The simplified polynomial after standard form will be;

⇒ - 8x² - 43x - 36

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The algebraic expression is;

''The expression (3x + 6)² is subtracted from x² - 7x.''

Now,

We can formulate as;

⇒ (x² - 7x) - (3x + 6)²

⇒ x² - 7x - (9x² + 36x + 36)

⇒ x² - 7x - 9x² - 36x - 36

⇒ - 8x² - 43x - 36

Thus, The simplified polynomial after standard form will be;

⇒ - 8x² - 43x - 36

The table below represents a function. Which of the following equations could be its function rule?

worty [1.4K]

Answer:

$y=2x-2$ is the required equation.

Therefore, the second option is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation of a linear function is given by

$y=mx+b$

where m is the slope and b is the y-intercept

Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)$

$m=\frac{0-\left(-2\right)}{1-0}$

$m=2$

substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.

$y=mx+b$

$-2 = 2(0)+b$

$-2=0+b$

$b=-2$

Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function

$y=mx+b$

$y=2x+(-2)$

$y=2x-2$

Thus, $y=2x-2$ is the required equation.

Therefore, the second option is true.

4)
pine tree is most numerous on tree farm which is 40%

5)
if 480 trees total,
pine trees = 480 x 0.40 = 192 trees

6)
if 480 trees total,
spruce trees = 480 x 0.30 = 144 trees
(p.s. also firm trees = 144 (same as spruce trees)

The diameter of the earth is about 7900 miles. The diameter of Jupiter is about 88,800 miles, approximately 11 times that of the

jeka94

<span>We know that the surface of a sphere is: S = 4 * pi * r^2 The surface of Earth is : Se = 4 * 3.1416 * (7900/2)^2 = 196,066,797.51 And the Jupiter is : Sj = 4 * 3.1416 * (88800/2)^2 = 24,772,840,374.32 So the surface of Jupiter is around 11^2 times bigger than the Earth</span>
