Answer:

Step-by-step explanation:

(-5, 3) and (-5, -3)

(-3 - 3)/(-5 + 5) = -6/0 = UNDEFINED

That is also the CORRECT ANSWER

Using proportions, it is found that 96,734 more obese people were there in evansville than in boulder.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

For Evansville, the proportion of obese people is given by:

189/(311+189) = 189/500.

Hence, out of 358,676 people:

oE = 189/500 x 358676 = 135580.

For Boulder, the proportion is given by:

16/(16 + 109) = 16/125

Hence, out of 303,482 people:

oB = 16/125 x 303482 = 38846.

Hence the difference is given by:

135580 - 38846 = 96734

The solution to this system of equations is infinitely many solutions

The system of equations is given as:

-5.9x  -3.7y = -2.1.

5.9x + 3.7y = 2.1.

Add both equations to eliminate a variable

-5.9x + 5.9x - 3.7y + 3.7y = -2.1 + 2.1

Evaluate

0 +0 = 0

Evaluate the sum of zeros

0 = 0

Both sides of the equations are the same

Answer:

Option C is correct. The system of linear equation -5.9x - 3.7y =  -2.1 and 5.9x +3.7y = 2.1 have infinitely many solutions.

What is system of linear equation?

The system of linear equations is "a set of two or more linear equations or   variables is called system of linear equation".

What is infinitely many solutions?

An equation has infinitely many solutions only if "the two lines are coincident and having the same y-intercept".

According to the question,

The system of linear equation,

-5.9 x - 3.7y = -2.1            →  (1)

5.9 x + 3.7y = 2.1              →  (2)

The equation (1) is same as the equation (2) only the difference equation (1) is multiplied by (-1). Both equation give the same line. To check if above equations have same y-intercept, the equation can be written in slope intercept form y = m x +c where 'm' is the slope of the line, 'c' is the 'y-intercept'.

y = - (5.9/3.7) x + 2.1   [From equation (1)]

y = -(5.9/3.7) x + 2.1      [From equation (2)]

The both equation have same y-intercept. Therefore, the system of linear equations have infinitely many solution.

Hence, the system of linear equation -5.9x - 3.7y =  -2.1 and 5.9x +3.7y = 2.1 have infinitely many solutions.

Step-by-step explanation:

Using the distance formula, the perimeter of triangle ABC is approximately 40.5 units.

Perimeter = sum of all three sides.

Use the distance formula, [tex]d = \sqrt{(y_2 - y_1)^2 - (x_2 - x_1)^2}[/tex] to find the distance between each of the vertices of the triangle.

The given vertices are:

AB = √[(8−(−6))² + (−1−4)²]

AB = √221

AB ≈ 14.9 units

BC = √[(8−0)² + (−1−(−9))²]

BC = √128

BC ≈ 11.3 units

AC = √[(−6−0)² + (4−(−9))²

AC = √205

AC ≈ 14.3 units

Perimeter of △ABC = 14.9 + 11.3 + 14.3

Step-by-step explanation:

The defining property of a rhombus is that it has equal side lengths.

=============================================================

Finding all side lengths :

AB

⇒ √(-4 + 6)² + (5 - 4)²

⇒ √2² + 1²

⇒ √5 units

BC

⇒ √(-3 + 4)² + (3 - 5)²

⇒ √1² + (-2)²

⇒ √5 units

CD

⇒ √(-5 + 3)² + (1 - 3)²

⇒ √(-2)² + (-2)²

⇒ √8 units

DA

⇒ √(-6 + 5)² + (4 - 1)²

⇒ √(-1)² + 3²

⇒ √10 units

As all side lengths of the quadrilateral are not equal, ABCD is not a rhombus.

Answer:

y=2x-5

explanation

m is gradient so rise over run and b is the y intercept which is -5

Answer: y = 2x - 5

Step-by-step explanation:

Method I:

▪︎ Slope: m = (y2 - y1) / (x2 - x1)

▪︎ b is where the graph crosses the y-axis

▪︎ Points: (1, -3), (2, -1)

▪︎ m = (-1 - (-3)) / (2 - 1) = (3 - 1) / (1) = 2

▪︎ b = -5

▪︎ => y = 2x - 5

Method II:

▪︎ y = mx + b

▪︎ Points: (1, -3), (2, -1)

▪︎ System of equations:

-3 = m*1 + b,

-1 = m*2 + b

-3 = m + b,

-1 = 2m + b

m = -b - 3,

-1 = 2(-b - 3) + b

m = -b - 3,

-1 = -2b - 6 + b

m = -b - 3,

-1 + 6 = -2b + b

m = -b - 3,

5 = -b

m = -(-5) - 3,

b = -5

m = 2,

b = -5

▪︎ => y = 2x - 5

Answer:

I don't understand what the means

Based on the relationship of special angles, the values of x are:

1. x = 34

2. x = 9

3. x = 6

Alternate interior angles are equals and corresponding angles are also equal.

Linear pair angles are supplementary.

1. Angles j and a are linear pair angles, therefore:

3x + 15 + 2x - 5 = 180

5x + 10 = 180

5x = 180 - 10

5x = 170

x = 170/5

x = 34

2. Angles m and g are corresponding angles, therefore:

4x + 12 = 2x + 30

4x - 2x = -12 + 30

2x = 18

x = 9

3. Angles c and v are alternate interior angles, therefore:

6x + 9 = 3x + 27

6x - 3x = -9 + 27

3x = 18

x = 6

The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.

Given that:-

The number of the blue cubes are calculated as:-

The two equations will be formed by the given data in the question.

[tex]\dfrac{r}{b}=\dfrac{4}{7}[/tex]

7r = 4b

[tex]\dfrac{r+10}{b}=\dfrac{6}{7}[/tex]

7r + 70 = 6b

Solving the above equation we will get the value of b.

4b + 70 = 6b

6b - 4b = 70

2b = 70

b = 35

7r = 4b

7r = 4 x 35

r = 20

Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.
