-2

Step-by-step explanation:

To find slope, we need to use the formula

[tex]\frac{y2-y1}{x2-x1}[/tex]

Substituting your coordinates (-1,8) and (5,-4) , we get -2 as a result.

Answer:

slope = - 2

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (5, - 4 )

m = [tex]\frac{-4-8}{5-(-1)}[/tex] = [tex]\frac{-12}{5+1}[/tex] = [tex]\frac{-12}{6}[/tex] = - 2

Answer:

ABCDE is a regular pentagon with congruent diagonals BE and BD. a) Justify AABE = ACBD with a test for congruent triangles. b) Name a pair of congruent quadrilaterals.

The present age of Madison is 1027 years and that of his mother is 3080 years (rounded off to nearest whole numbers), solved using the linear equation in one variable: (x + 614) + (3x + 614) = 5334, where x represents the present age of Madison.

Linear equations in one variable are the linear relationship between two algebraic expressions not involving more than one variable throughout the equation.

In the question, we are informed that the present age of Maison's mother is 3 times that of Madison. After 614 years, the sum of their age will be 5334 years.

We are asked to determine their present ages.

We assume the present age of Madison to be x years.

Therefore, the present age of Madison's mother = 3x years {3 times that of Madison}.

Now, after 614 years, both of their ages will increase by 614 years.

Therefore, age of Madison after 614 years = x + 614 {Present + 614}.

Age of Madison's mother = 3x + 614 {Present + 614}.

We are given that after 614 years, the sum of their ages will be 5334.

This can be represented by the linear equation in one variable:

(x + 614) + (3x + 614) = 5334

This linear equation in one variable can be simplified and solved in the following way:

or, 4x + 1228 = 5334 {Simplifying},

or, 4x + 1228 - 1228 = 5334 - 1228 {Subtracting 1228 from both sides}

or, 4x = 4106 {Simplifying}

or, 4x/4 = 4106/4 {Dividing both sides by 4},

or, x = 1026.5 {Simplifying}.

Therefore, the present age of Madison = x = 1026.5 = 1027 years (nearest whole number).

The present age of Madison's mother = 3x = 3*1026.5 = 3079.5 = 3080 years (nearest whole number).

By using the given distances and directions, we have;

Part A: 1083.5 feet

Part B: 1921.37 feet

Part C: 58.05°

The distance between David and Lacey = 2000 feet

David's angle to the boat = 70°

Lacey's angle to the boat = 32°

Part A

The distance of the boat from David is found as follows;

Imaginary lines drawn from the boat to David and then to Lacey form a triangle.

In the triangle, let A = 70°

B = 32°

Therefore by the sum of angles in a triangle, we have;

C = 180° - (70° + 32°) = 78°

By using sine rule we have;

[tex] \frac{a}{sin(A)} = \frac{b}{sin( B )} = \frac{c}{sin(C)}[/tex]

David's distance from the boat, b, is therefore;

[tex] \frac{b}{sin( 32 )} = \frac{2000}{sin(78)}[/tex]

The angle subtended by the coastline, C, is therefore;

[tex] b = \frac{2000}{sin(78)} \times sin( 32 ) = 1083.5 [/tex]

Part B

The distance between the boat and Lacey is found as follows;

[tex] \mathbf{ \frac{a}{sin( 70)} }= \frac{2000}{sin(78)}[/tex]

[tex] a = \frac{2000}{sin(78)} \times sin( 70 ) = 1921.37 [/tex]

Part C

When b = 1200 feet, we have;

Finding the vertical distance of the boat from the coastline, we have;

1083.5 × sin(70) = 1018.17

We have;

[tex] \frac{1200}{sin(90)} = \frac{1018.17}{sin( B' )} [/tex]

[tex] {sin( B' )} = \frac{sin(90)}{1200} \times 1018.17 [/tex]

y = 90°

Step-by-step explanation:

Answer:

x = 39°

y = 92°

Step-by-step explanation:

x = 39° because alternate (or z) angles are equal.

x = 92° because all angles in a triangle add up to 180°.

so

49+39=88

angles on a straight line are equal to 180°

Step-by-step explanation:

From the table, we can deduct that y = 1.3x, which means it is a linear function. A linear function, when graphed, is a straight line.

Step-by-step explanation:

arithmetic operations with functions just means to do these operations with the function expressions. and the result is the resulting function.

so,

(f - g)(x) = f(x) - g(x) = (2x² + 3) - (x² - 7) =

The missing values of x² column of the table are; 9 and 16 respectively and the value of ΣX² is; 47.

If follows from the table that the three columns of the table record values x, y and x².

On this note, if fill that the first missing value in which case, x = 3 and y = 2 is; 3² = 9. And in the second case where, x = 4 and y = 3 is; 4² = 16.

Step-by-step explanation:

The line DF is equivalent in length to the blue line,

Solve:

x + 14 = 4x + 2

subtract 14 from both sided to get x alone,

x + 14 - 14 = 4x + 2 - 14

x = 4x - 12

subtract 4x from both sided,

x - 4x = 4x - 4x - 12

-3x = -12
