Write the equation of the line that passes through the points (8, -4) and (-2,5).

Sladkaya [172]

Answer:

The equation in the slope-intercept form will be:

Step-by-step explanation:

Given the points

(8, -4) and (-2, 5)

The slope between two points

$m=\frac{5-\left(-4\right)}{-2-8}$

$m=-\frac{9}{10}$

As the point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -9/10 and (8, -4)

$y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)$

Writing the line equation in the slope-intercept form

$y=mx+b$

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

so the equation in the slope-intercept form will be:

$y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)$

$y+4=-\frac{9}{10}\left(x-8\right)$

subtract 4 from both sides

$y+4-4=-\frac{9}{10}\left(x-8\right)-4$

$y=-\frac{9}{10}x+\frac{16}{5}$

Therefore, the equation in the slope-intercept form will be:

$y=-\frac{9}{10}x+\frac{16}{5}$

Solve the equation for x, where x is a real number (5 points): <br> -3x^2 + 6x + 9 = 7

lana66690 [7]

Add -7 to both sides so that the equation becomes -3x^2 + 6x + 2 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                                       x = [ -b ± √(b^2 - 4ac) ] / (2a)
                                       x = [ -6 ± √((6)^2 - 4(-3)(2)) ] / ( 2(-3) )
                                       x = [-6 ± √(36 - (-24) ) ] / ( -6 )
                                       x = [-6 ± √(60) ] / ( -6)
                                       x = [-6 ± 2*sqrt(15) ] / ( -6 )
                                       x = 1 ± -sqrt(15)/3
The answers are 1 + sqrt(15)/3 and 1 - sqrt(15)/3.

sdas [7]

The probability of the player missing a shot at least once is 1.00 - 0.70 = 0.3.
Therefore the average number of missed double goals in 2500 trials is given by:
$2500\times0.3=750$
