3. Emma purchased a bicycle at a garage sale for $56. She later sold the bicycle online for $85.What was the percent increase of the price of the bicycle?

Answer:

green line:

rise= -6

run= 3

rise/run = slope

therofore the slope = -6/3 = -2

blue line:

rise=3

run=6

rise/run = slope

therofore the slope = 3/6 = 1/2

Answer:

- 2 and [tex]\frac{1}{2}[/tex]

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 ) = (- 3, 5) and (x₂, y₂ ) = (0, - 1) ← 2 points on the green line

m = [tex]\frac{-1-5}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2

Repeat with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the blue line

m = [tex]\frac{0+3}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Since the product of the slopes = - 2 × [tex]\frac{1}{2}[/tex] = - 1

Then the lines are perpendicular

Answer:

x = 24

y = 15

Step-by-step explanation:

Since, angles (3x - 29)° and (6x - 7)° is a pair of consecutive exterior angles,

Therefore, (3x - 29)° + (6x - 7)° = 180°

9x - 36 = 180

9x = 180 + 36

x = [tex]\frac{216}{9}[/tex]

x = 24

Therefore, (3x - 29)° = 3(24) - 29

                                  = 43°

Since, angles (3x - 29) and (8y + 17) is a linear pair.

(3x - 29)° + (8y + 17)° = 180°

43° + (8y + 17)° = 180°

8y + 60 = 180

8y = 120

y = 15

Therefore, x = 24 and y = 15 will be the answer.

Answer:

Step-by-step explanation:

Answer:In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.

Step-by-step explanation:

The slopes of two parallel lines are always equal.

The slope of a line can be calculated by taking the tangent ratio of the angle formed by it with the x axis.

The angle between two parallel lines is zero.

It implies that they form same angle with the x-axis.

Since, the slope of a line is define as the tangent of the angle made by it with x axis.

The slopes of the parallel lines will be equal.

Suppose the slopes of two parallel lines are m₁ and m₂.

Then, it can be written as m₁ = m₂.

Hence, the relationship between the slopes of two parallel lines can be written as m₁ = m₂.

If this is wrong I'm so sorry but that's what I think it is.

The required total cost for Chole and Charlie is y = 7 + 2t.

Given that,

Chloe and Charlie are taking a trip to the pet store to buy some things for their new puppy. They know that they need a bag of food that costs $7, and they also want to buy some new toys for the puppy. They find a bargain barrel containing toys that cost $2 each.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the total cost be y,
According to the given condition,
Total cost = 7 + 2t
where 2t is the total cost of the toys purchased.
y = 7 + 2t

Thus, the required total cost for Chole and Charlie is y = 7 + 2t.

Answer:

not factorable

Step-by-step explanation:

To factor a trinomial of the type x^2 + ax + b, you need to find two numbers that add to a and multiply to b.

You have 1x^2 + 9x + 2.

In this case, a = 9 and b = 2.

There are no two integers whose sum is 9 and whose product is 2, so this trinomial is not factorable.

Answer:

The rocket will reach the maximum height after 8.34 seconds.

Step-by-step explanation:

We need to take the derivative of the function and set it to 0.

[tex]y' = -32x + 267 = 0\\32x = 267\\x = 8.34[/tex]

The maximum height of the rocket at x = 8.34375 will be 1,220.89.

For the maximum value of the function if f''(x) < 0 and for the minimum value of the function if f''(x) > 0.

The maximum and minimum value of the function is at f'(x) = 0.

A rocket is sent off from a pinnacle. The level of the rocket, y in feet, is connected with the time after send-off, x like a flash, by the given condition.

The equation is given below.

y = -16x² + 267x + 107

Differentiate the function and put it zero to get the value of time that is 'x' will be given as,

y' = 0

(d/dx)(-16x² + 267x + 107) = 0

-32x + 267 = 0

32x = 267

x = 8.34375

Then the maximum height of the rocket at x = 8.34375 will be given as,

y = -16(8.34375)² + 267(8.34375) + 107

y = -1,113.89 + 2,227.78 + 107

y = 1,220.89

The maximum height of the rocket at x = 8.34375 will be 1,220.89.
