In ^CDE, DE= CD and m/D = 29°. Find m/C.

This is a way we can organize a linear equation:

[tex]y=mx+b[/tex]

We're given:

[tex]12x + 4y = 8[/tex]

To organize this equation in slope-intercept form, we have to focus on isolating y:

[tex]12x + 4y = 8\\4y = - 12x +8\\y = - 3x +2[/tex]

[tex]y = - 3x +2[/tex]

The answer is y= negative 3 plus 2

By using properties of angles, it is obtained that

x = 18.5°, y = 37°

Angle

When two straight lines intersect, an angle is formed. The point of intersection is called the vertex of the angle and the lines are called the arms of the angle.

Here,

[tex]\angle COF = 90^{\circ}\\[/tex]

By the problem,

4x + 90  + 16 = 180 [Angle on a straight line]

4x + 106 = 180

4x = 180 - 106

4x = 74

[tex]\\x = \frac{74}{4}\\x = 18.5^{\circ}[/tex]

AB and CD are straight lines

[tex]\angle DOB = 16^{\circ}[/tex]  [Vertically opposite angle]

By the problem,

90 + 2y + 16 = 180 [ Angle on a straight line]

2y  + 106 = 180

2y = 180 - 106

2y = 74

[tex]y = \frac{74}{2}\\y = 37^{\circ}[/tex]

Answer:

x=25

vertical angles are congruent so

4x-25=75

+25

4x=100

÷4

x=25

Answer:

x = 25°

Step-by-step explanation:

We know that,

→ opposite angles are equal.

Forming the equation,

→ (4x - 25)° = 75°

Now the value of x will be,

→ (4x - 25)° = 75°

→ 4x = 75° + 25°

→ x = 100°/4

→ [ x = 25° ]

Hence, the value of x is 25°.

Answer:

The polar form is

r = √11a

Explanation:

The given equation is

x^2 + y^2 = 11a

Recall,

x = rcosθ

y = rsinθ

By substituting these values into the equation, we have

(rcosθ )^2 + ( rsinθ)^2 = 11a

r^2cos^2θ + r^2sin^2θ = 11a

r^2cos^2θ + r^2sin^2θ - 11a = 0

By factorizing r^2, we have

r^2(cos^2θ + sin^2θ) = 11a

Recall, cos^2θ + sin^2θ = 1

Thus, we have

r^2 = 11a

Taking the square root of both sides,

r = √11a

The polar form is

r = √11a

Represents the quadratic equation y=x²-4x-12 with D > 0 . So the equation represents 2 zeros which comes to be 6 and -2.

What is Quadratic equation ??

A second-degree polynomial equation, which must contain at least one squared component, is what is known as a quadratic. Quadratic equations is another name for them. The quadratic equation's general form is as follows:

ax + by +c = 0

To draw the graph of quadratic equation:

Given quadratic equation,

x²-4x-12 = y

Put y = 0

So we get zeros as 6 and -2

Hence the graph will  cut the X axis at 6 and -2

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

In​ 2005, 10.9 out of every 50 employees at a company were women.

Now,

Since, In​ 2005, 10.9 out of every 50 employees at a company were women.

Let number of women's in 41,646 total company​ employees = x

So, We can formulate by the definition of proportion as;

⇒ 10.9 / 50 = x / 41,646

Solve for x as;

⇒ 10.9 × 41,646 / 50 = x

⇒ x = 9,078.83

Milo needs to cover 12 miles in 48.6 minutes, as the percentage.

What is percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. The percentage refers to one in a hundred. The % sign is used to denote it.

Milo can run 12 miles in 60 minutes.

She needs to reduce the time by 19%

So we have to calculate the 19%of 60

= 19/100* 60

=57/5 minutes

= 11.4

So the time he needs to achieve will be 60-11.4 = 48.6 minutes.

[tex]1\frac{5}{7}\text{ lb}[/tex]

Step-by-step explanation:

First, convert [tex]2\frac{1}{7}\text{ lb}[/tex] to an improper fraction (to make the math easier):

[tex]2\frac{1}{7}=\frac{15}{7}\text{ lb}[/tex]

Next, since the question asks about how much salmon is left over, find that fraction. After cooking one-fifth of the salmon, four-fifths remain:

[tex]\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]

Then, multiply the two:

[tex]\frac{15}{7}\times\frac{4}{5}=\frac{60}{35}\text{ lb}[/tex]

Finally, convert back to a mixed fraction:

[tex]\frac{60}{35}\text{ lb}=1\frac{25}{35}\text{ lb}=1\frac{5}{7}\text{ lb}[/tex]

y+1=6/11(x+4) is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are  (7, 5) and (−4, −1)

m=-1-5/-4-7

=-6/-11

=6/11

The point slope intercept form is y- y₁=m(x-x₁) through (-4,-1)

y-(-1)=6/11(x-(-4))

y+1=6/11(x+4)

Hence, y+1=6/11(x+4) is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1).

A. Write an equation to showing relationship between x and y:

The equation for the relationship between x and y is

3x + 2y = 30

The equation can be used for "the total cost of buying x chocolate bars, such that each one costs $3.50"

Here we have the linear equation:

y = 3.5*x

And we want to make a word problem that can be represented by this.

The simplest example would be something like "the total cost of buying x items of a cost equal to the constant of proportionality"

So let's suppose that there is a chocolate bar in a given store that costs $3.50 per unit.

So, if you buy x of these, the total cost will be modeled (in dollars) by the equation:

y = 3.50*x

Which is the same equation that we have above:

y = 3.5*x
