b.15
c.20
d.40​

Answer:

800 spectators

Step-by-step explanation:

Using the survey provided above, we can see that the survey population is a total of 150 spectators by adding up all of the spectators. Since only 50 spectators attended 5 or more games then that means that the percentage of the survey population that attended 5 or more games is ...

50 / 150 = 0.3333 or 33.33%

Therefore, if we are supposing that 2,400 spectators attended at least one game this season then we can multiply this population by the percentage of people who tend to attend 5 or more games in order to actually calculate the total number of people who will attend 5 or more games this season.

2,400 * 0.3333 = 800 spectators

Answer:

y = -x - 4

Step-by-step explanation:

Plug in the point and slope into the equation y = mx + b, and solve for b:

y = mx + b

-6 = -1(2) + b

-6 = -2 + b

-4 = b

Then, plug in b and the slope into y = mx + b

y = -1x - 4

y = -x - 4 is the equation of the line

Answer:

-27

Step-by-step explanation:

A parabola is a curve with a focus and a directrix. The focus is any point is at an equal distance while the directrix  is a fixed line. The vertex of the parabola is (2,1), the two points to the right are (3,4) & (4,13) while the two points to the left are (1,4) & (0,13).

Given that:

[tex]y = 3(x - 2)^2 + 1[/tex]

A parabola is represented as:

[tex]y = a(x - h)^2 + k[/tex]

Where:

[tex]Vertex = (h,k)[/tex]

So, by comparison; the vertex of the function is:

[tex]Vertex = (2,1)[/tex]

To plot two points to the right, we select x values greater than 2.

Let: [tex]x = 3[/tex]

So, we have:

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(3 - 2)^2 + 1[/tex]

[tex]y = 4[/tex]

Let [tex]x = 4[/tex]

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(4 - 2)^2 + 1[/tex]

[tex]y =13[/tex]

To plot two points to the left, we select x values less than 2.

Let: [tex]x=1[/tex]

So, we have:

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(1 - 2)^2 + 1[/tex]

[tex]y = 4[/tex]

Let [tex]x = 0[/tex]

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(0 - 2)^2 + 1[/tex]

[tex]y =13[/tex]

Answer:

x = 5 which mean that if you replace 5 with the x you will get 90 as your answer.

Step-by-step explanation:

Answer:

x=5

Step-by-step explanation:

∠17x+5≅∠18x

17x-18x=-5

-x=-5

x=5

17x5+5=90°

18x=90°

Answer:

C) (0,5)

Step-by-step explanation:

f(x) is y and x is x

The table is providing you with points

y-y over x-x gives you a slope of -5

Use the points and turn it into a point-slope equation and convert to y-intercept equation

y-15=-5(x+2)

y-15=-5x-10

y=-5x+5

So the y-intercept is 5 or (0,5)

Answer:

y=9x+60

Step-by-step explanation:

An equation in slope-intercept form to find the height (in feet) of the tree, y, after x years is y=9x+60.

Given that, the tree grows at an approximate rate of 9 inches per year.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

We know that, 1 feet =12 inches

So, 5 feet =60 inches

Let the height of the tree be y and the number of years be x.

Now, equations is y=9x+60

Therefore, an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years is y=9x+60.

Step-by-step explanation:

To graph that you would start at 4 because that's your y-intercept then you would move down by 1 because z is considered 1 and the negative is only applied to the rise and the run is 3 so from point 3 you would move to the right 3 times and that would be your second point.

Answer:the answer would be A

Step-by-step explanation:

30 divided by 8 = 3.75 which is the ammount of money per galon that Todd spent. There is a 7 cent difference between the ammount todd payed per gallon and the ammount Hope payed for gallon.

Todd paid $0.07 more per gallon of gasoline than Hope is the correct alternative.

Given is that Todd purchased 8 gallons of gasoline for $30. The equation y = 3.68x represents the cost in dollars, y, Hope paid for purchasing x gallons of gasoline.

Unit rate of gasoline in case of Todd will be -

{T} = (30/8) = $3.75

Unit rate of gasoline in case of Hope -

{T} = (30/8) = $3.68

We can write -

$3.75 - $3.68

$0.07

Therefore, Todd paid $0.07 more per gallon of gasoline than Hope is the correct alternative.
