Answer:

y = 28.1739x² + 45.6478x + 617.4879 ;

$3891.36

Step-by-step explanation:

Given the data above :

We can employ an online quadratic model calculator to create a quadratic model of the data:

Year(t) ____0 ____1 ____2 ____3 ____4 ____5 (P)-603.46_695.39_871.96_972.35_1224.53_1571.52

The quadratic function obtained is :

y = 28.1739x² + 45.6478x + 617.4879

Using the model ; the price of gold in 2016 will be :

X = 2016 = 10 years (2016 - 2006)

y = 28.1739(10)^2 + 45.6478(10) + 617.4879 = 3891.3559

Hence, the predicted price of gold in 2016 using the model will be $3891.36

Answer:

y= -3/4x+3

Step-by-step explanation:

The general equation is y=mx+b with m representing the slope, and b representing the y-intercept. So if you are given the slope and y-intercept, you just plug those in for m and b respectively. Hope this helps!

Answer:

Step-by-step explanation:

put x=8

y=1/8×8+3=1+3=4

so point is (8,4)

put x=0

y=1/8×0+3=0+3=3

so point is (0,3)

to find more points put x=multiple of x and then find y.

C to find black jelly beans = g + 4

Answer:

n=-0.425

Step-by-step explanation:

subtract 16.2 from both sides. divide 8 from both sides

Answer:

N= -1.825

Step-by-step explanation:

First, we must isolate the variable. So we can write 8N+16.2=1.6. Let's subtract 16.2 from both sides of the equal sign. So now we have 8N=-14.6. Now we have to only get N, so we must divide every side by 8. We do this to cancel out the 8 multiplying the N. We get N= -1.825. This is your answer!

I hope this helped you solve this problem and help you solve future problems!

Kennet 25,Andrew 15,Billy 30,Cameron 7

Step-by-step explanation:

Kenneth - 10+x,

Andrew - x,

Billy - 2x,

Cameron - x - 8,

10 + x + x + 2x + x - 8 =77

5x = 75

x = 15 (Andrew)

10+15= 25 (Kenneth)

2×15=30 (Billy)

Answer:

m = 4/5 (slope)

_____________________________

y = 4/5x - 1 (slope intercept)(y = mx + b)

- 4x + 5y = - 5 (standard form)(Ax + By = C)

y + 5 = 4/5(x + 5) (point slope)(y - y1 = m(x - x1))

Step-by-step explanation:

All you need to do is remember the equation for slope: m = y2-y1/x2-x1

Where your first point is (x1,y1), and your second point is (x2,y2), and m is slope(rate of change : change in y over change in x).

Your first point starts with the smallest x: (-5,-5), then your second point is the greater x: (5,3)

Then just substitute, and solve:

y2-y1/x2-x1 →

3-(-5)/5-(-5) = 3+5/5+5 = 8/10 = 4/5

Extra information:

point slope:

y-y1 = m(x-x1).

Where (x1,y1) is the first point, (x,y) is the second point, and m is the slope. (note: the second point does not have 2 as a subscript so it can be set to slope intercept(y = mx + b) as an equation. This is because you could be given one point, and a slope, and be told to find the other)

Then just plug the coordinates into the equation, and solve for the equation of this line.

Since we already know what the slope is, we can just solve for the general equation given one point:

y-y1 = m(x-x1)

y+5 = 4/5(x+5). (point slope)

y + 5 = 4/5x + 4

-5 -5

____________

y = 4/5x - 1

(slope intercept)

Given slope, another way to find the y intercept is to multiply the current x coordinate by the slope, and add it to the current y value.

given a point (5,3), and a slope of 4/5. The line will be y = slope × x + (y2 - (m × x2)),

y = 4/5 × x + (3 - (4/5 × 5))

y = 4/5x + (3 - 4)

y = 4/5x - 1

Answer:

The answer is Y=8.5+0.18x

Step-by-step explanation:

Given data

Let the flat fee be $8.5

Let the additional fee per ounce be $0.18

Let the total amount to mail the package be y

Therefore the total amount is

Y=8.5+0.18x

The function is Y=8.5+0.18x

Answer:

Ur question doesnt make sense

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

This is the general rule for any function, where a function cannot have more than one x value for every y value, there is only one output for every input.

You can also use the vertical line test which states that anything that hits the line more than once is not a function.

Answer:

x= negitive 6/8

Step-by-step explanation:

Ok think about it 1/4 plus 1/2 is 3/4

so how do i go to negitives?

you double the amount of it and then minus it

because 3/4- 3/4 would be zero

so you have to double it to get that answer

Answer:

The equation is  [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

The Equation is formed from two sides equal to each other

∵ One eighth means [tex]\frac{1}{8}[/tex]

∴ Negative one eighth means  [tex]-\frac{1}{8}[/tex]

→ Assume that the number is x

∵ "of" means times

∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] × (x)

∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] x

∵ Negative one eighth of a number is [tex]-\frac{3}{4}[/tex]

→ "is" means equal, so the left side is [tex]-\frac{1}{8}[/tex] x and the right side is [tex]-\frac{3}{4}[/tex]

∴  [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex] ⇒ Equation

∴ The equation is  [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]

Answer:

100x+75=y

Step-by-step explanation:

Answer:

y=100x+75. Where y equals total cost and x equals numbers of weeks enrolled.

Step-by-step explanation:

75 is the upfront cost, aka the cost of zero weeks, this cost will never change and is a one-time payment, therefore it needs no variable. 100 is the cost per week which means every week costs 100 more dollars, this is why it must have a variable because it will change with time. They are added together because they both show the total cost and together will show how much one person is spending.

C is actually the correct answer. Cos formula is adjacent/hypotenuse!

Step-by-step explanation:

The cosine ratio for the given figure is cos θ = 12/13. Therefore, option C is the correct answer.

We need to find which is the correct cosine ratio for the given figure.

The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle.
That is cos θ=Adjacent/Hypotenuse.

From the given figure, cos θ = 12/13

The cosine ratio for the given figure is cos θ = 12/13. Therefore, option C is the correct answer.

Answer:

2x + 4y = 110

Step-by-step explanation:

Let

The quantity of small tables = x

The quantity of large tables = y

The smaller tables can fit 2 people, the larger tables can seat 4 people.

Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.

Number of people×quantity (small table) + number of people×quantity (large table) = 110

2x + 4y = 110
