}{12}[/tex]

Dividing by 12 undoes the multiplication

[tex]y=\frac{9-6x}{12}[/tex]

Divide 9 - 6x by 12

[tex]y=-\frac{x}{2}[/tex] + [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

If this is a question involving a quadratic, then the answer is

x^2 - 24x - 25

(x - 25)(x + 1)

If it is any other situation, I don't think so. Factors imply division and usually you are speaking about integers.

A) A year is 12 months. Multiply monthly pay by 12 for yearly amount:

4500 x 12 = $54,000 per year.

B) the monthly rate of 4,500 per month pays more by: 54,000 - 53,210 = $790 per year

The working capital and the current ratio are :

$90; 0.55

Using this formula

Working capital=Current Assets- Current Liabilities

Where;

Current Assets=$110

Current Liabilities=$200

Let plug in the formula

Working capital=$110-$200

Working capital=$90

Current Ratio=Current Assets/Current Liabilities

Let plug in the formula

Current Ratio=$110/$200

Current Ratio=0.55

Inconclusion The working capital and the current ratio are : $90; 0.55

Since E is the midpoint of DF, DE and EF are two halves of DF. First, let's write down what we know.

DE = 3x + 4

EF = 5x - 2

DE = EF

DE + EF = DF

Now, let's plug our values for DE and EF into our first expression.

3x + 4 = 5x -2

Add 2 to both sides and subtract 3x from both sides.

6 = 2x

Divide both sides by 2

3 = x

Let's plug 3 in for x into DE.

DE = 3x + 4 = 3(3) + 4 = 9 + 4 = 13

DE = EF = 13

We can plug 13 in for DE and EF to get DF

DF = DE + EF = 13 + 13 = 26

Answer:

first answer!

Step-by-step explanation:

domain: all real numbers

range: all real numbers greater than or equal to 5!

a) The x-coordinates of the points A and B are [tex]x_{A} = 11[/tex] and [tex]x_{B} = -7[/tex].

b) The point of intersection of the tangents to the circle at A and B is [tex](x,y) = (2, 27)[/tex].

a) In this part we simplify the equation of the circle and solve for [tex]x[/tex] to determine the coordinates associated to the required points:

The coordinates of the two points so that circle intersects the x-axis, occurs when the following condition is met:

[tex]f(x, 0) = 0[/tex] (1)

Where [tex]f(x,y)[/tex] is in implicit form.

If we know that the equation of the circle is [tex]x^{2} + y^{2} - 4\cdot x + 6\cdot y - 77 = 0[/tex] and [tex]y = 0[/tex], then the reduced equation is:

[tex]x^{2} - 4\cdot x - 77 = 0[/tex] (2)

And we obtain the x-coordinates of the points by factoring (2):

[tex](x-11) \cdot (x + 7) = 0[/tex]

The x-coordinates of the points A and B are [tex]x_{A} = 11[/tex] and [tex]x_{B} = -7[/tex].

b) Lines are defined by both slope and intercept. Slope is defined by implicit differentiation and intercept is found by equation of the line.

Given that [tex]A(x,y) = (11, 0)[/tex] and [tex]B(x,y) = (-7, 0)[/tex], we determine line equations corresponding to each tangent line:

Slope

[tex]2\cdot x + 2\cdot y \cdot \dot y - 4 + 6\cdot \dot y = 0[/tex]

[tex](2\cdot y + 6)\cdot \dot y = 4 - 2\cdot x[/tex]

[tex]\dot y = \frac{2 - x}{y + 3}[/tex]

Point A

[tex]\dot y = \frac{2-11}{0 + 3}[/tex]

[tex]\dot y = -3[/tex]

Point B

[tex]\dot y = \frac{2-(-7)}{0 + 3}[/tex]

[tex]\dot y = 3[/tex]

Intercept

Point A ([tex]A(x,y) = (11, 0)[/tex], [tex]\dot y = -3[/tex])

[tex]b = y - m\cdot x[/tex]

[tex]b = 0 - (-3)\cdot (11)[/tex]

[tex]b = 33[/tex]

Point B ([tex]B(x,y) = (-7, 0)[/tex], [tex]\dot y = 3[/tex])

[tex]b = y - m\cdot x[/tex]

[tex]b = 0 - 3\cdot (-7)[/tex]

[tex]b = 21[/tex]

The equations of the lines tangent to the circle are:

[tex]y = -3\cdot x +33[/tex] (3)

[tex]y = 3\cdot x +21[/tex] (4)

The point of intersection is the solution of this system of linear equations:

[tex](x,y) = (2, 27)[/tex]

The point of intersection of the tangents to the circle at A and B is [tex](x,y) = (2, 27)[/tex].

9514 1404 393

Answer:

  x ≠ 3

Step-by-step explanation:

In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.

The domain is all real numbers except x=3.

Additional comments

It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.
