Answer:

x = 19

Step-by-step explanation:

Question: find x such that f(x) = 2/3

Given f(x) = (-1/3) x + 7

equate the value of f(x) to be 2/3

hence,

(2/3) = (-1/3)x + 7 (multiply both sides by 3)

(3) (2/3)  = (3) (-1/3)x + (3) 7

2 = -x + 21

x = 21 - 2

x = 19

So to get the output value 2/3 we will input x = 19

A mathematical relationship from a set of inputs to a set of outputs is called a function.

An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.

Clearly, all the values of x and f(x) are satisfying it.

Now, the output is given as 2/3.

So, we can write,

[tex]\frac{2}{3} = -\frac{x}{3} + 7[/tex]

⇒  [tex]\frac{2}{3}-7 = -\frac{x}{3}[/tex]   ( changing the side of 7)

⇒ [tex]-\frac{19}{3} = - \frac{x}{3}[/tex]

⇒ x = 19

So to get the output value 2/3 we will input x = 19

Answer:

8x - 5y = - 30

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 8x - 5y = 2 into this form

Subtract 8x from both sides

- 5y = - 8x + 2 ( divide all terms by - 5 )

y = [tex]\frac{8}{5}[/tex] x - [tex]\frac{2}{5}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{8}{5}[/tex]

• Parallel lines have equal slopes, hence

y = [tex]\frac{8}{5}[/tex] x + c ← is the partial equation of the parallel line

To find c substitute (- 5, - 2) into the partial equation

- 2 = - 8 + c ⇒ c = - 2 + 8 = 6

y = [tex]\frac{8}{5}[/tex] x + 6 ← in slope- intercept form

Multiply through by 5

5y = 8x + 30 ( subtract 5y from both sides )

0 = 8x - 5y + 30 ( subtract 30 from both sides )

8x - 5y = - 30 ← in standard form

Answer:

The answer is option B. which is 2x^2 - 14 + 7.

Remember to reverse the signs.

Answer:

Option C is correct.

Step-by-step explanation:

We need to find the polynomial function in standard form with zeros at –6, 2, and 5

If a is a zero of polynomial then x-a is the factor of polynomial

So, (x+6)(x-2)(x-5) are factors of polynomial.

Multiplying these factors to find the standard polynomial function

(x+6)(x-2)(x-5)

We need to solve this:

(x+6)(x^2-5x-2x+10)

(x+6)(x^2-7x+10)

x^3-7x^2+10x+6x^2-42x+60

x^3-7x^2+6x^2+10x-42x+60

x^3-x^2-32x+60

Step-by-step explanation:

2y + 4 = 0               subtract 4 from both sides

2y = -4       divide both sides by 2

y = -2

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept → (0, b)

In the equation

y = -2

slope: m = 0

y-intercept: b = -2 → (0, -2)

y = -2 - it's a horizontal line

The answer is:

[tex]u+v=-1+2i[/tex]

To solve the problem, we just need to consider that the variable "u" and "v" represents different expressions, and then, perform the operation and add the like terms.

We must remember that the like terms are the terms that share the same variable and the same exponent.

We have that:

[tex]u=1+3i\\v=-2-i[/tex]

So, calculating we have:

[tex]u+v=(1+3i)+(-2-i)=(1-2)+(3i-i)=-1+2i[/tex]

Hence, we have that:

Final answer:

38% of eight hundred registered voters said yes, so 62% said no. By calculating 62% of 800, we find that 496 voters said no.

Explanation:

If 38% of eight hundred registered voters said yes to a measure, this means 62% said no because the total percentage must add up to 100%. To find out how many said no, we calculate 62% of 800. Here is the step-by-step calculation:

First, convert the percentage to a decimal by dividing it by 100: 62% / 100 = 0.62.

Next, multiply this decimal by the total number of voters to find the number who said no: 800 * 0.62 = 496.

Therefore, 496 voters said no to the measure.

Based on parallelogram ABCD shown below, the values of x and y include;

x = 17 units.

y = 10 units.

In Euclidean Geometry, a parallelogram is a type of quadrilateral and two-dimensional geometrical figure that has two equal and parallel opposite sides.

Generally speaking, a parallelogram has both pairs of opposite sides parallel to each other and the opposite angles (vertical angles) are congruent:

AB ║ CD

AB = CD

3x - 9 = 42

3x = 42 + 9

3x = 51

x = 51/3

x = 17 units.

Next, we would determine the value of y as follows;

4y - 3 = 37

4y = 37 + 3

4y = 40

y = 40/4

y = 10 units.

Complete Question:

Use parallelogram ABCD. What are the values of x and y?

B is the center of the circle.

Step-by-step explanation:

Given is a circle in the picture.

A is the point on the circle.

Y is another point on the circle

AY is hence the chord

B is equidistant from the circumference

B is the center of the circle.

Point B is established as the center of the circle because it is equidistant from the circumference. This property defines B as the central point from which all points on the circle are equally distant, confirming its role as the circle's center.

In the given scenario, the information provided indicates that point B is equidistant from the circumference of the circle. This property characterizes point B as the center of the circle.

To articulate this differently, since B is equidistant from any point on the circle, it serves as the central point from which all points on the circle are equally distant.

Therefore, B is unequivocally identified as the center of the circle. This conclusion is drawn from the fact that the center of a circle possesses the unique property of being equidistant from all points on its circumference.

The correct statement is that set A is a subset of set B, as they contain exactly the same elements. The statements about set B containing the number 4 and set A being infinite are false, while the empty set is a subset of every set, including B.

The correct statement regarding the sets A = {1, 2, 3} and B = {3, 2, 1} is A ⊆ B. This is because every element in set A is also in set B, regardless of the order the elements are listed. Sets are collections of distinct objects and their definition does not depend on the order of the elements. Therefore, A and B have exactly the same members, making them equal sets, and conversely, every set is a subset of itself. This can also be seen as both sets having the same cardinality, which is the number of members in a set, and for both A and B, this is 3.

As for the other statements, the number 4 is not an element of set B (4 ∈ B), the set A is not infinite since it has a finite cardinality of 3 (A is not an infinite set), and the empty set is actually a subset of every set, including B ⊂ \⊆cannot be true.

Step-by-step explanation:

A.  On one roll the possible ways to get a sum of 5 is (2,3, ) and (4, 1).

There are 36 possible outcomes from the one roll of the 2 dice.

So the probability of getting  a sum of 5 on one roll =  2/36 = 1/18.

So the probability of 5 on 4 rolls = (1/18)^4

= 1/104976.

B.  

The probability of the first 3 rolls being a 5 and the last one being not 5

= (1/18)^3 * (17/18)

= 17/104976

There are 4 ways to  pick 3 out of 4 so the required probability

=  4 * 17/104976

= 68/104976.

Final answer:

The detailed answer explains the probability of rolling specific sums with two fair dice in four rolls, covering events A and B.

Explanation:

The Probability of Rolling Sums with Two Fair Dice

For event A, the probability of getting a sum of 5 on each of the four rolls is (4/36)⁴.

For event B, the probability of getting a sum of 5 exactly three times in the four rolls is 4*(4/36)³*(32/36).

The medium pizza with a 14-inch diameter has approximately 41 square inches more area than the small pizza with a 12-inch diameter, using the formula for the area of a circle, πr², where r is the radius (half of the diameter).

The subject of this question is area comparison between two circles, which is a topic in Mathematics. The areas of the two pizzas (which we can represent as circles) can be found using the formula for the area of a circle, which is πr^2, where r is the radius (half of the diameter).

For the medium pizza, the diameter is 14 inches, so the radius is 7 inches. The area is thus π*(7)^2 = 153.94 square inches. For the small pizza, the diameter is 12 inches, so the radius is 6 inches. The area is thus π*(6)^2 = 113.10 square inches.

So, the medium pizza has 153.94 - 113.10 = 40.84 square inches more area than the small pizza. Rounded to the nearest square inch, the medium pizza has approximately 41 square inches more area than the small pizza.

Step-by-step explanation:

Hi there!

This is a Rational Function. The process of graphing it takes a lot more hard work than graphing other functions like linear, quadratic, modulus, and so on.

Here a list on how to proceed

First

1) Find the point of intersections by calculating the zeros of the function on the Numerator. In this case, we just have a 1 on top, so our graph won't intercept x-axis.

2) Calculate the vertical asymptotes by calculating the zeros of the function in the denominator, x²+4x=0 S=(0,-4) on green on the graph below.

3) Construct the table of values for x, and y

4) Trace the graph

By analyzing the asymptotes on the graph, we conclude that the correct option is C.

To do it, we need to see at which x-values we have asymptotes. These are the values of x where the denominator becomes equal to zero.

Here we can see that we have asymptotes at:

x = 0 and x = -4

Then the denominator must be a polynomial with roots at x = 0 and x = -4, this is written as:

(x - 0)*(x - (-4)) = x*(x + 4)

So the rational function is something like:

[tex]f(x) = \frac{1}{x*(x + 4)}[/tex]

So the correct option is C.

A.  The angle measures are 30°, 60°, and 90°.

on edge

Step-by-step explanation:

If the question provides the angles of a triangle as 30°, 60°, and 90°, or 45°, 45°, and 90°, we are dealing with a right triangle. Depending on the measures of the angles, the triangle can be classified as either a 30-60-90 triangle or a 45-45-90 isosceles right triangle. Without sufficient information, the exact measures of the angles cannot be determined.

When considering a triangle with angle measures provided as options, we recall the fundamental property that the sum of internal angles in any triangle is 180 degrees. The question presents three possible sets of angle measures:

Both of the first two options include a 90° angle, indicating that we are dealing with a right triangle. Right triangles have specific properties and can be classified as either 30-60-90 or 45-45-90 triangles, depending on the measures of the other two angles. A 30-60-90 triangle has angles in the ratio of 1:2:√3, and a 45-45-90 triangle, also called an isosceles right triangle, has two angles of 45° each. The third option implies insufficient information to determine the exact measures of all angles.
