The measure of ∠EBD from the given figure is 26°.

Given that, m∠ABD=104°, BC bisects ∠ABD, and BE bisects ∠CBD.

An angle bisector is defined as a ray, segment, or line that divides a given angle into two angles of equal measure. The word bisector or bisection means dividing one thing into two equal parts.

Since BC bisects ∠ABD, we get ∠ABC=∠CBD

So, ∠ABD=∠ABC+∠CBD

⇒2∠CBD=104°

⇒∠CBD=52°

Here, BE bisects ∠CBD, we get ∠CBE=∠EBD

So, ∠CBD=∠CBE+∠EBD

⇒2∠EBD=52°

⇒∠EBD=26°

Therefore, the measure of ∠EBD from the given figure is 26°.

Answer: x=700+15

Step-by-step explanation: an educated guess

Answer:

y = 15x + 700

Explanation:

In this sentence said Max already has $700 which means it should be constant value in the equation. Max earns $15 for each lawn he cuts.

Linear equation:

where 'm' is rate of change, 'b' is constant value

So, the equation should be (for total money Max saved):

where y represents total money Max saved and x = number of lawns cut.

Using algebraic expressions and equations to solve this problem, there are 15 apartments with 2 rooms and 5 apartments with 3 rooms.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

If there are 20 apartments, we can write the equation for the sum of two different kind of apartments.

let x = number of apartments with 2 rooms

y = number of apartments with 3 rooms

x + y = 20     (equation 1)

If there are x apartments with 2 rooms and y apartment with 3 rooms and there are 45 rooms in total, we can express this as the equation:

2x + 3y = 45     (equation 2)

Rewriting equation 1 as an equation of y in terms of x,

x + y = 20     (equation 1)

y = 20 - x

Substitute this expression of y to equation 2, and solve for x.

2x + 3y = 45     (equation 2)

2x + 3(20 - x) = 45

2x + 60 - 3x = 45

-x = 45 - 60

-x = -15

x = 15

Substitute the value of x in either equation 1 or 2 and solve for y.

x + y = 20     (equation 1)

15 + y = 20

y = 20 - 15

y = 5

If x is the number of apartments with 2 rooms and y is the number of apartments with 3 rooms, then there are 15 apartments with 2 rooms and 5 apartments with 3 rooms.

Answer:

1. DNE

2. DNE

3. (-2, inf)

4. (-3,-2)

Step-by-step explanation:

The slope intercept form of the equation 12x ₊ 8y = ₋24 is

y = ₋3/2 x ₋ 3

Given the equation is 12x ₊ 8y = ₋24

we are asked to convert the given equation into slope intercept form.

Finding a line's equation requires using the slope-intercept form of a straight line. We must know both the line's slope and the point at which the line crosses the y-axis in order to use the slope-intercept formula.

12x ₊ 8y = ₋24

⇒ 12x ₊ 8y ₊ 24  = 0

we re-arrange the equation of the line to write it in the standard form

y = mx + b.

12x ₊ 8y = ₋24

8y = ₋12x ₋ 24

now divide the terms on the right side by 8.

y = ₋12x/8 ₋ 24/8

y = ₋3/2x ₋ 3

hence we get the slope intercept form as y = ₋3/2x ₋ 3, where m=s₋3/2 and b = ₋3

We need to know about rate of change to solve the problem. The rate of change of population between 2002 and 2004 is -6.098% . The rate of change of population between 2002 and 2006 is -4.88%

The rate of change of something can be calculated by dividing the difference between the final amount and the initial amount by the initial amount. Rate of change is usually calculated as a percentage. We can calculate rate of change of population per year or between any two years. In this question we need to find the rate of change between 2002 and 2004 and also between 2002 and 2006. The initial population in 2002 is 82 and in 2004 it is 77.

rate of change between 2002 and 2004=[tex]\frac{77-82}{82}[/tex]x100=[tex]\frac{-5}{82}[/tex]x100=-6.098%

rate of change between 2002 and 2006=[tex]\frac{78-82}{82}[/tex]x100=[tex]\frac{-4}{82}[/tex]x100=-4.88%

Therefore the rate of change of population between 2002 and 2004 is -6.098% and the rate of change of population between 2002 and 2006 is -4.88%, the rate of change is negative because the population decreases.

Given:

To find: Equation of the line.

Finding:

Let the equation of the line be: (y - y') = m (x - x'),

where, (x',y') = point through which the line passes and m = slope of the line.

The slope of the first line = [tex]\frac{1}{0}[/tex] , i.e., the y-intercept of this line does not exist and it is a vertical line.

Hence, the equation of the line is 0 = 1 (x - x')

Slope of line PQ = -3

Slope of line RS = 3

They are neither parallel nor perpendicular.

If two lines are parallel to each other, they would have the same slope value.

If two line are perpendicular, the slope value of one would be the negative reciprocal of the other.

Slope = change in y / change in x.

Slope of line PQ = (-1 - 14) / (2 - (-3))

Slope of line PQ = -15/5 = -3

Slope of line PQ = -3

Slope of line RS = (-10 - 8) / (-2 - 4)

Answer:

∠ NST = 59°

Step-by-step explanation:

∠ NST and ∠ LSN form a right angle , that is

∠ NST + ∠ LSN = 90

3x - 1 + 2x - 9 = 90

5x - 10 = 90 ( add 10 to both sides )

5x = 100 ( divide both sides by 5 )

x = 20

Then

∠ NST = 3x - 1 = 3(20) - 1 = 60 - 1 = 59°
