find the rate of change /slope between its ordered pairs
(-5,13) and (1,1)
(-5,14)and (12,-21)
(1,1)and(12,-21)​

Answers

Answer 1

Answer:

1.) -2

2.) -2

3.) -3

Step-by-step explanation:

Since we can't make a graph, we can make a table

(-5,13) and (1,1)

x       y

-5      13

1        1

From 13 to 1, you subtract 12 ( y-section)

From -5 to 1, you add 6 (x-section)

Now we can do y/x

y/x = 12/6 = -2

The slope for this first one is (-2).

(-5,14) and (12,-21)

x           y

-5          14

12         -21

From 14 to -21, you subtract 34

From -5 to 12, you add 17

Now we can do y/x

y/x = -34/17 = -2

The slope for this second one is (-2)

(1,1 )and (12,-21)​

x        y

1        12

12     -21

From 12 to 21, you subtract 33

From 1 to 12, you add 11

Now we can do y/x

y/x = -33/11 = -3

The slope for this third one is (-3)

Hope this helped!

Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

The length of the sand dune is 88 feet.

What is the Pythagorean theorem?

Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

We have,

Hypotenuse = 137 feet

One side length:

Horizontal length = 105 feet

Another side length = side = length of the sand dune.

Using the Pythagorean theorem we get,

137² = side² + 105²

18769 = side² + 11025

side² = 7744

side = √7744

side = 88 feet

Thus,

The length of the sand dune is 88 feet.

Three (3) consecutive integers is such that the largest is x. Write an expression
for the smallest.

Answers

Answer:

Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)

Step-by-step explanation:

Five times the smallest means 5x

Sum of the largest and five times the smallest means x+2+5x

This sum is -244 means x+2+5x=-244

Solve this equation

x+2+5x=-244

6x+2=-244

6x=-244-2

6x=-246

x=-41

So, smallest number is -41, second is -40 and largest is -39

You're answer is -39+5(-41)=244

how do you find the axis of symmetry?​

Answers

Answer:

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

Step-by-step explanation:

Answer:

x=-b/2a

Step-by-step explanation:

axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).

The expression to find vertex is -b/2a

Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

Convert each radian measure into degrees.

Answers

Answer:

[tex]\boxed {\boxed {\sf 480\textdegree}}[/tex]

Step-by-step explanation:

First, remember that π radians is equal to 180 degrees. Therefore, to convert from radians to degrees, multiply by 180/π.

The radian measure given is 8π/3

[tex]\frac {8 \pi}{3} * \frac{180}{\pi}[/tex]

Multiply the fractions. Multiply across the numerator, then across the denominator.

[tex]\frac{8 \pi *180}{3 * \pi}[/tex]

The pi in the numerator and denominator will cancel out.

[tex]\frac{8 *180}{3 }[/tex]

Multiply.

The radian measure 8π/3 is equal to 480 degrees.

A plumbing company charges a $95 fee for each job, plus $65 foreach hour that the job lasts. The expression 65h + 95can be used to calculate the cost of a job in dollars, where hrepresents the number of hours the job takes to complete. Part A.What is the cost of a job that lasts 1.5 hours?

Answers

Answer:

the answer would be 160H

The cost of a job that lasts 1.5 hours is  $ 192.5

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The charge of each job by the plumbing company = $ 95

The charge on each hour for each job = $ 65

The equation for the cost of a job is = 65h + 95

where h is the number of hours for the job

Now , to calculate the cost of job that lasts 1.5 hours ,

substitute the value of h as 1.5

And , the equation becomes

= 65h + 95

= 65 ( 1.5 ) + 95

= 97.5 + 95

= $ 192.5

Hence , the cost of a job that lasts 1.5 hours is  $ 192.5

A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.​

Answers

Answer:  bigger number is 48 and smaller number is 36

Step-by-step explanation:

Answer:

The smaller number  ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48

Step-by-step explanation:

Let the larger number be = xLet the smaller number be = y

As the larger number is twelve more  than a smaller, so

x = y + 12

As the sum of larger and smaller numbers is 84, so

x + y = 84

now substituting x = y + 12 in th equation x + y = 84

x + y = 84

(y + 12) + y = 84

2y + 12 = 84

subtract 12 from both sides

2y + 12 - 12 = 84 - 12

2y = 72

divide both sides by 2

2y/2 = 72/2

y = 36

Thus,

The smaller number  ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48
