The table of ordered pair is an illustration of a linear function.

The value of y when x = 8 is -8

From the table (see attachment), we have the following highlights

When x = 10, y = -12

So, when x decreases by 2 (to 8), the value of y will increase by 4 (to -8).

Hence, the value of y when x = 8 is -8

Answer:

y = 2x + 54

Step-by-step explanation:

slope of equation:

(y2-y1)/(x2-x1)

= (72-58)/(9-2)

= 14/7

= 2

y = 2x + b

58 = 2(2) + b

58 = 4 + b

b = 54

k=7

given a quadratic polynomial

ax^2+bx+c

the sum of the roots is given by -(b/a)

and the product of the roots as (c/a)

hence we get sum of roots as -(-(k+6)/1) and product of roots as (2(2k-1))/1

since the sum is equal to half the Product then we get

k+6=2k-1 and solving for k we get 7

Answer:

a) 18

Step-by-step explanation:

There are three possible outcomes for every amount of GB and since there are 6 different quantities of GB then we get:

6×3=18 possible outcomes.

Step-by-step explanation:

Adding 10 to both sides of the original equation gets us q = 6(r + 1) + 10. Since q is equal to h(r), we get h(r) = 6(r + 1) + 10 = 6r + 16.

Step-by-step explanation:

[tex] (x + 15)^2 - 10 = 0\\

(x + 15)^2 = 10 \\

(x + 15) = \pm\sqrt {10} \\

x + 15 = \pm 3.16227766\\

x + 15 = \pm 3.16\\

x = \pm 3.16 - 15\\

x = 3.16 - 15 \: or \: x = - 3.16 - 15\\

Answer:

1) On the x-axis, the arm span is plotted. On the y-axis, the height is plotted. It is chosen to be that way because the numbers on that have been assigned on the x-axis increase and decrease in a small amount, while the numbers on the y-axis increase and decrease in a huge amount.

2) (lolz i cant show u my work but i will try my best with explanations even tho ian allat.) So, Using the slope formula, I got a the equation y=x+15. The equation was determined with the formula m=y2-y1/x2-x1. The points that were used included (37,40) and (47,50). After finding the slope, I did the best guess for the y-intercept, which is known as b in y=mx+b.

3) The slope of the line represents the time it takes for the arm span and the height. The y-intercept represents the height that the arm span starts developing or gets bigger.

4) It fits perfectly

Answer:

9 degrees Celsius

Step-by-step explanation:

I graphed the function on the graph below to find the maximum of the parabola. The maximum is at (9,200), which means at 9 degrees Celsius, there are 200,000 fish.

The temperature at which there will be maximum number of fishes is given by the point (9, 200), is it is 9 degrees.

Given data:

To find the temperature that will result in the maximum number of fish, determine the x-value (temperature) at the vertex of the quadratic function.

The given function is P(x) = -2(x - 9)² + 200, where P(x) represents the fish population in thousands and x represents the water's temperature.

The general form of a quadratic function is y = a(x - h)² + k, where (h, k) represents the vertex of the parabola.

The vertex form of the function is P(x) = -2(x - 9)² + 200.

Comparing this to the general form, the vertex of the parabola is at the point (9, 200).

Hence, the temperature that will result in the maximum number of fish is 9 degrees (the x-value of the vertex).

Step-by-step explanation:

Answer:

Step-by-step explanation:

A graph representing direct variation must pass through the origin.

The graph through (- 4, 3) and (4, 3) is a horizontal line and does not go through the origin.

Thus the line does not represent a direct variation because it does not go through the origin.

Answer: Company B

Step-by-step explanation:

First we must calculate the area of the carpet. Variable A represents area.

[tex]14*12=A[/tex]

[tex]A=168[/tex]

So the area of the carpet is 168 square feet.

To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

[tex]168*2.75= Company A\\[/tex]

Company A charges, $462, while Company B will charge $450 for the one room.

This means Company B has the better price.

Answer:

[tex]\displaystyle p > \frac{1}{4}[/tex].

Step-by-step explanation:

Expand the left-hand side of this equation:

[tex]p\, (x + 1)\, (x - 3) = p\, \left(x^2 - 2\, x - 3\right) = p\, x^2 - 2\, p\, x - 3\, p[/tex].

Collect the terms, so that this quadratic equation is in the form [tex]a\, x^2 + b\, x+ c = 0[/tex]:

[tex]p\, x^2 - 2\, p\, x - 3\, p = x - 4\, p - 2[/tex].

[tex]p\, x^2 - (2\, p + 1)\, x + (p + 2) = 0[/tex].

In this equation:

Calculate the quadratic discriminant of this quadratic equation:

[tex]\begin{aligned}b^2 - 4\, a\, c &= (-(2\, p + 1))^2 - 4\, p\, (p + 2) \\ &= 4\, p^2 + 4\, p + 1 - 4\, p^2- 8\, p = -4\, p + 1\end{aligned}[/tex].

A quadratic equation has no real root if its quadratic discriminant is less then zero. As a result, this quadratic equation will have no real root when [tex]-4\, p + 1 < 0[/tex]. Solve for the range of [tex]p[/tex]:

[tex]\displaystyle p > \frac{1}{4}[/tex].

Answer:

-40\sqrt{3}

-.69.282

Step-by-step explanation:

Answer:

3. 12.5π + 100

6. 25π + 250

Step-by-step explanation:

3. So you can first calculate the area of the square, which is 100.

Then you have to calculate the semicircle.

You can see that the diameter is 10.

The radius is 5.

The area of the semicircle is 12.5π

Total area is 12.5π + 100

6. You have a one rectangle and two semicircles.

You can calculate the area of the semicircles first.

25π

Then, you have to see how much the width of the rectangle is.

You can see that the total width is 35, and the radius of each semicircle is 5.

35 - 5 - 5 = 25

The width is 25 so the area of the rectangle is 250.

The total is 25π + 250.
