=========================================================

Explanation:

Vertical angles are always congruent.

Set the two expressions equal to one another and solve for x.

6x - 6 = 3(x+6)

6x - 6 = 3x + 18

6x - 3x = 18 + 6

3x = 24

x = 24/3

x = 8

Then use this x value to find each angle

Both angles are 42 degrees each to confirm the answer.

Answer:

First option A

Step-by-step explanation:

Solved this by looking at the points of the graph from left to right. (-3,-2) is the first being the furthest left then so on.

The solution to given equation 2x / 3 - 1/2 = 2x + 5/6 is x = -1

In this question, we have been given an equation.

2x / 3 - 1/2 = 2x + 5/6

We need to find the solution of given equation.

⇒ 2x / 3 - 1/2 = 2x + 5/6

⇒ (4x - 3)/6 = (12x + 5)/6

⇒ 4x - 3 = 12x + 5

⇒ 4x - 12x = 5 + 3

⇒ -8x = 8

⇒ x = -1

We need to check above solution.

so, substitute x = -1 in LHS of given equation.

LHS

= 2(-1) / 3 - 1/2

= -2/3 - 1/2

= -(2/3 + 1/2)

= -[(4 + 3)/6]

= -7/6

Now, substitute x = -1 in RHS of given equation.

RHS

= 2(-1) + 5/6

= -2 + 5/6

= (-12 + 5)/6

= -7/6

For x = -1, LHS = RHS

Therefore, the solution to given equation 2x / 3 - 1/2 = 2x + 5/6 is x = -1

The probability for the arrow that land in the number 3 is 1/8.

Probability:

Basically, the word probability means the possibility of occurring the required event.

Given,

The spinner is divided into 8 equal sections.

Here we need to find if the arrow lands on a number, what is the probability that it will land on 3.

Let us consider that the spinner has 8 equal-sized sections numbered 1 to 8.

Since the sections have equal size, each section is equally probable.

The probability of falling on each section is therefore 1/8.

We know that, in the 8 sections,

There is only one 3 in this list.

So, the possibility of the event = 1

Hence, probability is

=> 1/8

Therefore, the probability for the arrow that land in the number 3 is 1/8.

Answer:

Let r be the number of rides and g be the number of games.

2.50g + 4.00r = 52.50

r = 2g

The equations are 2.5g +4r = 52.5 and g=2r.

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. LHS = RHS is a common mathematical formula.

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:

Cost of game = $2.50

Cost of ride = $4

let g be the number of games

and, let r be the number of rides taken

total they played = $52.50

So, the equation can be

2.5g +4r = 52.5

and,  number of rides she went on is twice the number of games she played.

So, g = 2r

Hence, The equations are 2.5g +4r = 52.5 and g=2r.

The restriction will be f-¹(x) range: y ≥ 0

Domain of a function:

The domain of a function refers to the set of all possible inputs for the function. For example, we get that the domain of f(x) = x² is all real numbers, and the domain of g (x) = 1 / x is all real numbers except for x = 0( as it will make the function indefinite.) Some special functions can also be defined whose domain are limited.

Range of a function:

The range of a function refers to the complete set of all possible resulting values of the dependent variable, after we have substituted the domain.

So, the restriction will be f-¹(x) range: y ≥ 0 as x² will always be positive.

Therefore, the restriction will be f-¹(x) range: y ≥ 0.

Step-by-step explanation:

Using the definition of slope, the points (3 , -5), (-3 , 3), and (0 , 2) are not collinear.

Three or more points are said to be collinear if they lie on a single straight line.

To determine whether the given points are collinear, use the definition of slope. The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.

m = (y2 - y1)/(x2 - x1)

Getting the slope of each pair of points:

(3 , -5) and (-3 , 3)

m = (y2 - y1)/(x2 - x1)

m = (3 - -5)/(-3 - 3)

m = 8/-6

m = -4/3

(-3 , 3) and (0 , 2)

m = (y2 - y1)/(x2 - x1)

m = (2 - 3)/(0 - -3)

m = -1/3

(3 , -5) and (0 , 2)

m = (y2 - y1)/(x2 - x1)

m = (2 - -5)/(0 - 3)

m = 7/-3

m = -7/3

Since collinear points lies on the same line, the slope of any pair of points should be the same. Since the slopes of each pair of points is not equal with each other, then they are not collinear.

The ratio of the volume of the hemispherical tank to its surface area is, V/A = 2r/9.

A three-dimensional object's total surface area exists the whole area of all of its external surfaces.

Let r be the radius of the circle and h be the height

To find volume of the hemispherical tank and its surface area.

Here,

TSA = Total Surface Area

CSA = Curved Surface Area

Volume of a hemisphere (V) = (2/3) πr³

TSA of the hemispherical tank(A) = CSA of the tank + CSA of the base.

TSA(A)  = 2πr² + πr² = 3πr²

The ratio of the volume of the hemispherical tank to its surface area is,

V/A = (2/3)πr³ / 3πr²

V/A = 2r/9

Therefore, the ratio of the volume of the hemispherical tank to its surface area is, V/A = 2r/9.

Answer:

x = 2, x = -6

Step-by-step explanation:

Given quadratic function in vertex form:

[tex]f(x)=(x+2)^2-16[/tex]

The zeros of a function occur when f(x) = 0:

[tex]\implies (x + 2)^2 - 16 = 0[/tex]

Add 16 to both sides:

[tex]\implies (x + 2)^2 - 16+16 = 0+16[/tex]

[tex]\implies (x + 2)^2 =16[/tex]

Square root both sides:

[tex]\implies \sqrt{ (x + 2)^2} =\sqrt{16}[/tex]

[tex]\implies x+2= \pm 4[/tex]

Subtract 2 from both sides:

[tex]\implies x+2-2= -2 \pm 4[/tex]

[tex]\implies x= -2 \pm 4[/tex]

Therefore:

[tex]\implies x=-2+4=2[/tex]

Total points needed = 167

Let 'x' be the number of visits.

Total points earned for x number of visits: 10.5x.

Thus, the equation according to statement;

20 + (10.5 × x) = 167

10.5x = 167 - 20

10.5x = 147
