The solutions to the system of equations f(x) = x² + x - 6 and g(x) = -2x² - 2x + 12 are (-3, 0) and (2, 0). So, correct option is 1.

To graph the functions f(x) and g(x) using a calculator, we can enter the equations into the calculator's graphing function and choose an appropriate window to display the graph. Once the graphs are displayed, we can look for the points of intersection to find the solution to the system of equations.

Using a graphing calculator, we can see that the graphs of f(x) and g(x) intersect at two points: (-3, 0) and (2, 0). These points represent the x-coordinates of the solutions to the system of equations.

To verify that these points are indeed the solutions, we can substitute each of them into both equations and check that they satisfy both equations simultaneously.

For point (-3, 0):

f(-3) = (-3)² + (-3) - 6 = 0

g(-3) = -2(-3)² - 2(-3) + 12 = 0

Therefore, (-3, 0) is a solution to the system of equations.

For point (2, 0):

f(2) = 2² + 2 - 6 = 0

g(2) = -2(2)² - 2(2) + 12 = 0

Therefore, (2, 0) is also a solution to the system of equations.

The point (0, -6) and (0, 12) are not the points of intersection and (-6, 12) is not a solution to the system of equations.

Therefore, the answer is option 1.

We have,

the total amount to spent on amusement park = $214.50

And the parking fees = $12

The ticket cost per person = $33.75

let the number of person be x.

Then, the equation can become as

Answer:

x = 12

Step-by-step explanation:

If you're bored of solving equations the normal way, why not try this fun and easy method? Just follow these simple steps:

Subtract 3/10 x from both sides to eliminate the x term on the right side. This is like getting rid of the annoying person who always sits next to you in class.

4/5 x - 3/10 x + 15 = 21

Simplify the left side by finding the common denominator and combining the fractions. This is like putting all your candy in one bag and eating it faster.

(8/10 - 3/10) x + 15 = 21

5/10 x + 15 = 21

Subtract 15 from both sides to isolate the x term on the left side. This is like taking away your allowance and making you do chores.

5/10 x = 21 - 15

5/10 x = 6

Multiply both sides by 10/5 to solve for x. This is like giving you a magic wand that makes everything easier.

(10/5) (5/10) x = (10/5) (6)

x = 12

This is the solution of the equation. You can check it by plugging it back into the original equation and verifying that both sides are equal. Or you can just trust me

Given data ,

There were 15 inches of snow on the ground on Monday morning. As the temperature increased, 3 inches of snow had evaporated by Tuesday morning. By Wednesday morning, three more inches had melted, and the pattern persisted.

The following factors affect this situation:

Time: Indicates how many days have elapsed since Monday morning.

Measures how much snow is still on the ground in inches.

Given that the amount of snow is reducing by a given amount every day, the situation may be modelled using a linear function.

f(t)= 15-3t

when f ( t ) = 0

15 = 3t

Divide by 3 on both sides:

t = 5 days

Therefore, after 5 days, all of the snow will have melted.

Juliana and Brody hiked a total distance of 6 1/2 miles, which is the sum of the distances of the two trails they hiked 3 2/3 miles and 2 5/6 miles.

To find the total distance hiked by Juliana and Brody, we need to add the distances of the two trails they hiked.

3 2/3 + 2 5/6 can be written as a common fraction by finding the least common multiple (LCM) of the denominators, which is 6.

3 2/3 can be written as 11/3, and 2 5/6 can be written as 17/6.

So, 3 2/3 + 2 5/6 = 11/3 + 17/6

We need to find a common denominator, which is 6

11/3 + 17/6 = 22/6 + 17/6

Adding the two fractions, we get

22/6 + 17/6 = 39/6

The following are the correct vertical translation and you can use this information to fill the table in the picture:

A vertical translation refers to a type of transformation that moves a function or graph vertically up or down without changing its shape. Specifically, a vertical translation of distance c is given by the function:

f(x) + c

where f(x) is the original function and c is a constant that determines the amount and direction of the translation. If c is positive, the graph of the function is shifted upwards; if c is negative, the graph is shifted downwards.

For example, the function f(x) = x^2 has a graph that is a parabola opening upwards. If we apply a vertical translation of 2 units, the resulting function is:

f(x) + 2 = x^2 + 2

The graph of this function is also a parabola, but it has been shifted vertically upwards by 2 units. Similarly, a vertical translation of -3 units would give us the function f(x) - 3 = x^2 - 3, which is the same parabola shifted downwards by 3 units.

The probability that a randomly selected bicyclist who tests positive for steroids actually uses steroids is 0.763 (rounded to three decimal places).

We can use Bayes' theorem to calculate the probability that a randomly selected bicyclist who tests positive for steroids actually uses steroids. Let A be the event that a randomly selected bicyclist uses steroids, and B be the event that a randomly selected bicyclist tests positive for steroids. Then, we want to find P(A|B), the probability that a bicyclist uses steroids given that they test positive for steroids:

P(A|B) = P(B|A) * P(A) / P(B)

where P(B|A) is the probability of testing positive given that the bicyclist uses steroids, P(A) is the prior probability of a bicyclist using steroids, and P(B) is the probability of testing positive for steroids.

We are given that P(A) = 0.08, P(B|A) = 0.94, and P(B|not A) = 0.09. We can calculate P(B) using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= 0.94 * 0.08 + 0.09 * 0.92

= 0.0976

where P(not A) = 1 - P(A) = 0.92.

Substituting the values we have:

P(A|B) = 0.94 * 0.08 / 0.0976

= 0.763

Therefore, the probability that a randomly selected bicyclist who tests positive for steroids actually uses steroids is 0.763 (rounded to three decimal places).

An equation in slope-intercept form for the line shown in the graph is x = -1.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (0 - 3)/(-1 + 1)

Slope (m) = -3/0

Slope (m) = 0.

At data point (-1, 3) and a slope of 0, a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

Answer:

-8.5 and 7.5

Step-by-step explanation:

Let's call the two numbers x and y. We know that their difference is 16, so we can write:

x - y = 16 or x = y + 16

We want to find the values of x and y that minimize the expression:

x + y + xy

Substituting x = y + 16, we get:

(y + 16) + y + (y + 16)y

Simplifying and expanding, we get:

y^2 + 17y + 16

To minimize this expression, we can take its derivative with respect to y and set it equal to 0:

d/dy (y^2 + 17y + 16) = 2y + 17 = 0

Solving for y, we get:

y = -8.5

Substituting y = -8.5 into x = y + 16, we get:

x = 7.5

Therefore, the two numbers with a difference of 16 such that the result of adding their sum and their product is a minimum are -8.5 and 7.5.

Answer:

Let's start by using algebra to represent the given information.

Let the son's current age be "s" and the mother's current age be "m". We know from the problem that:

m = 3s (the mother is 3 times as old as her son is now)

and

m - 14 = 10(s - 14) (fourteen years ago, the mother was 10 times as old as her son was then)

Now we can solve for the son's age:

m - 14 = 10s - 140 (distribute the 10)

m = 10s - 126 (add 14 to both sides)

3s = 10s - 126 (substitute m = 3s)

7s = 126

s = 18

Therefore, the son is currently 18 years old. To check this answer, we can use the first equation to find the mother's current age:

m = 3s = 3(18) = 54

So the mother is currently 54 years old, and 14 years ago the son was 4 years old and the mother was 40 years old, which is 10 times as old as the son.

In the above isosceles trapezoid,

Since R is the midpoint of HN, HR = RN. Similarly, since T is the midpoint of KJ, KT = TJ.

Let's use these properties to write expressions for HJ and NK in terms of x:

HJ = 5x + 9

NK = 3x - 2

Since NKJH is an isosceles trapezoid, we know that HJ = NK + 2RT. Substituting the expressions we found earlier, we get:

5x + 9 = (3x - 2) + 2(3x + 6)

Simplifying this equation gives:

5x + 9 = 9x + 10

Subtracting 5x from both sides gives:

4 = 4x

Dividing both sides by 4 gives:

x = 1

Now that we know x, we can find the values of HJ, NK, and RT:
