The number of visits Jackson must make to earn a free movie ticket is 14 and the equation is 8.5x + 35  = 154.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Jackson has a points card for a movie theater. He receives 35 reward points just for signing up. He earns 8.5 points for each visit to the movie theater.

Let x be the number of visits Jackson must make to earn a free movie ticket.​

8.5x + 35  = 154

8.5x = 154 - 35

8.5x = 119

x = 119/8.5

x = 14

Thus, the number of visits Jackson must make to earn a free movie ticket is 14 and the equation is 8.5x + 35  = 154.

The x coordinate of the solution to the system is 4

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

x + 2y = 6

5x - 4y = 16

Next, we plot the graph of x + 2y = 6  and 5x - 4y = 16 (see attachment)

From the attached graph, the point of intersection is

(x, y) = (4, 1)

Remove the y coordinate

Step-by-step explanation:

the total charge is £195.

we have 36 students. each paying £4.25.

we have 3 parents. each paying 2×£4.25 = £8.50

we have 3 teachers. each paying £0.

a.

the payments are

36×4.25 + 3×8.50 = 153 + 25.5 = £178.50

that is clearly below the total charge of £195.

there is a deficit of 195 - 178.5 = £16.50

b.

3 teachers.

so, each should pay

16.5 / 3 = £5.50

c.

8 students drop out.

that means

8× 4.25 = £34.00 are not paid.

we have now

28 students

3 parents

3 teachers

on the bus.

these are 34 persons.

34 / 34 = £1.00

they each would have to pay £1.00 as extra payment.

Given the radius and height, the volume of the cone to the nearest hundredth is 25.12 in³.

Option b)25.12 in³ is the correct answer.

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The volume of a cone is expressed as;

V = (1/3)πr²h

Given the data in the question;

Plug the given values into the volume formula above and simplify.

V = (1/3)πr²h

V = (1/3) × 3.14 × (2in)² × 6in

V = (1/3) × 3.14 × 2in² × 6in

V = (1/3) × 3.14 × 4in² × 6in

Measures of each angle are as follows:

4.     ∠BXC = 20°

5.     ∠FXE = 85°

6.     ∠GXD = 75°

7.     ∠BXF = 75°

Step-by-step explanation:

#4
 ∠BXC is opposite ∠EXD and so it is the same as ∠EXD = 20°

#5
∠FXE is opposite ∠CXG and so it is the same as ∠CXG = 85°

#6
Angles  ∠CXG, ∠GXD and ∠EXD line on a straight line so the sum of these angles must be 180°
∴ m∠CXG + m∠GXD + m∠EXD = 180°

Substituting known values for ∠CXG and ∠EXD we get
85 + ∠GXD + 20 = 180°
105 + m∠GXD = 180°
m∠GXD = 180-105 = 75°

#7
∠BXF is opposite ∠GXD which we computed in #6 to be 75°
So m∠BXF = m∠GXD = 75°

The approximate population 3 years after the population started being recorded is 2584.

What is an exponential function:

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

Given that,

The population of a community is modeled by this exponential function, where x represents the number of years since the population started being recorded:

p(x) = 2,400(1.025)×

Plug x = 3 years in the above function.

P(3) = 2400(1.025)³

P(3) = 2400x1.0768

P(3) = 2584.53 ≈ 2584 people

How many years would population will be 1,000,000?

The year that the population of the city would reach 1,000,000 can be determined by first of all computing the number of years beginning from 1990 that it would take the population size of 400,000 to reach 1,000,000

FV=PV*(1+G)^n

FV=future population size=1,000,000

PV=present population size=400,000

g=population growth rate per year=5%

N=number of years it takes population to become 1,000,000=unknown

1,000,000=400,000*(1+5%)^N

1,000,000/400,000=(1+5%)^N

The range of the quadratic function is {y |0 ≤ y < 9}

The range of a function is the set of output values of the graph. This in other words mean the range of a function is the set of y values of the graph.

From the question, we have the following parameters:

Write out the vertex

So, we have

Vertex = (0, 0)

Remove the x value

y = 0

From the question, we have

The parabola opens upward

This means that the vertex is a minimum

So, the range is

y ≥ 0

Rewrite as

0 ≤ y

Recall that:

Closed circle point = (-2, 4)

Open circle point = (3, 9)

Remove the x values

Closed circle point = 4

Open circle point = 9

Remove the smaller y value

Open circle point = 9

This means that the highest value of y is at open circle point = 9

This is represented as

y < 9

So, we have

0 ≤ y and y < 9

Combine both

0 ≤ y < 9

Rewrite properly as

{y |0 ≤ y < 9}

Hence, the range of the quadratic function is {y |0 ≤ y < 9}

The solution is 10

Firstly rewriting the equation to frame the steps of solution -

√(5x-1) + 3 = x

Shifting 3 to the Right Hand Side of the equation -

√(5x-1) = x - 3

Now taking square of both sides of the equation

(√(5x-1))² = (x - 3)²

On solving the square we get the equation -

(5x - 1) = x² + 9 - 6x

Further solving the equation -

5x - 1 - 9 = x² - 6x

5x - 10 + 6x = x²

x² - 11x + 10 = 0

Solving the equation by factorizing -

x² - 1x - 10x + 10 = 0

x (x - 1) - 10(x - 1) = 0

(x - 1)  (x - 10) = 0

x = 1, 10

Keeping the value of x in equation to find the solution and check the results-

x = 1

√(5×1-1) +3 = 1

√(5 - 1) + 3 = 1

√4 + 3 = 1

2 + 3 = 1

5 = 1

x = 10

√(5×10-1) +3 = 10

√(50 - 1) + 3 = 10

√49 + 3 = 10

7 + 3 = 10

10 = 10

Since, 10 = 10, the result is correct.

The relationship must hold for the point to be equidistant from the origin and the x z-plane is a^2+b^2+c^2 > b^2.

What is equidistant point:

A point is said to be equidistant from two other points when it is at an equal distance away from both of them. For example, the perpendicular bisector of a line segment is equidistant from both endpoints.

Now,

distance from P(a, b, c) and the Origin (0,0,0)

[tex]\sqrt{(a-0)^2+(b-0)^2+(c-0)^2} =\sqrt{a^2+b^2+c^2}[/tex]

distance from p(a ,b, c) and the x-z plane

[tex]\sqrt{(0-0)^2+(b-0)^2+(0-0)^2} = |b|[/tex]

Here,

P is equidistant from the Origin and the x - z plane

[tex]\sqrt{a^2+b^2+c^2} = |b|[/tex]

[tex]a^{2} +b^2+c^3 = b^2[/tex]

[tex]a^{2} +c^2 = 0[/tex]

Hence a=c=0 ,thus the point P must be of the form (0,b,0) for any b ∈R

Again,

point P far the from the origin than from the x z plane

[tex]\sqrt{a^2+b^2+c^2} > |b|[/tex]

[tex]a^{2} +b^2+c^2 > b^2[/tex]

[tex]a^{2} +c^2 > 0[/tex]

Hence a, c ∈R such that atleast one of the a ,b ,c is non-zero.
