Correct answer: y>-32x-2

The required equation of inequality is y >  - 3/2 x + 2.

We have given a graph of inequality for finding their equation.

What is inequality?

Inequality is a statement of an order relationship for greater than, greater than or equal to, less than, or less than or equal to, between two numbers or algebraic expressions.

From graph we can see that the line is passing through the points (0,-2) and (-4,4).

Since we know that the slope of a graph,

[tex]m = (y_2 - y_1)/(x_2 - x_1 )[/tex]

    =[tex](4 - (-2))/(-4 - 0)[/tex]

⇒[tex]m = (-3)/( 2)[/tex]

Also we know the equation of line passing through the point (x_(1,)  y_1) having slope be,

[tex]y - y_1 = m (x - x_1)[/tex]

Therefore, the equation of line passing through (0, -2) and having slope -3/2 be,

⇒ y - (-2) = - 3/2 x

⇒ y =  - 3/2 x + 2

Since the graph is shaded left side to the line so, this equation can be written as

y >  - 3/2 x + 2

Thus, this is the required equation of inequality.

Answer:

4a. 13

4b. -4

Step-by-step explanation:

2x-6/5 = 4 (Muti each side by 5)

2x-6 = 20

2x = 26 (Divide each side by 2)

x = 13

7- 2x/4 = 9

-2x/4 = 2 (Muti each side by 4)

-2x = 8 (Divide each side by -2)

x = -4

Answer:

Read the step-by-step for the entire answer!!!

Step-by-step explanation:

Whenever you have situations like these you have to look at it from the perspective given.

If you are throwing a ball it's going to start at ground 0 where the child is, therefore the height of the child is how high off the ground the ball is at 0 seconds.

If it is thrown, and it is stuck in the tree for a few seconds, then that means on the graph you will see an incline of the graph, and then a stale line for a few seconds as the ball is stuck in the same height for a few seconds.

After the ball falls down, then so will the height of the ball.

t - a function of time, is always on the x-axis because time variables are usually on the x-axis of a graph.

I choose seconds as a measurement of time because in a realistic situation a ball will be in the air for seconds.

h - the height of the ball, will be on the y-axis of the graph because it is a dependent variable (i.e. the height of the ball is dependent on how long the ball is in the air for).

Answer:

2. 0-6

3. 0-6

Step-by-step explanation:

This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

(ik you might not need this anymore, but I'm hoping it proves useful to others)

All three numbers in the set are in the range it would mean that all three couples prefer indoor weddings is  0-9, 0-6 and 0-6.

We have given that,

An event organizer found that 70% of young couples prefer to have indoor weddings instead of outdoor weddings.

The Range is the difference between the lowest and highest values.

This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

Answer:

The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Step-by-step explanation:

Total members=13000

Membership charge per month=$7

Increase in Membership charge per month=$1

For each $1 monthly increase in membership fee, the club loses approximately=500 members

For 1 month, 1 dollar decrease is 500 × 1

For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]

The increase in membership fee is 7 + [tex]x[/tex]

After that,

Monthly revenue = Number of members × Monthly fee

Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]

[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Answer: B -4

Step-by-step explanation:

Value of coefficient of the squared term in the parabola's equation = -4

Correct option is B.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

Given,

Vertex of parabola (h,k) = (3, 5)

y = 6 for x = -1

Parabola opens horizontally left side

Vertex-form equation of parabola

x = a(y - k)² + h

-1 = a(6 - 5)² + 3

-1 = a(1) 3

a = -4

Hence, -4 is value of coefficient of the squared term in the parabola's equation.

Decay

B)

Initial value is 5.

C)

The decay factor is 0.75.

D)

75%

Step-by-step explanation:

An exponential function is given by:

[tex]f(x)=a(r)^x[/tex]

Where a is the initial value and r is the rate.

We have the function:

[tex]y=5(1/4)^x[/tex]

So, a = 5 and r = 1/4.

A)

Remember the guidelines:

Our rate is 1/4 or 0.25.

It is less than 1, so our function is exponential decay.

B)

The initial value is the value in front of our rate.

So, our initial value in this case is 5.

C)

The decay factor will be 1 - r, where r is our rate.

Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.

So, we are decaying by a factor of 0.75.

D)

To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.

So, 0.75 will be 75.0 % or smply 75%.

It is a 75% decay.

Answer:

9.9 feet per second

Step-by-step explanation:

y=9.5+0.4

y=9.9

Marcella's average speed in feet per seconds is,

⇒ y = 9.54 feet

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,

⇒ y = 9.50x + 0.4

Hence, Marcella's average speed in feet per seconds is,

y = 9.50x + 0.4

Put x = 1;

y = 9.50 × 1 + 0.4

y = 9.50 + 0.4

y = 9.54 feet

Thus, Marcella's average speed in feet per seconds is,

⇒ y = 9.54 feet
