Answer: To graph y = x is simple, it is a line that intercepts at 0, and goes up by 1/1, or 1 (rate of change)

Step-by-step explanation:

1. For C, it's simple, it is y = -x, since the negative reciprocal slope is usually perpendicular to the original number (if not able to convert to fractions, like 1, it's just the same whole number, but a negative).

2. For the "Rotate your slope triangle 90 degrees"; seems simple, which I think you should do a reciprocal of the number, and make it a negative, for ie. 3 is a slope, when changed, it becomes -1/3. so the new slope is a negative reciprocal.

The equation of the absolute value function is y = -|x - 3| + 6

The given parameters are

Vertex = (3, 6)

Crosses the x-axis at (-3,0) and (9,0)

An absolute value equation is represented as

y = a|x - h| + k

Where

Vertex = (h, k)

So, we have

y = a|x - 3| + 6

At (-3, 0), we have

0 = a|-3 - 3| + 6

This gives

0 = a|-6| + 6

So, we have

0 = 6a + 6

Solve for a

a = -1

Substitute a = -1 in y = a|x - 3| + 6

y = -|x - 3| + 6

Hence, the equation of the absolute value function is y = -|x - 3| + 6

x =20°

Step-by-step explanation:

since both sides are equal

3x° = (5x-40°)

3x = 5x - 40°

CLT( collect like terms)

40°= 5x - 3x

40° = 2x

40°/2= 2x/2

20° = x

therefore x =20°

The new depth of the orange juice is now 4cm

From the question, we are to calculate the depth of the orange juice after Jane turns the carton

First, we will determine the volume of orange juice in the carton.

The volume of orange juice in the carton = 10 cm × 6 cm × 8cm

Volume of orange juice in the carton = 480 cm³

Now, we will determine the depth of the orange juice when the carton stands on the shaded face

If carton stands on the shaded face,

The length becomes 20 cm

and

The width becomes 6 cm

Let the new depth of the orange juice be h

Then,

We can write that

480 = 20 × 6 × h

480 = 120 × h

h = 480/120

h = 4 cm

Hence, the new depth of the orange juice is now 4cm

The domain of a function is the set that contains all possible input values for the function. In a graph, it is given by the values of x.

In this problem, the function is defined between x = -4 and x = 4, hence the domain is [-4,4].

The zeros are the values of x for which f(x) = 0, that is, when it crosses the x-axis.

Hence, for this problem, the zero is at (0,0).

The function is positive when it is above the x-axis, and negative when it is below, hence:

A)- The distribution is skewed left.

B)- The histogram has one​ mode, at 74 to 76 years.

The distribution of numerical data is roughly shown by a histogram. Karl Pearson is credited with coining the phrase. The first stage in creating a histogram is to "bin" (or "bucket") the range of values, or split it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as a series of discrete intervals that don't overlap. Histograms provide a general idea of the density of the underlying distribution of the data, and are frequently used for density estimation: estimating the probability density function of the underlying variable. The bins (intervals) must be adjacent and are frequently (but not always) of equal size.

Using linear equations, A rental car company charges prices based on the number of days you rent the car will charge  $185 if you rent the car for 7 days.

A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Let us consider the number of days = x

The equation when number of days(x) <= 4,

⇒ $50 + $25x1 = y1

If the car is rented for more than 4 days, (x>4)

⇒ $45 + $20x2 = y2

Now, we are to calculate the rent for 7 days,

which equals,

y2 = $45 + $20x2

for x2 = 7,

y2 = $45 + $20 × 7

⇒ 45 + 140

⇒ $185

The difference of depths between them, and which trench is deeper is (a) 2 km, and the Mariana Trench is deeper

What is the difference of depths between them, and which trench is deeper?

The given parameters are:

Mariana Trench = 11 km

Japan Trench = 9 km

The Mariana Trench is deeper because 11 is greater than 9

The difference between the depth is

Difference = 11 km - 9 km

Difference = 2 km

Hence, the difference of depths between them, and which trench is deeper is (a) 2 km, and the Mariana Trench is deeper

The number of wins is 68 ad losses is 26.

Let the number of losses = l

Therefore, the number of wins will be: = (2 × l) + 16 = 2l + 16

Total games = 94

Therefore we will add the equation

l + 16 + 2l = 94

3l + 16 = 94

3l = 94 - 16

3l = 78

l = 78/3

l = 26

Losses = 26

It is square-shaped as it is 4-straight sides with equal length, and every interior angle is right angle.

A right angle is defined as an angle in geometry and trigonometry that is exactly 90 degrees, or pi /2 radians, or one-quarter turn. The adjacent angles are right angles if a ray is positioned so that its terminus is on a line and they are equal. An interior angle is a shape's internal angle. The closed shape with sides and vertices is a polygon. All of the inner angles of a regular polygon are equal to one another. For instance, a square has interior angles that are all exactly right angles, or 90 degrees. The right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection. The symbol is used to indicate a right angle.

The quadratic equation x² - 10x + 9 = 0. = 0 by completing the square, which of the following equations is a step in the process

(x – 10)2 = 34

(x – 10)2 = 16

(x – 5)2 = 34

(x – 5)2 = 16

Given that

To find

So, according to the question

We have

We have to solve that quadratic equation by completing square method.

So, we know that

In Completing square method, we have to convert this quadratic equation in square form.

So,

                  x² - 10x + 9 = 0.

Now, by multiplying both sides by the square of the x-coefficient, we get

                  x² - 10x + 9 + (-10/2)² = 0 + (-10/2)²

                       x² - 10x + 9 + (-5)² = 0 + (-5)²

Now, simplify it

                       x² - 10x + 9 + (-5)² = 0 + (-5)²

                          x² - 10x + 9 + 5² = 0 + 5²

                          x² - 2×5×x + 5² + 9 = 0 + 5²

∵ (a - b)² = a² - 2ab + b²

∴ (x - 5)² = x² - 10x + 5²

                                   (x - 5)² + 9 = 25   [since (x² - 10x + 5² = (x - 5)²]

                                        (x - 5)²  = 25 - 9
