The equation of the line -4x + y = 10 has -5/2 and 10 as its x- and y-intercept, respectively.

The equation of a line is an equation containing variable(s) and constant(s) and can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The x-intercept of a line is the value of x when y = 0 while the y-intercept of a line is the value of y when x = 0.

For an equation written in standard form ax + by = c, the x- and y-intercept is as follows:

x-intercept = c/a

y-intercept = c/b

If the equation of the line is -4x + y = 10, then its x- and y-intercept is as follows:

x-intercept = c/a = 10/-4 = -5/2

y-intercept = c/b = 10/1 = 10

The relationship between the number x of days and the total cost represent as piecewise function.

f(x) = -x < 0

      = x if x ≥ 0

The bike store charges $20 for the first day and $15 for each additional day. The relationship between the number x of days and the total cost represent as:

f(x) = 20 , if 0 < x ≤ 1

      = 35,  if 1 < x ≤ 2

      = 50,  if 2 < x ≤ 3

      = 65,  if 3 < x ≤ 4

The absolute value function f(x) = |x| can be written as a piecewise function.

f(x) = -x < 0

      = x if x ≥ 0

Piecewise functions: A piecewise function is made up of two or more functions, each defined on a specific domain. Piecewise functions follow the following format:

f(x)    ⇒ -x,   x < 0

               ⇒  0,  x = 0

                ⇒ x,  x > 0

The piecewise function above is the absolute value function. As you can see, piecewise functions include:

A curly bracket to indicate that the function is comprised of more than one subfunction

The subfunctions that make up the piecewise function

The subdomains corresponding to each subfunction

The domains of the subfunctions cannot overlap, but one function can end where another starts. If different functions were part of the same domain, the piecewise function would not be a function anymore!

To graph a piecewise function, graph each subfunction at the indicated domain. Be wary of the inequality symbols (< , ≤ , > , ≥) and whether they include or exclude the end of the subdomain. If they include the domain, draw a point and fill it in. If they exclude the domain, draw a point but do not fill it in.

Answer:

68%

Step-by-step explanation:

the mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

calculate the sum for both classes

class 1

[tex]\frac{sum}{20}[/tex] = 64 ( multiply both sides by 20 )

sum = 1280

class 2

[tex]\frac{sum}{10}[/tex] = 76 ( multiply both sides by 10 )

sum = 760

combine the 2 sums and divide by count of both classes for overall mean

overall mean = [tex]\frac{1280+760}{30}[/tex] = [tex]\frac{2040}{30}[/tex] = 68%

The first term of the given sequence is a(1) = 128

The formula for the nth term of a geometric sequence is:

a(n) = a(1) . rⁿ⁻¹

In the above formula, a(1) refers to the first term while r refers to the common ratio.

Information from the problem.

a(9) = 1/2 and a(12) = 1/16

Substitute n = 9 into the formula, we get:

a(9) = a(1) . r⁸

1/2  = a(1) .  r⁸

Substitute n = 12 into the formula, we get:

a(12) = a(1) . r¹¹

1/16  = a(1) .  r¹¹

Divide a(12) by a(9):

1/16 : 1/2 = ( a(1) .  r¹¹ ) : (a(1) .  r⁸ )  

Since a(1) terms are cancelled out, we have:

2 : 16 = r¹¹ :  r⁸

1/8 = r³

r = 1/2

Substitute r = 1/2 into a(9) :

a(9) = a(1) . r⁸

1/2 = a(1) . (1/2)⁸

a(1) = 1/2 : (1/2)⁸ = (1/2)¹⁻⁸

       = (1/2)⁻⁷ = 2⁷

The constant of proportionality for the relationship of millimeters of rainwater to time in hours is 48 millimeter/hour.

Given that the measuring tool captures rain falling at a constant.The table shows the height of rainwater in the measuring tool and the number of minutes it rains as shown in attached image.

A ratio is a mathematical comparison between two numbers. In proportion, if two given sets of numbers increase or decrease by the same ratio then the given ratios are said to be proportional.

Now we will calculate the proportion by using the formula

Ratio=(r₂-r₁)/(t₂-t₁)

Here, r₁=4, r₂=8, t₁=5, t₂=10

So, r₂-r₁=8-4=4 and

t₂-t₁=10-5=5

Now, we will convert the time from min to hour by dividing it with 60, we get

t₂-t₁=5/60

Substitute this value in above equation, we get

Ratio=4/(5/60)

Ratio=(4×60)/5

Ratio=4×12

Ratio=48 mm/hr

Hence, the constant of proportionality for the relationship of millimeters of rainwater to time in hours by using the given table is 48 mm/hr.

According to the Alternate Exterior Angles Theorem, when two parallel lines are severed by a transversal, the resultant alternate exterior angles are congruent if and only if the transversal is itself parallel to the two parallel lines.

So, in the figure below, if k ∥ l then

∠1 ≅ ∠7 and ∠4 ≅ ∠6.

Proof.

Since k ∥ l by the Corresponding Angles Postulate,

∠1 ≅ ∠5.

Also, by the Vertical Angles Theorem,

∠5 ≅ ∠7

Then, by the Transitive Property of Congruence,

∠1 ≅ ∠7

You may use the same strategy to demonstrate that ∠4 and ∠6 are equivalent to establish that they are congruent.

It should also be noted that the opposite of this theorem is true; more specifically, if two lines, k, and l, are sliced by a transversal in such a way that the alternative exterior angles are congruent, then k∥l.

   The equation that defines the parabola with vertex at the origin and focus at (0, -4) is

y = -x²/16

We define what a parabola is

 The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.

  The canonical equation of a parabola is given by

(x - h)² = 4p(y - k)

   The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.

Since the vertex and the focal axis are on the same axis, we analyze that:

v = (0, 0)

f = (0, -4) This means that the focus is on the negative part of the y-axis, the form of the equation of this parabola is y = x²

(x - 0)² = 4p(y - 0)

Focus:

f = (0, 0 + p)

(x - 0)² = 4*-4(y - 0)

The measure of the smallest angle is 31°, the middle angle is 67°, and the measure of the largest angle is 82°.

A triangle is a plane shape with three edges and three vertices. All triangles have three internal angles, and the addition or sum of these angles gives 180°. In the question above, the three angles of the triangle are not given, though, we are given some clues as to how we can find them:

        Not much is said about the first angle, so we'll call it angle a.

        We are told that the second angle (angle b) is 5 more than twice

        angle a. The '5 more' means '5+' twice the value of angle a. Thus;

                             angle b = 5 + 2a

        The third angle, angle c is 11 less than 3 times the measure of angle

        a, meaning that angle c is 3 times angle a minus 11, thus;

                            angle c = 3a - 11

The addition of angle a, angle b and angle c gives 180°, hence:

                    a + 5 + 2a + 3a - 11 = 180°

                    a + 2a + 3a + 5 - 11 = 180°

                    6a -6 = 180

                    6a = 180 + 6

                    6a = 186

Dividing both sides by 6,

                      a = 31°

Now that we know the value of angle a, angle b will be

                        5 + 2(31) = 67°

and angle c is  

                        3(31) - 11 = 82°

Hence, the measure of the smallest angle, angle a is 31°, the middle angle, angle b is 67°, and the largest angle, angle c is 82°.

0.25 is the probability a bean bag lands closer to the center of the circle than to the edge of the circle.

What is the probability in simple terms?

Let the radius of the circle be r.

Now the distsnce of the edge of the circle from the center is r units.

Now for any point lying in the circle, the sum of the distance of that point

from the center and from the nearest edge of the circle is r.

Thus, the bag will land closer to the circle if it lies within r/2 distance from the center.

Now, the area of the inner circle with radius r/2 is =  [tex]\pi (\frac{r}{2})^{2} = \pi \frac{r^{2} }{4}[/tex]

The area of the actual circle = πr²

Thus, the bean bag will land closer to the center if it lies within the inner circle of area = π r²/4

Hence, the required probability = [tex]\pi r^{2} /4/ \pi r^{2}[/tex] = 1/4 = 0.25

The steps that could be part of the process of algebraically solving the system of equations, y + 5x = x2 + 10 and y = 4x – 10 are

An algebraic equation is a mathematical statement that sets two expressions equal using variables, coefficients, and constants.

Algebraic equations are represented by the equal symbol (=).

y + 5x = x² + 10 and y = 4x – 10

Substitute y = 4x - 10:

4x – 10  + 5x = x² + 10

4x - 10 = x² – 5x + 10

Add 10 to both sides:

4x - 10 + 10 = x² - 5x + 20

4x = x² - 5x + 20

Subtract 4x from both sides:

4x - 4x = x² - 5x  - 4x + 20

0 = x² - 9x + 20

Solving, if x = 4:

x² - 9x + 20 = 0

4² - 9 (4) + 20 = 0

16 - 36 + 20 = 0

Answer:

y=61°

Step-by-step explanation:

(y-8°)+(y+15°)+(y-10°)=180°

y-8°+y+15°+y-10°=180°

3y-3°=180°

3y=180°+3°

3y=183°

3y÷3=183°÷3

y=61°

The value of y from the given triangle can be calculated using the angle sum property as 61.

Given that:

A triangle has three angles given.

The measures of the angles are y - 8°, y - 10°, and y + 15°.

The angle sum property of triangles is defined as the property which states that the sum of the angles of the triangle is 180°.

Equating the angle measures:

y - 8 + y - 10 + y + 15 = 180

Add the like terms together.

3y - 3 = 180

Take 3 as common.

3(y - 1) = 180

Divide both sides of the equation by 3.

y - 1 = 60

Add 1 on both sides.

y = 61
