Answer:

Step-by-step explanation:

(hypotenuse)² = (adjacent)² + (opposite)²

(opposite)² = (hypotenuse)² - (adjacent)²

(adjacent)² = (hypotenuse)² - (opposite)²

up row

1) x² = 9² + 7² = 81 + 49 = 130

x = 11.4 cm

2) x² = 6² + 4² = 36 + 16 = 52

x = 7.2

3) x² = 4.3² + 7.7² = 18.49 + 59.29 = 77.78

x = 8.8 cm

Down row

1) x² = 7² - 3² = 49 -9 = 40

x = 6.3 cm

2) x² = 6.4² - 2.9² = 40.96 + 8.41 = 49.37

x= 7.02 cm

3) x² = 7.2² - 5.3² = 51.84 - 28.09 = 23.75

x = 4.9 cm

Let n be the number of couples dancing in a competition. If there are 5 organizers, which expression represents the total number

Korvikt [17]

2n+5...a couple is two people so you need to multiply the number of couples, n, by 2 to get the total number of dancers. Then add the total number of organizers.

Answer:

The line equation in slope-intercept form is:

$y\:=-\frac{2}{5}x+4$

Hence, option D is true.

Step-by-step explanation:

Given the points

(0, 4)

(5, 2)

Finding the slope between the points

$\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(5,\:2\right)$

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

$m=\frac{2-4}{5-0}$

$m=-\frac{2}{5}$

As the y-intercept is obtained by setting the value x = 0.

As we know that when x = 0, the vale of y-intercept y = 4

so the y-intercept is b = 4.

As the slope-intercept form is

substituting the slope m = -2/5 and the y-intercept b=4

$y = mx+b$

$y\:=-\frac{2}{5}x+4$

Therefore, the line equation in slope-intercept form is:

$y\:=-\frac{2}{5}x+4$

Hence, option D is true.
